Pratt & Lambert Multi-Purpose Waterborne Primer
This primer, from Pratt & Lambert, is specifically formulated so that it can be used both indoors and outdoors. It bonds extremely well to almost any substrate, including such difficult surfaces as masonry, aluminum and PVC pipe. Please note that some of these surfaces may require special surface preparation for optimum sealing. Another difficult surface that it works extremely well for is repainting over existing high-gloss paint. It is a high pigment, stain hiding primer, which eliminates the need for a separate stain blocker. Fast drying, it can be top-coated with both latex and alkyd paints.
