Recommended Uses:
Cabot® Problem-Solver® Primer is a solvent-based, exterior primer specially designed to provide maximum performance through a faster drying and higher-hiding formulation. In addition to superior resistance to extractive bleeding and moisture problems, this 100% alkyd primer dries in a fraction of time compared to traditional linseed oil-based primers and facilitates the application of a quality finish coat within just a few hours. Cabot Problem-Solver Primer makes an ideal base coat for all types of solid stains and paints and will yield outstanding results on siding, shingles, plywood, and on both smooth or rough-sawn surfaces. It is also suited for application over previously oil-based stained or painted surfaces. Cabot Problem-Solver Primer is recommended for use on extractive-prone wood species such as red cedar, redwood, mahogany and fir. It is also excellent when applied to pine, cypress, spruce, and even pressure-treated wood. This product has exceptional adhesive properties and can be applied immediately to new, dry, unseasoned, mill-glazed (smooth) siding.

Richly-pigmented, penetrating solvent-based primer.
