Types of Stone Sealers
If you’re to seal your countertop, you should know about the sealer types and their uses. They can be divided into different types from a different basis.
Solvent and Water Based: These names are based on the carrier of the sealant. In a solvent-based sealant, the polymer molecule gets dissolved into a solvent, where they get dismantled in a water-based solvent. Solvent-based sealers are also known as impregnators, last longer than water-based ones.
Penetrating Stone Sealer: They penetrate the surface of the stone and block water and debris from entering into it. These products get absorbed by the stone. They keep the stone breathable by maintaining their porosity and letting them escape the water vapor.
However, they are not effective against a salt attack. They are better for exterior use and thick, smooth, or polished stone types such as marble or granite. They can either be solvent or water-based.
Topical Stone Sealers: They sit on the surface and create a protective film on the top of the stone. They prevent water damage and staining by repelling moisture and create a barrier against dirt or oil. It has a sacrificial layer that gets affected by debris so that the material beneath remains unharmed. Most of the topical sealants are water-based.

Frequently Asked Questions (FAQs)
What is the difference between sealer and impregnator?
When we use a sealer over stones, they create a layer that protects the stones from other stains and dust and others. In the case of impregnator, resins are mixed with water or solvent. So, when we use this, the solvent or water evaporates, creating a barrier to stains.
What is stone sealer made of?
Modern topical stone sealers are made of polyurethanes, natural wax, or acrylics. Penetrating sealers contain siliconates, fluoro-polymers, and siloxanes. It repels water. Impregnating sealers are made of silanes.
How Often Should You Seal stone?
There are no exact time limitations, as different stones have different mineral compositions. However, Granite natural stones need sealing every 3-5 years. Shower grate stones need sealing every 6 months to 1 year.
How Can You Tell If the stone Is Sealed?
Pour ¼ cup of water in a small area. Wait for 5-10 minutes and wipe it off. If the water doesn’t get absorbed or the surface on which you poured the water doesn’t show any discoloration compared to the other, then it’s already sealed.
