Waterproofing with Impregnation Sealers

Solvent vs Water Based Sealers

What is an Impregnation Sealer?

An impregnating sealer is a type of sealer that penetrates into the pores of a material (such as stone, concrete, or wood) and chemically bonds with the substrate, creating a barrier that repels liquids and stains from penetrating the surface. Impregnating sealers are typically used on porous surfaces and are designed to protect the material without altering its appearance or texture.

On the other hand, a regular sealer is a surface coating that is applied to the top of a material to protect it from stains, dirt, and other environmental factors. Unlike impregnating sealers, regular sealers do not penetrate the material, but rather sit on top of the surface to form a protective layer. Regular sealers come in a range of finishes, from glossy to matte, and can be used to enhance the appearance of the material.

In summary, impregnating sealers are used to protect porous materials by penetrating and bonding with the substrate, while regular sealers are used to protect the surface of materials by forming a protective coating on top.

What is the difference between water & solvent based impregantion sealer?

Water-based impregnating sealers are made with water as the main carrier, and they contain a lower amount of volatile organic compounds (VOCs) than solvent-based sealers. Water-based impregnating sealers are generally considered to be more environmentally friendly and safer to use than solvent-based sealers.

Solvent-based impregnating sealers, on the other hand, are made with solvents as the main carrier, and they contain a higher amount of VOCs than water-based sealers. Solvent-based sealers are typically more durable and long-lasting than water-based sealers, and they may be better suited for use in high-traffic areas or areas exposed to harsh weather conditions.

A key difference between water-based and solvent-based impregnating sealers is their application process. Water-based sealers typically require more coats and longer drying times than solvent-based sealers. Additionally, water-based sealers may not be as effective at repelling certain types of stains as solvent-based sealers. Solvent-based sealers are generally more reactive with any other coatings that have been previously put on the a surface while the water-based are unreactive.

Ultimately, the choice between a water-based and solvent-based impregnating sealer will depend on the specific needs of the project, including the type of material being sealed, the environmental considerations, and the desired level of protection, durability and reactivity.
