Can I use Universal Wood Treatment and Preservative over painted, varnished or waxed timber?

Unfortunately Wood treatments such as Permagard Universal Wood Treatment and Preservative all need to be applied directly to the timber surface and therefore you would need to strip all coatings back to the bare wood and apply the treatment for the product to be successful. You cannot apply this type of product over paint, waxes and varnishes.
