Use of water based cement primer for walls

First, you see we have two kinds of primers. One is the oil based primer while the other is water based. The oil based is more durable but cleaning is hard. You will need turpentine, paint thinner, and more for cleaning. For this reason, many people choose the water based primer.

Use of cement wall primer

How many coats of primer should one use? It does not matter, one coat will suffice. The most commonly used one is cement primer water based for interior walls. If you want to get a better color match, tint the primer to the color of your wall. The wall needs to be prepped before you paint it.

The main reason for applying wall primer is to block the porous surface of the wall. This prevents the wall from appearing disheveled. It prevents the stains from showing and covers any discoloration due to moisture or fungus. The first step to applying the wall primer is to cover the jointing line of the wall with the windows, doors, HVAC fixtures and switches with painter’s tape.

Check and fill deformities

Inspect the wall for crack, holes, spackling compound, and grit. Use a putty knife to cover these deformities with putty. Allow the wall to dry. Then, use a brush to remove the dust from the surface of the wall. Keep drop clothes beneath the walls and move the furniture and other big objects out of the way.

Now, do the cut in to cover the edges where the walls meet the windows and doors. After this you can use the cement wall primer to cover the wall. Let the application dry for 2-3 hours at least. Then, it is ready for painting.

After the primer has dried, sand the bumps and use fine grit sandpaper folded into quarters to rub down the surface. Clean with a damp cloth; allow it to dry.
