Sound Floors Underlayments never leave you hanging out to dry.
That’s because our full line of pumped FIRM-FILL Gypsum Concretes are easily installed and set in just 90 minutes. Enough time for a long lunch, then back to work. With no downtime waiting for the floors to dry, construction traffic can proceed the next day and when properly ventilated, the underlayment will achieve its ultimate strength in 10-14 days. With our quick drying floor underlayment products, Hacker Industries and our Licensed Applicators do our part to keep construction projects on schedule.
