Tips for Painting Over Shiny Surfaces
If you have ever tried to paint over shiny surfaces you know it can be difficult. This is not something that you can do with just any kind of paint. A shiny surface requires that you either paint with a primer or you sand the surface with sandpaper so you can have a dull surface to paint on. The shine means the paint is non-porous and the new paint doesn’t have any nooks and crannies to hold onto. Sanding the surface smooth gives the new paint or primer some porosity on the surface to grab.
Today it is not always necessary to scrape and sand a shiny surface because there are certain primers that will allow you to apply a coat directly to the shiny surface and then apply your regular paint coat. A high-adhesion primer will stick to the shiny surface acting like a double-sided tape between the shiny surface and the top coat of paint.
Before you apply a primer you will need to make sure that your surface is clean and dry. This will mean that the coat that you put on will be sure to go on smoothly instead of having debris going onto the wall along with the primer coat.
The right primer will paint over the shiny surface and adhere so your interior paint can go on top of it smoothly. Without a primer your paint brushes will slide over the surface and the paint will not stick to it.
There are many shiny surfaces like vinyl, glossy wood paneling, cabinets or tiles that will require primer before you do anything else. By using a primer you create a fresh canvas to work on so that you can choose whatever color you want next. Sometimes having a blank white wall will create many possibilities that you may not have thought about in the past.
Why A Primer Is Important
When you have a glossy surface a high quality adhesion primer will adhere well and create a sealed surface so that the color you put on top will be more uniformed in color. If you are painting on a surface that was painted before, using a primer will also stop the other color from shining through. A primer should also be used when you first move into your home and there is a flat paint that was used by the builder for your drywall. The use of a primer in this case will seal this porous surface.
Using a primer means that you will use less paint and create a more consistent and even finish. A good rule of thumb is to tint the primer to the color of the paint you are going to use so that when you apply the topcoat you will only have to use one coat.
In most cases the top quality Benjamin Moore Superior Fresh Start Acrylic Primer will be an excellent primer to paint over your glossy surface.
When to Use Sanding
It never hurts to sand the glossy surface dull, but there are times when must sand before you put on the primer. This would be when you have a surface that already has some defects on it from previous paint jobs. Areas where there is a heavy build up of paint or where you see streaks where paint ran down the wall will need to be sanded before you put the primer on.
