Superior Stone Products Filled Polyester Stone Adhesive – Quart, Knife Grade, Buff
The Superior Stone Products Filled Polyester Stone Adhesive in buff knife grade is a pigmented, thick-paste polyester that gels in 3 to 5 minutes and reaches full cure in under 20 minutes when mixed with 2% to 4% white paste hardener (BPO).
Key Features
- Mixed with 2% to 4% white paste hardener (BPO); the hardener is sold separately as Superior White Paste Hardener - BPO in 1 oz and 4 oz.
- Gel time 3 to 5 minutes, full cure in under 20 minutes.
- Knife grade paste in buff. Superior publishes buff in both flowing and knife grade.
- One quart, one container - no two-part kit and no mixing tip needed.
- Buff is one of four published options in Superior's filled polyester line, alongside white, black and travertine filler.
Who Is This For?
Countertop and stone shops that want a fast-turnaround polyester in a buff tone rather than a clear one - the sort of work where the bond line is going to be visible and a warm color reads better than white. The under-20-minute cure suits a shop that needs the piece moved on the same shift.
What This Is Not For
Buff is a pigmented adhesive and it will read as a colored line. Where the joint should not show a color at all, the Superior Stone Products Water-Clear Polyester Stone Adhesive - Quart, Knife Grade is the clear-resin equivalent. This is also a fabrication adhesive rather than a setting adhesive; bonding stone or tile down to plywood, backer board, concrete or masonry calls for the Superior Stone Products E-1500-S Tile & Stone Setting Epoxy.
