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 separation is a condition the paint industry calls "float." This is typical with specific colors, such as grays, because of the large variance in the gravities of the pigments required to create those colors. In gray, for instance, Ti02 (white) is 3.4 and black is 1.62. The lower density will float.

This phenomenon will not occur in colors with less variance in densities. Float is not unique to General Finishes products.

All bright white paint will yellow slightly with time, even without topcoat. You have probably tried to touch up white woodwork in your home after several years and noticed that the new paint is brighter.

But white and light paints can react if clear coated with a waterbased finish; water-based topcoats are reactive and may draw out substances in the wood such as tannins, dyes or unknown substances in existing finishes causing the topcoat to yellow. This is an industry-wide issue and can happen right away, years later or never.

Yes, you can. The resin systems for General Finishes Exterior 450 Topcoat and Milk Paint are the same.
