Painting - Getting It Right

Painting problems can be avoided if the decorator would simply follow the paint manufacturers recommendations. This is mainly regarding correct preparation of the surfaces along with the application of the correct primers and or sealers, for all the various surfaces and substrates.

The use of primers and sealers may place an extra cost to the painting project, however the extra cost will be worthwhile as the lifespan of the surface being painted will be extended.

Modern building products require scientifically blended paint coatings which are formulated to deal with the fabrics porosity (suction) alkalinity and other important factors.

Plaster sheeting and Paper faced plasterboard, just to name a few require special needs and sealers to prevent possible top coats from peeling and or flaking off.

Paper Faced Boards
Due to its surface having a nap or fluff, a water miserable or water thinned sealer should be applied, which wets the nap and enables it to relax and lay along the surface.

The sealers special binders and other ingredients provide greater penetration into the face paper that gives good anchorage for the paint coatings, thus preventing possible painting defects.

If the decorator is considering hanging wallpaper to paper faced board then it would be advisable to apply an oil based alkyd coating to seal and protect the face paper. Failure to protect the papers surface will possibly result in it becoming wet and easily damaged.

Plaster Sheeting
Plaster type sheeting is formed in a type of mould thus the face of the sheeting is produced with a dense glassy finish. This smooth, dense facing tends to prevent normal water thinned coatings from penetrating into its surface which may cause peeling and or flaking. Because of this common problem it is advisable to apply an approved and recommended sealer to achieve the penetration required.

Once a sealer is applied the following paint coatings will spread with a lot more ease.

Harry's Tips
1) Before using a dry brush or roller sleeve in water thinned paints, dampen them with water. This will prevent clogging of the bristles in the brush or in the nap of the sleeve.

2) When washing water thinned paints from brushes and or roller sleeves, wash them in a bucket of water rather than directly under the tap. This will save lots and lots of precious water and money.
