Kurumbidza Kunoshanda
If you need deeper penetration, first protect resin flow: use the correct low-viscosity system, control temperature, minimize mixing-to-infusion delay, and confirm the equipment is leak-free. If bubbles remain, investigate air sources before increasing vacuum. If infusion is uneven, examine the stone and flow path instead of assuming the epoxy is defective. The most reliable process is the one that repeatedly gets resin into the right internal defects before gelation—and then cures strongly enough for the slab to survive the next production step.
Need to Test Vacuum Infusion Epoxy on Your Stone Slabs?
Stone porosity, crack structure, resin viscosity, working temperature, vacuum equipment, cycle time, and finishing requirements all affect infusion performance. Test the complete process on representative marble, granite, or engineered stone before bulk ordering.
