Sulfur Capping Compound. The Sulfur capping compound features ultra-strong hot-blended flakes for guaranteed consistency from sulfur, mineral filler, and special components. This provides top performance, even for high-strength concrete tests. The sulfur capping compound melts quickly at 240° – 260°F (116° – 127°C).
FIRM-FILL® 3310. An innovative product that elevates gypsum concretes to an unprecedented level of unyielding performance. FIRM-FILL® 3310 floor underlayment's fast-setting surface rapidly eliminates water allowing for accelerated drying time and unparalleled levels of strength and finish over wood and concrete subfloors in new construction and renovation projects.
Poured gypsum concrete is beneficial for a few reasons: 1. Reduction in thickness. Poured gypsum can be poured at a minimum of ¾ in. (19 mm) instead of the 1-1/2 in. (38 mm) that light-weight concrete requires. 2. Poured gypsum sets and develops strength very quickly which can allow trade traffic to resume in as little as one day.
