ABOUT FORMULA 131
Etch & Stain protective sealer for natural stone surfaces.
Properties
Formula 131 provides superior protection against both acid etching and staining. When independently tested by the Tile Council of North America (TCNA) against the leading aftermarket sealers, Formula131 has shown to be superior in the most important attributes required in a natural stone sealer stain resistance and acid etching. There is no product currently in existence that provides comparable protection.

Competitor Sealed Stone
Stain Test
Samples of honed white venatino marble were provided to the TCNA along with competitive sealers. TCNA personnel applied the sealers in accordance with manufacturer’s instructions. Seven stain agents (per CTIOA-72) were applied and wiped off after 3 minutes.
The results were then evaluated and graded according to CTIOA-T72 (a grade of 60 is required to pass; a grade of 70 is a perfect score). All competitive products failed after 3 minutes exposure. Formula 131 received a perfect grade after 24 hours exposure!
