    Hi there, it won't have quite the same depth without the white wash being able to penetrate the wood because you're going over polyacrylic. However, I think it would still look just fine!

    As Grandma said in her post, whitewash will still work but will not "soak" into the piece. Use the whitewash to get the look you want, then seal it with a clear sealer to maintain the look.

    Hello. Poly acrylic is occlusive sealer. Whitewashing over it might work but look a little different than over painted surface. Likely the white wash will float on top of the sealer.

    Since it is water based, you should be able to follow normal paint process. I always prep by 1 of 3 steps: TSP, sanding, or fine steel wool. I clean after sanding or wool with denatured alcohol. Then prime if needed and paint. Depending on your current finish and what you want for the final product, you could do a 50/50 paint/water solution and just go with TSP and then apply the thinned paint.

    Water-based polyurethane has a slick finish which looks keeps other products from adhering to it. To prepare the polyurethane to accept paint, first wash it down with a grease-cutting detergent and water and dry it well. Next, scuff the polyurethane surface with sand paper.

  • Strip or sand the piece first, then you could add the new finish on top.

    Sand it to rough it up first

  • Polyacrylic as in the sealer? If so, your best bet is to do a dry brushing over it. Any water based paint will likely bead on the surface. Otherwise sand the finish off and whitewash from there.
