Whitson’s primer is a fully water-based paint product, suitable for timing to problem substrates such as old oil-based paints, stain, varnish and uPVC. I suppose if I had to liken it to an existing product, it would be Zinsser Bullseye.
The adhesion of Whitson’s water-based primer is the best I have found, even on keyed oil gloss/varnish and also manufactured products.
I use it now on all my kitchen refurbs. It dries quickly and allows for more than one coat in a day, which always helps! The opacity is also very good and after only a few hours easily passes a scratch test.
The only negative I have found is it’s not always readily available, so tend to keep a little stock in case.
One question I would have for Cait Whitson is, which water-based gloss am I best to use over the top of her primer?
