Although the Trojan Color Sealer is an all in one stain and sealer system, we do have many Acid Stain Professionals that use the clear Trojan Masonry & Concrete Sealer after applying their acid stain (once pH neutralized) to the concrete floor.

The below photo of Trojan Masonry & Concrete Sealer applied to acid stained concrete was provided by Mark Bighley Construction from Silver City, NM.

Why do acid stain professionals use Trojan Masonry & Concrete Sealer?


No Surface Residue! 

Unlike topical sealers (silicone, acrylic, polyurethane, etc), Trojan is a water-based, penetrating polyester concrete sealer that does not leave a surface residue. It instead fills the pores of the substrate leaving a matte to very low gloss (only on indoor, hard trowelled concrete) finish. Our sealer will not wear away as it hardens and bonds to the surface into one solid mass.

Although topical sealants provide a nice shine they also are a maintenance issue in themselves as they easily wear away, especially on outdoor projects where weather, UV and walking/driving takes its toll. Topicals can also be slippery when wet, unlike Trojan, which will not change the friction coefficient of the surface. Slippery surfaces are accidents waiting to happen.

Extra Surface Protection! 

Some acid stain professionals will apply Trojan Masonry & Concrete Sealer first and then a topical for the gloss finish, as they realize that clients may not maintain the topical with the reapplication requirements through the years. Therefore even if the topical has worn away, Trojan will still be left to 'lockdown' the acid stain from deterioration, still provide stain/spill resistance as well as easier maintenance since nothing will absorb into the concrete.

Safe for inside and outside use! 

Trojan Sealer is a non-toxic and low VOC (volatile organic compounds), unlike solvent-based sealers. Therefore you can safely use our sealer indoors or outdoors. You and your workers won't be breathing in harsh chemicals or contributing to environmental issues.

Eco-Friendly. Non-glossy. Resistant to yellowing from UV rays! 

Many acid stain clients want a 'natural look', non-glossy finish. Trojan provides this and will not yellow under outdoor UV light unlike traditional topical sealers.
