Frequently Asked Questions
Q: Will Pro Clamps work on textured or porous tiles? A: They are optimized for smooth, non-porous surfaces like polished porcelain, granite, marble, quartz, and glass. Ensure the surface is clean and dust-free before locking.
Q: How many clamps do I need for a project? A: A single 2-piece clamp set works great for standard seam joints. For long kitchen countertops, shower walls, or oversized slabs, using two or more sets side-by-side ensures perfect edge-to-edge alignment.
Q: Does it leave marks or rubber residue on light-colored stone? A: No, the non-reactive natural rubber pads are formulated to leave surfaces clean and damage-free.
