Donald Durham Rock Hard Water Putty
DURHAM’S ROCK HARD Water Putty®
is a gypsum-based filler – a powder – that becomes very hard when mixed with water. It never shrinks and has great bonding strength. That’s why so many people use DURHAM’S to fill holes and cracks in wood, plaster, furniture, stone, and concrete. Once DURHAM’S is set in place … it stays in place.
