In the fourth step, you must sand the wall to ensure that all types of contaminants that may be on it are removed. If you can't get an electric sander, getting the job done right will take a little more effort. So, here's a tip: fold the sandpaper into four parts and make circular movements. That way, the process will be more straightforward.

Manufacturers already give dilution instructions in the can description. So follow them.
In general, you should pour the paint into a clean container and use potable water as the manufacturer recommends diluting the paint. Once that's done, you're all set for painting!
9- Application of paint
When painting, never sink the paint roller into the paint. Removing the excess in the paint tray and painting the wall in vertical movements is recommended. Always move the paint roller from bottom to top. This prevents the paint from running down onto the floor.

First, apply a coat of paint over the places where the plaster and plaster were applied. This will even out the absorption of the paint in these places and prevent the appearance of stains from these repairs on the finished paintwork. Please wait for it to dry and apply a coat over the entire surface.
10- Painting the corners
After the first coat of paint was finished, it was time to paint the corners. For this, you will need a brush. Carefully dip the brush into the paint and wipe off the excess. With smooth movements from side to side, paint the corners that are not yet painted.

Allow 3 hours for the primer to dry completely, including corner painting. With the wall dry, check for excess paint. If you have, use sandpaper to correct the imperfections in these places. Then apply the second coat of paint, leaving the wall uniform.
