How can a wall be painted
Are you prepared to paint a wall? Do not skip the job of preparation: a correctly arranged surface makes all the difference. This video demonstrates how a snap can be made for both painting and priming.

What do you need?'
Cellulose sponge, dishwasher, painter's tape, base, paint, paint tray, paint roller, two-inch paint brush, ladder



Take these steps

1.Purify the walls
Using a big sponge of cellulose and a water solution combined with a few drops of gentle dishwashing liquid, clean your walls to remove any dust, dirt, and fat.

2.Adjust the trim
Use the blue painter paper (not masking tape) to protect any fields that your paint doesn't want to get on, such as trimming, molding, door knobs, window screens, and door panels: run lengthy tape rows just inside the exterior corners of those areas.

3.Pour the first in a cabinet
Pour in enough to nearly fill the well down the table without filling the pointed part of the table where the pads are.


4.Roll the first on the screen
Dip your stick into the primer, roll it back and forth a couple of occasions across the sheets of the tray to remove any surplus and avoid dripping. Make sure that the wheel is covered uniformly. Run a segment of the ceiling up and down the sheet, adding the primer until the part is completely coated. Continue until your wall is completely covered, reapplying the primer as needed to the roller.   

Tip: Follow the cleaning directions of the manufacturer, which you will discover on the can, to ensure that the base is totally intact before implementing the paint.

5.The texture is painted
Dip a two-inch bent pen into the paint, only about a fifth of the manner down the pen to cover the bristles. Run the comb along the tape's exterior rim spanning the seam (on the tape's ceiling hand; not the bottom part). Continue to apply paint gently against your attached strip, work it out from the ribbon for about two or three inches. Continue to paint a tight swathe along all the labeled fields until you've completed.

6.Roll on paint in the form of a "w"
Fill a paint cabinet with paint; insert your handle and remove surplus. Roll the color 3-by-3-foot "w" form onto the ceiling. Working your route home across that "w," plug in vacant spots without raising the plate until that ceiling portion is fully coated. Continue to add more paint as required to the bin until the entire ceiling has been covered.

7.Remove the file from the painter
Peel off the paper while the paint is still moist to prevent any dissolved paint along with it from being inadvertently removed.

7 Simple steps for outer walls waterproofing

August 01, 2019 0
7 Simple steps for outer walls waterproofing
When outside walls are exposed to rainwater or high humidity, water and humidity may travel through the masonry and affect your inner walls. This implies that before drying, your walls can remain moist for a long time, which can lead to development of molds and irreparable harm. Wall harm caused by water penetration in humid regions such as Florida is not an IF issue, but a WHEN issue.






  1. Check walls for faults: outside walls waterproofing
Only if the walls become wet due to rainwater or moisture is the best option. It is essential to eliminate any other causes of structural dampness before shopping around for waterproofing goods. From cracks in your bricks or condensation inside the wall to a burst water pipe, it could be anything. You can apply a waterproofer as a preventive measure once you fix the problem.


  1. Clean your canisters
The problem with clogged gutters is not only that they can flow over the edge, down your walls; they also retain rainwater that is gradually absorbed by the wood or fascia boards of the roof, potentially leading to a number of problems, including rotting wood, leaks, and molding. By merely cleaning your gutters twice a year, you can prevent all these and maintain your house healthy.


  1. Select the correct waterproofer
Today, a number of waterproofing products are available to help homeowners protect their homes from outside moisture. Here are some of the products that you should consider:

Concrete waterproofing coating, a cement-like product that adheres continuously to concrete and masonry; it can be added to any surface, including painted walls; silicate-based concrete sealer that reacts with the components in masonry and concrete to create a waterproofing layer; this sealer can only be used on unsealed / unpainted walls; waterproofing paint comparable to acrylic coating; Choosing a breathable formulation that is specifically intended to enable walls to breathe and remove moisture is very crucial. The item can be used on earlier painted surfaces.

  1. Use waterproofing additive in plaster
Plastering can help improve esthetics, strengthen walls, and protect them from moisture entry. Although most exterior plasters have waterproofing characteristics, you can eliminate problems with water infiltration and prevent recurrence by simply adding a waterproofing admixture to the plaster

  1. Make your walls waterproof
You must first bring your walls in good condition regardless of the product chosen for waterproofing the exterior walls. This implies you need to repair cracks and patch holes with a good quality filler. Before grinding allow the filler to dry optimally. Then sand away harsh, irregular regions, remove dust by washing the surface with water, and allow the walls to dry fully to guarantee a healthy adhesion between the waterproofer and the substrate.

  1. Use the waterproofer
For applying the waterproofer, you can use roller or brush. If you require second coat, allow the first coat to dry completely and then apply the second coat. To create an impenetrable barrier against infiltration, use sufficient product.

  1. Test
To assess the efficacy of the products used for waterproofing exterior walls, conducting a watertightness test is very essential. Water should be placed on the surface of the wall for a few hours for this experiment, maintaining the nozzle at an angle of 30 degrees. Your home will only pass the test if there is no moisture in a moisture meter. You will not only discourage severe harm by waterproofing the exterior walls, but also increase the importance of your home.

Types of False Ceilings and its Applications




Types of False Ceilings and its Applications









False ceiling on suspended supports is given below the roof slab. Usually, fake celling is given for temperature control (thermal insulation for AC), light installation, or concealing electrical and other network cables, and hideous or too high ceiling.

False ceiling is an instance of contemporary, residential and commercial building and architecture.

False ceiling components or parts:
The following figure shows the various components of a false ceiling:

Types of False Ceiling:

False ceilings can be distinguished into many kinds depending on their uses, materials used, appearance and visibility.


The major classification based on materials used are listed briefly below,
  1. Gypsum Ceiling
  2. Plaster of Paris Ceiling
  3. Fiber Ceiling
  4. Wooden Ceiling
  5. Glass Ceiling
  6. Metal Ceiling
  7. Synthetic Leather or Cloth Ceiling

Gypsum False Ceiling:


Gypsum false ceiling is a calcium hydrated sulphate. This sort of false ceiling is lightweight, isolated from noise, resistant to fire, smooth and thermally insulated.

Gypsum fake ceiling comes in the form of iron frame hanging square boards. The finishing job such as paints, laminates, wallpapers and texture finishes on these boards provides a nice look.







Plaster of Paris Ceiling:

Paris Plaster (POP) is the most widely used material in false ceiling building. When gypsum is heated to some degree, POP is acquired. It provides both esthetic and functional assistance.

False ceiling plaster from Paris is appealing, almost maintenance-free and has a lengthy life span. They are very good heat and cold insulators.

Not only do these kinds of false ceiling conceal the hideous parts of structure, ventilation ducts and conduits, but they also offer the roof a smooth finish.


Fiber False Ceiling:

Due to low price and eastern installation, fiber false ceiling is in high demand for the building of false ceiling. The material used in the production of fiber ceiling panels is manufactured from natural and synthetic minerals. They come in many shapes and sizes as they are man-made.





Wooden False Ceiling:



Due to its natural textures and pattern, wooden fake ceiling is used. These kinds of false ceiling are widely used nowadays as it provides the eyes a pleasant look.

Wooden false ceiling is expensive, not used in shopping malls and hospitals, but can be installed in residential buildings. In order to get the correct look, they can be provided different finishes or painted.
Wooden false ceiling has lot of drawbacks, mostly:
  • Prone to thermite attack.
  • Prone to warping.
  • The room should be thermally controlled.


Glass False Ceiling:


Glass is one of the kinds of false ceiling used in building. It is a non-cristalline material with a fragile and transparent property. But with some admixtures, this can be changed to render it non-brittleand non-transparent.

It can be used for false ceiling since glass is a useful heat insulator. This sort of false ceiling enhances the building's esthetic appearance.


Metal Ceiling:


Since metal is a material that is difficult and durable, it is widely used in the false ceiling. It provides a shiny surface when the metal surface is polished, which is a treat for the eyes.

The metals used here are iron and aluminum galvanized. This ceiling's price is small because it's simple to install and access. It is easy to access the concealed parts of the framework as the panels are readily removable and reassembled. Building costs get lower as installation, fixation, and maintenance are small.


Synthetic Leather or Cloth Ceiling:


Either leather or cloth are the materials used in this sort of ceiling. Since both the materials used are man-made, they can be provided any shape, shape and design that enhances the esthetic perspective of the building's interior.

It is only used in temporary tents or other temporary structures as these collect dust and have low light transferring assets.

Advantages of False Ceiling:


  • It provides a smooth homogeneous surface to the roof.
  • It provides fire protection as it creates compartmentation.
  • False ceiling helps in acoustical treatment.
  • It conceals all the non-pleasing elements and hides it from the viewer’s eyes.
  • It also hides the pipelines and the electrical cables running in the room. All the ducts of air-conditioning can be hidden under it.
  • False ceiling materials are easy to install and cheap as compared to traditional roof systems.

Disadvantages of False Ceiling:


  • The most worrying aspect of having a false ceiling would be pests. They can get through into the space between and can start their own breeding which might lead to a lot of trouble.
  • Also be careful while putting up decorations or hangings while you have a false ceiling in place. Make sure you know the strength and durability, do’s and don’ts with regard to your ceiling.
  • Lastly, the false ceiling would reduce the height of the ceiling considerably and hence do not install false ceiling unless you have a decent ceiling height.

Why Use Concrete Pump?

Why Use Concrete Pump?

Why Use Concrete Pump?




How do you determine the correct concrete pumping for your project? What makes this concrete positioning technique more effective than dumping from a prepared mixing truck, bucketing with a crane or just using a wheelbarrow?

Concrete pumping helps both now and in the future to reap rewards. Contractors report high customer satisfaction levels and increased opportunities for more projects. Distinct benefits that can have a positive effect on the bottom line of a project include time and labor savings, increased revenues, improved scheduling, decreased site preparation, employee satisfaction, increased quality control, and versatility of concrete placement.

The equipment which is pumping concrete

For pumping concrete, a range of machinery may be used, including truck-mounted concrete pumps, placement booms, high-pressure / high-output trailer pumps, trailer-mounted concrete pumps, and mortar machines. Consider the following when equipping a work site with any concrete placement machinery:

  • Job location
  • Job size
  • Job complexity
  • Safety
  • Maximum distance
  • Maximum height
  • Volume of concrete to place
  • Concrete mix design, slump, aggregate, and admixtures
  • Site restrictions
  • Site congestion
  • Reliability
Save Time, Save Money, Increase Profits


A concrete pump quicker and more precisely places concrete with less work than any other technique. A work that would take two and a half hours for five people to pour would take just one hour for three people to pump. Compared to truck dumping, contractors that pump concrete regularly report 50 percent labor savings.

Concrete pumping on site allows valuable staff to be reallocated to other tasks. Moreover, a pump can be used to discharge more ready mix trucks in less time, which means completing more jobs in a day.

Gordy's Concrete Pumping Service (Gordy's) was able to create a great platform for their company with a full line of Putzmeister boom pumps, run more efficiently for their customers and also reduce labor costs for their customers. This was especially crucial when, as of January 2007, putting the biggest quantity of concrete consumed on a Midwest site.

Site Specs:


  • 130,000 cubic yards of concrete pumped and placed by boom pumps
  • 11 different concrete mixes available per specification
  • Maneuverability and quick setup of the boom pumps allowed Gordy's to keep the project moving as efficiently as possible
  • The 63Z-Meter boom pump used on site is extensive — 203 feet 9 inches vertically and 190 feet 7 inches horizontally

  • Pumping Keeps Jobs Moving

Scheduling is one of a concrete pour's most critical aspects. On a busy work site, there is no space for downtime. Contractors with the right equipment efficiently place concrete, irrespective of weather, daytime or working conditions. Positioning and maneuvering equipment around a site can also be critical factors in determining the best concrete method of placement.

"For this project, there has been a whole year of planning and coordination between Webcor and JLS," says Vern Lee, Webcor's construction manager. "Because of Hollywood & Vine's massive footprint and opening date in the fall of 2009, it was a must have everything planned for a ' T. '

"In planning the three pumping stations and the impressive 1,110 meter (3,640 feet) below-grade delivery line system, every detail was scrutinized," says Willie Clemison of JLS. "The placement system includes both horizontal and vertical piping. Webcor and JLS had to ensure that the delivery system could transport concrete without any problem to any of the six placement booms and also allow three placement booms to place concrete at the same time." Putzmeister BSA 14000 was used to reliably pump the long distances required by this project.

Site Specs:


  • Curb-to-curb 4.6-acre footprint
  • Pumping and placing three different concrete mixes at any given time with six placing booms
  • 4,000- to 8,000-psi concrete mixes
  • 108,000 cubic yards of concrete
  • Placing booms on site have a horizontal reach of 115 feet 3 inches and vertical reach of 122 feet 8 inches
  • Six placing booms, pin towers and pumps
  • By providing more predictable unloading times, concrete pumps help mixer dispatchers. Due to the absence of interruptions and delays, the steady flow from the pump can also boost finisher productivity.

  • Unlike human resources, without complaint, pumps appear on time for work and never take a break for lunch. Backup systems can keep a pump operating through work completion in case of a issue, and wear sections are intended to be easily replaced.

  • Site preparation can be time-consuming, labor-intensive and unpredictable, hampering effective scheduling.

Eliminating the need to construct and relocate access ramps, concrete pumping can very often enable a complete work from one place while maintaining trucks ready for mixing safe at the curb. Also, pumps decrease the excavation time from 10% to 15% and facilitate backfilling.

Productivity of employees and safety


Not only does concrete pumping make a concrete pour more convenient and consistent, it also improves safety at work. Ready mixing trucks are kept at the curb, away from embankments, excavations and other dangerous obstacles, so that concrete can be placed exactly where it is needed.

Moreover, a concrete pump decreases workplace congestion better than most other techniques, enhancing work effectiveness and safety. Less dangers and a more ergonomic process are advantages that can lead in less sick days and a smoother running company for on-site staff.

A Quality Job Time After Time


Labor and time savings mean nothing if the quality of concrete placement does not meet expectations. For years, contractors pumping concrete have produced superior quality while reducing costly callbacks. Direct placement of concrete without re-handling also improves concrete quality.
In addition, concrete pumping does not require special mixes for optimum quality. A concrete pump will handle desired slumps and eliminate the need for excess water that can result in concrete cracking.

High-Rise Efficiency
The tallest buildings built in the past decade were pumped, even in excess of 1,900 feet high. Pumps can also achieve capacities in excess of 150 cubic yards per hour. Whether at ground level or on an impressive skyscraper, pumping concrete is the versatile and convenient way to get the job done right.

Going the Distance
Boom pumps are able to navigate up and over barriers as well as into confined spaces with other techniques to produce outcomes that are not feasible.

Furthermore, pumping concrete can also be a function of the distance to be conveyed to the material. Tunneling and mining are two excellent instances of when it is not possible to ignore the benefits of pumping.

"The BSA 14000 pumps 2,800 feet via slick line for the concrete lines of the North Avenue Tunnel," says Darrell Liebno, assistant project manager for Atlanta CSO Constructors (ACC). "The high pressure range of 3,190 psi and the high production quantities of 133 cubic yards per hour have significantly benefited us, considering the lengthy distances that the project requires the concrete to be placed." "The electrically powered BSA 2109H is rail-mounted, enabling high mobility in the Clear Creek Tunnel," adds Adam Stremcha, ACC project engineer. "Using electricity, this machine also offers zero emissions in its underground environment, making it environmentally friendly."
Site Specs:

  • Atlanta's largest tunneling project
  • Two tunnels will have a combined length of 43,800 feet and are anywhere from 160 to 320 feet below ground level
  • Concrete is delivered above and below ground by trailer pump and tunneling concrete placing equipment
  • 120,000 cubic yards of concrete pumped
  • 4,000-psi concrete mix
From small trailer-mounted pumps to powerful line pumps and longest truck-mounted boom pumps, concrete contractors have a wide range of options for numerous applications, including:

  • Mat pours
  • Footings
  • Indoor pours
  • Slope paving
  • High-rise buildings
  • Mid-rise buildings
  • Residential pours
  • Light commercial
  • Industrial
  • Bridge decks
  • Post tension slabs
  • Tunneling
  • Pools/shotcreting
  • Patios

Concrete pump manufacturers such as Putzmeister America work with clients to determine the most suitable placement technique based on a project's full scope. Beton pumping provides effectiveness, quality and ultimate advantages from housing foundations to the highest structures in the world.
