What is the difference between ProxSeal 180 and ProxSeal 185? (What does solid content mean?)

ProxSeal 180 was our original high-gloss sealer and remains a reliable choice for stamped concrete and exposed aggregate. It contains approximately 21% solids (resin) by weight.

ProxSeal 185 was later developed with a higher solids content of 25%. A higher solids content provides a thicker film, similar to applying a heavier coat.

ProxSeal 185 is particularly well-suited for interlocking brick and paving stones, which are more porous and may otherwise require multiple coats. Many customers also prefer it for exposed aggregate. ProxSeal 180 is still recommended for stamped concrete.
