Environmentally-Friendly, Healthy, and Safer Adhesives, Grout, and Waterproofing Products
As consumers have become more environmentally conscious and concerned about the impact of chemicals on their health, they’re being more selective about the products they buy. One area that’s getting a lot of attention these days is Volatile Organic Compounds (VOCs). VOCs emitted during the application process can lead to short-term and long-term adverse health effects, according to the EPA.

The Zherorisk® platform is a technology projected into the future with the aim of developing an innovative generation of eco-sustainable building materials, at “zero risk”.
When using adhesives and coatings, it can be a concern for installers. Some products can continue to give out low-level VOCs for years, which can cause problems for homeowners.
‘The use of sustainable, environmentally sound materials offers healthier alternatives for installers, consumers, and the planet while also contributing to improved indoor air quality and building wellness,” said Curt V. Rapp, founder and CEO of Tile Doctor.

ZHERORisk Products
That’s why so many contractors, installers, and homeowners have turned to the Tile Doctor’s line of ZHERORisk products. The ZHERORisk line of products is environmentally-friendly and does not emit VOCs (volatile organic compounds). They meet the strictest tolerances for indoor air quality.
The ZHERORisk technology was originally conceived by Litokol as an answer to the European Union’s efforts to reduce the corrosiveness of installation products. The project, called ZERO (Zero Environmental Risks in Our Buildings), led Litokol to develop a suite of products, including:
- Litokol Aquamaster Waterproofing
This is a solvent-free coating with a liquid membrane to use in waterproofing moist environments in both interior and exterior settings. It works indoors or outdoors. Unlike other products, it doesn’t need reinforcement or sealing straps to protect edges. - Litokol Litoelastic EVO
This is a two-part adhesive designed for ceramic tiles, glass tiles, and natural or composite stone. The high-performance adhesive that literally does it all. - Litokol EpoxyÉlite EVO
An acid-resistant epoxy mortar/setting product used for the installation and grouting of ceramic and glass tiles on indoor and outdoor floors or walls. - Litokol Starlike EVO
The only product in the world that can be used in three different ways: as a grout, as an adhesive with no vertical slip, and as a decorative wall finish.
Starlike grout is the most environmentally-friendly, high-performance grout on the market. It’s the safest product for installers and homeowners. It can be used as grout, mortar, or even a wall covering. The Tile Doctor offers a full line of Starlike products for indoor and outdoor use, including stunning colors and finishes.
