Got Timber Stained Furniture You’d Like Painted?
Step 1 – Difference Between Paints & Stains
When painting wood, you need to know there is a distinct difference between timber stains and paints. Paints cling to the surface of the wood, whereas wood stain soaks into the wood grain, turning the wood itself a different colour, not just the surface. That’s why it’s a lot easier to strip paint off a surface and it can eventually chip away, whereas a wood stain can’t.
Step 2 – Prepare The Timber Surface
Before any paint can be applied, we need to use various grade sandpapers or scouring pads on the entire area of the timber stained surface to sand back to a smooth non glossy surface which will allow the paint to adhere to it.
Most timber stains are finished in a protective clear coating of varnish, lacquer or polyurathane which is smooth and glossy and the paint won’t do very well at sticking to it.
Perhaps at first it might look ok, but in a short period of time the paint will start to chip and peel off. So it’s very important before you start to paint over stained wood, it is sanded back thoroughly to a surface where the paint will stick to it properly.
We don’t need to completely remove all of the stain, we just need to take the shine off of the surface. Then we vacuum the dust particles and wipe the surface clean with a moist rag called a tack cloth to remove any ultra fine particles of dust.
Step 3 – Apply The Primer
It is important to apply a primer first before painting over stained wood otherwise the paint won’t adhere properly, as well the primer prevents the colour of the stain from seeping through and showing up under the paint.
We use a solvent based primer and apply an even coat over the entire area to be painted and allow to dry thoroughly. Once dried, we give the surface a light sand making sure not to sand the primer off, then using a damp rag wipe the dust off again.
If you are painting over a rather dark stain then the primer can be tinted to match the colour of the paint you intend to use which will make sure the paint covers well and doesn’t show the stain through underneath.
Step 4 – Apply The Paint
With the gloss coats we can use either a regular house hold solvent based paint with a hardener additive added or we can use a more expensive but harder wearing and better finish two pac polyurathane paint. All of which is available from your local paint store. At Rags n Rollers we get our paints, primers and materials from our local Inspirations Paint and Colour store at Oxenford.
