## Questions & Answers

**Q: Can this be applied in low temperatures**
A: Yes

**Q: Will it stick to concrete wall**
A: This product is very versatile and will definitely stick to concrete. The only negative i have to report is that it does not stay brilliant white takes on a more a dull off white colour. So although functional for sanitary finish i usually suit another sealer over the top of it.

**Q: Can this be used to stick two pieces of marble together?**
A: I’m afraid I can’t give you a definite answer, however I have used this product to bond to pieces of old steel together with very satisfactory results.
