HOW DO I APPLY SURFACE TREATMENT?
Remove surface treatment (varnish or paint). Ensure surface is clean and dry and apply primer to the timber.
When dry, apply a coat of water-based acrylic varnish/paint (always follow the manufacturer's directions).
Apply the same method to the affected areas if the varnish/paint is damaged.
When you treat the wood, it is important to cover the gaskets to prevent varnish/paint rubbing off on the gaskets, as this will make the gaskets stiff/hard and spoil their effect.
