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
Richly-pigmented, penetrating solvent-based primer.
Dries to a uniform flat finish.

upon the porosity of the surface.
