Frequently Asked Questions (FAQ):

Q: Can I use this undercoat with any brand of topcoat?
A: While this undercoat is compatible with most water-based and solvent-based topcoats, it is specifically formulated to work optimally with Sandtex exterior paints.

Q: Is sanding required between coats?
A: For the smoothest finish, a light sand between coats is recommended but not always necessary.

Q: Can it be used indoors?
A: It is formulated for exterior use, but can technically be used indoors where a tough, weather-resistant base is needed.

Q: Does it require a separate primer?
A: No. This is a self-priming undercoat, meaning no additional primer is needed on most surfaces.
