Why do we Insist on Thorough Deep-Cleaning before Sealing?

As natural stone surfaces are porous, they tend to absorb water, moisture into their pores and remain damp. This dampness inside provides excellent breeding grounds for mold and mildew. Even stains penetrate deeper inside and form dense and stubborn.

Best Floor Tile Grout Cleaner - Imperia Deep Clean

You need to first use a deep-penetrative and robust cleaner to clean such stains and mold from the root. The best cleaner with a deep-soaking quality is Imperia Deep Clean, eliminating all the deep rooted stains and mold. Once your natural stone floor, shower or countertop has been cleaned, sanitized and prepped using this cleaner, you can proceed to sealing.

How does Sealing Protect your Natural Stone and Grout?

We have already discussed the porosity factor above. Stone floor sealing, when done with the right water-resistant products forms a protective coating on the surface, thereby preventing further water absorption, and subsequent mold and mildew breeding.

We generally recommend our customers to seal their grout separately before sealing the tile. This step seals the grout and prevents moisture present inside to give birth to mold, which eventually gives a hazy appearance beneath the tile sealant. Grout sealing should be done with Caponi – our best titanium made solven colored grout sealer that can be shaded in more than 40 color options.

Furthermore, tile sealing is also important because you cannot control or avoid food or beverage spills, leaks and other such dirt on the surface. Such spills seep in directly into the unsealed surface, making it favorable for mold breeding.

When you seal your natural stone surfaces such as travertine, marble or slate, you also protect them from chipping off easily.

Moreover, some natural stone surfaces like slate also shed dust. An unsealed slate tile starts to look worn out and faded in a few years owing to repeated shedding of dust. When you seal slate stone, you prevent it from fading and it retains its lustre and sheen.

How to Seal Stone in the Best Way?

Now that you are convinced that sealing stone protects it from staining and preserves its beauty, we will introduce you to our best stone sealer.
