Sand down the final finish with a 220-grit foam sanding pad, and then add another layer of General Finishes High Performance PolyurethaneTopcoat. Apply liberally than you did previously without heavy back-brushing.

Let the topcoat self-level a bit - it will tighten down as it dries.

If it's above 80°F or if the humidity is less than 70% in the space you're working, we recommend adding 10% GF Extender to the topcoat to improve open time.

It is normal to see a bit of stain on the brush when applying the first coat of topcoat. Topcoats often pull a bit of color on the first pass, but good preparation will minimize this.

To prepare open grains woods such as raw Oak for a water-based stain, we recommend sanding with 180-grit followed by no more than 220-grit sandpaper.

Enduro Clear Poly is designed for professionals that routinely spray their finishes. High Performance is formulated for the retail market so it can be sprayed or hand applied.

Vinyl or paper veneers can be often found on the end returns of lower price-point cabinets. We cannot guarantee that our paints will adhere well to a paper veneer - we have no idea what the actual material is or what adhesives were used to apply the veneer to the surface. The resins and additives in our paints may break down the adhesives used for the veneer.

And Milk Paint does NOT adhere to vinyl.

This is a guesstimate as GF cannot assist with the performance of another manufacturer's product used in conjunction with our own finishes.

It looks like Annie Sloan Chalk Paint is absorbing some of the topcoat because it is so porous. High Performance does not streak over a sealed surface when properly applied. Most likely the chalk paint is so dry it is pulling some of the solvents away from the High Performance, causing an uneven finish or the appearance of streaking. This happens on the original powder Chalk or Milk Paints also.

The term for a cloudy, milky appearance in the finish is Blush. There are three causes:

     1. The most common reason is an incompatible stain. For example, using a water-based topcoat over an oil-based based stain. When the top coat is applied, the oil in the stain seeps up through the finish and reacts with the acrylic causing a chemical blush.
