Getting a perfect wall finish requires expertise of sorts. Many people skip the step of applying undercoats on a while repainting house walls. As a result, the final finish is uneven and blotchy. Even the contractors may not give you correct advice to go for undercoats if your budget is constrained. But these undercoats prove a good investment in the long run because the paint on your walls will stay fresh and intact for a long time and wont’ chip off easily.
Products like wall putty, acrylic primer, cement primer (water based or solvent based) are undercoats that give good adhesion to colour among other things. For eg, acrylic water based putty is used for patching up cracks, blemishes and holes on masonry surface. It is specially formulated for levelling of minor surface irregularities up to 3-4mm. However, it is recommended for internal application only. If your wall is affected by mould, we suggest you to treat it with 1 per cent Surface Treatment Chemical (STC) before applying any undercoat. After it dries off, apply putty using trowel, putty knife and leveller.
Primer, on the other hand, is used on surfaces which are fairly even. If there are only hairline cracks on the wall, ready to use wall fillers can be used. The purpose of primer is to basically give better adhesion to the paint on the surface. Correct application of primer ensures better quality and durability of finish coat. It is applied using a brush. Thus these undercoats can do wonder to the final finish of the wall. If the adhesion of the topcoat is good, then paint won’t chip off easily and your wall can look good for a longer period of time.
