LCETED TRIVIA
Why Do We Use Wall Putty?
This will fill in minor cracks and surface defects. The use of wall putty before applying paint helps to achieve smooth, balanced, finished and stunning surfaces for all types of paints. The use of the putty gives the paint a smooth surface, which enhances the hiding ability of the paint.

STEP 3: 2nd Coat Wall Putty

Purpose of primer

Primer painted wall can increase the durability of the paint and save a great deal of cost savings.

Primer, true to its name, serves as the primary layer of the painting system. The purpose of the primer is to provide the adhesive surface, taking the next coat of paint. Ideally, the primer will stick to paint, wall or any other surface.


Primer, in short, does a very important thing, which is why it is important to use a primer before painting. It improves paint adhesion, thereby enhancing the durability and durability of paint filling

Is 2 Coats Of Paint Enough?

Expect some surfaces to be twice as long with the second coat! Two coats of paint are always better and more professional than the one. The best paints sold by the best paint dealers recommend a two coat system. You get a long warranty with two coats of paint


PROCEDURE FOR INTERIOR WALL RE-PAINTING:
Surface Test: this is the most important part before you start painting. In surface testing, we must eliminate seepage, dirt, oil fatigue, paint imprint by using a variety of equipment such as cloth, sandpaper, plaster, and blades.

Sanding On the faulty surface, I mean a piece of paint that peels, dirt, tension and cracks

Putty: Apply putty to fill the gaps of the needle, tv wall mount, AC mount, cracks on surface and patches. Wait for the putty to dry. Approx 3–4 hours.

Sanding after putty: Do another round of sanding after putty dry, this helps to level the surface

Primer: This is not mandatory for re-painting of the existing colour. This is mostly applicable for fresh painting or colour change

Paint: Do one coat of paint, if you are not satisfied with one coat, Go for another coat.
