Painting & Wallpapering/Prepping doors


Hello,  I have some 60 year old cabinet doors that are 3/4 in. Plywood.  They were stained and finished with varnish.  I want to paint these with semi gloss latex paint.  What is the best way to prep these first?  Thanks.


Obviously sanding and removing all loose material is essential but I don't think you will be able to apply a latex based paint direct to the varnish finish without it bleeding through.

Zinsser do a range of Primer sealers that will act like double sided tape keying to the substrate stopping bleed through and allowing sound surface for top coat. I would think that the B I N primer would be the product for Varnish.

Hopes this helps.

I can answer questions on all interior and exterior painted surfaces. Ranging from new plaster and woodwork to galvanised metal, rusty metal to exterior render stucco, All external timbers from solid oak to tannalised fencing. I have specialist knowledge on Flame Retardent products for Combustiable and Non Combustiable surfaces. Although some product knowledge of Car finishing I do not feel I have enough experience in that field to be able to offer knowledgable solutions.Colour queries are welcome but I have not got a design background and can only answer semi technical questions with regard to colour.
