Clear Coat vs. S-1 Sealer

We carry two epoxy sealers, both of which will perform equally as a sealer. The differences are found in application and physical properties. 

1) Clear Coat is a low-viscosity, 100% solids, solvent-free epoxy sealer that cures to a clear gloss finish. It has a 2:1 (resin:hardener) mix ratio by volume and is best applied by the roll and tip method.

2) S-1 Sealer is a great alternative for a penetrating epoxy sealer. It is a 50% solids, solvent-based epoxy system that can be applied by brush, roller, or spray. This sealer has a 1:1 (resin:hardener) mix ratio by volume and offers a long pot life of 24 hours at 70°F. 

The mode of application, porosity, and material of the substrate may be a good deciding factor in choosing the best sealer for your project. If the substrate is very porous, you might consider using the Clear Coat for its higher solids and faster film build. The S-1 Sealer may not be ideal for materials that are not compatible with strong solvents (e.g. EPS foam, thermoplastics). However, if you prefer to spray, S-1 Sealer is the product to use.
