Questions about Caponi – The Epoxy Grout Sealer?
We have answers.

Does Caponi come in colors?

Color is premixed in ‘part A’ with the pigments and we have over 40 colors.

Does Caponi have a smell?

Yes. We added a lavender fragrance to Caponi to mask the chemical smell. Caponi is a solvent base sealer..

How long will we have to apply Caponi since it is a two part catalyst?

Working time can range from 3-4 hours to apply.

Can Caponi be scrubbed with a grout brush?

Caponi is the only epoxy grout sealer that can be scrubbed.

Caponi is thick, is there a way to thin the product?

Caponi is formulated with high solids to make the sealer the most durable. We have Alco thinner which will thin the product, not recommended to thin in shower or underwater applications.

Can Caponi be used on non-sanded, sanded and epoxy grouts?

Of course. Caponi bonds to epoxy grout with its 1283psi adhesion.

What do we use to clean Caponi off the tiles?

Wipe the sealer off the tiles as you go with your finger (wearing latex gloves). Use the Alco thinner to clean up any residue that will not come off.

How do we dispose off Caponi?

Pour the left over sealer, back in the aluminum bottles, and dispose in trash. Caponi will harden within hours and transform to a solid product.
