Questions
Question about the product
Andy on 2024-04-26 15:22:05 | Question:
Can I emulsion over Theormoproof Fluid or Thermoproof Original? |
Answer from Rawlins’ Technical Team:
This product is designed to be used as a fireproof penetrating fluid for porous internal wood, and if required can be over-coated using Thermoguard Smoke & Flame Retardant Dualcoat to provide a decorative finish. Thermoguard haven't tested with Emulsion based third party paints so advise against using anything other than the compatible Thermoguard Smoke & Flame Retardant Dualcoat. | |
