One of the essential steps when preparing for house painting in NJ is preparing the surface to be painted. Many painting projects are quietly sabotaged by failing to properly prepare the surface. When the surface is not made ready to receive paint it can cause peeling, cracking or bubbling. This is because the unprepared surface does not allow for proper adhesion and when the paint does not stick well enough it can trap air beneath it or simply not stick well enough to properly cover the surface being painted. It is essential to use the right type of primer and the right amounts of paint. Finished wood, bare wood and varnished wood all need to be prepared differently in order to complete a painting project which will last.

Preparing Wood that’s Already Been Painted

When looking at wood that has already been painted it can be very tempting to think that the surface is not in need of any preparation at all. But nothing could be further from the truth. Even though it has already been painted once, it will still some work to get it ready for another coat of paint. Get started by washing the surface thoroughly with just some soap and water and then rinse it completely so that there is no soap residue. Allow the surface to dry thoroughly and then gently sand it so that any loose paint chips are dislodged. This keeps them from poking out from the surface and messing up the new paint job. Before applying the primer, wipe the surface down with a damp cloth or rag to ensure that there are no paint chips or splinters. Use a primer that is the same as would be used on unfinished wood surfaces. The difference is that the primer only needs to be applied on the portions of the surface which has bare spots and bare wood is visible. Make sure that these areas are covered completely. After the primer has had adequate time to dry, it can be painted again.

Preparing Unfinished Wood Surfaces

Sometimes house painting in NJ entails painting wood that has never before been painted. Surfaces which are more weathered need to be washed, but this is not the case with unfinished wood. But it will take some careful attention to prepare the surface for painting. The unfinished wood needs to be sanded gently so that any small imperfections or splinters are removed. Then take a damp cloth and wipe the surface down real good to ensure that there is not any sawdust or grit left on the surface. The unfinished wood then needs to be painted using a primer. It’s okay to use either a latex based primer or one that is oil based and quick drying. The primer helps protect the surface of the wood and allows the paint to adhere to the surface much better. After the primer has dried, then spackle any dents or holes, apply caulk to any cracks and the get ready to paint.

Preparing Varnished Wood Surfaces

It’s important to sand varnished wood vigorously to de=gloss the wooden surface. This will make it rough and score it so that the surface will be somewhat uneven. This allows the primer to adhere to the surface more easily instead of sliding off. After sanding vigorously in order to de-gloss the wood, wipe the entire wood down with a damp cloth in order to remove grit, dirt and any scraps of varnish. After it’s been sanded, apply the chosen type of primer over the surface of the varnished wood. This will make it perfectly ready for painting later on. After the primer has completely dried, it’s okay to begin painting the surface.
