Does the MORTEX® coating need to be protected?
Although the MORTEX® product is waterproof in its mass, it behaves like most natural stones (microporous surface). Therefore, a protective finish for stains (wine, grease, etc.) is recommended indoors: varnish, oil, oil-wax, water repellent, etc.

In all cases, we recommend that you carry out tests and samples beforehand in order to validate the appropriate finish and protection.
