Putty is a white cement based powder used to cover up deformities in the wall surface. It helps give an even surface that takes up good polish in the form of paints.
Putty gives your walls a good finish
Every worthy builder and house owners who have made their own house know that the secret to having a great wall lies in the finishing of the same. Walls in concrete construction in an unfinished state have an uneven and rough appearance. There are cracks and holes and this makes them look ugly.
The way to finish the walls is through the use of wall putty. This is an indispensable item in building construction. If you have no putty, you have no great walls, only ordinary walls. One has to choose the best expert putty for walls. This pointing work on the walls prepares the surface to expel water and keep the paint from peeling. One may do the pointing with cement or with lime but preference is for cement pointing because the finish is better.
Use the right ratio
If you want a cement plaster of 6 mm thickness, one must take cement and sand in the 1:3 ratio. This will make sure that there is no water seepage and the finish is even and smooth. If you need a damp proof course, you must apply two coats of plaster to get 20 mm thickness.
Keep the putty work last
The trick to achieving a great finish is to first make sure that you have done all the electrical and plumbing work first. Then, make sure to complete the work in one day as otherwise the difference in the mixes could result in cracks or different textures in the wall finish.
Make the surface clean
To make sure of a proper bond between the wall surface and the plaster, you must clean it thoroughly with sandpaper and make it smooth. Remove dust and mortar using a metal brush. The wall needs curing for at least 15 days to ensure that it has enough hardness.
To keep the quality of the work at a good level, always use skilled masons to do the finishing work. Use good quality bricks that take plaster well. Before you begin plastering, wet the walls well so they do not absorb the water in the plaster. Before you plaster the wall, do the repairs for the cracks and leakages.
