Features & Benefits
Ideal for:
- Sealing and filling of interior gaps and cracks where movement can occur, such as those between plasterwork and window and door frames, skirting boards and architraves
- Use prior to painting or papering to prevent unsightly cracks developing later
Limitations
- Among others not recommended for continuous water immersion and not for use on PE, PP, PTFE, PC, PMMA, soft plastics, neoprene and bituminous surfaces
- Painting over with highly filled emulsion paints can cause cracks in the paint film. Adhesion tests prior to application are recommended
- It is the user’s responsibility to determine suitability for use
Cold Weather
- Generally, caulk should be applied in warmer weather, ideally above 5°C
- If you do need to apply it try putting your tube in a bucket of warm water before use to bring it up to the right temperature
- If it is stored in a garage or van, bring it inside the house the night before use so it can warm up
- If caulk is applied outside of the temperature range it won’t flow as well out of the tube, won’t sit right in the joint and won’t tool as well.

Questions
Question about the product
David on 2024-09-29 12:28:34 | Question:
Can I apply this product like normal caulk, so clean and tidy up the line with water, or is it more like silicone to apply and clean up? Is it also available in dark grey/black? Thx |
Answer from Rawlins’ Technical Team:
As this product is water-based, it would be similar to a regular Builders Caulk rather than silicone based, meaning it can be cleaned with clean, hot water. Unfortunately it is only supplied in White. | |
