## Questions & Answers

**Q: can i use this to seal an outside tap...copper pipe, brass backplate, stone wall**
A: I don't see why not, another alternative if there is a gap and you are able squirt builders foam into the hole in the stone wall round the pipe until it will take no more and then bind some tape round where the foam is starting to bubble out, this will ensure that the foam expands it goes further along the hole and stabilises the pipe. after 33 - 40 minutes any surplus on the exterior can be cut off with a knife and you will have a solid well supported pipe.

**Q: What shade of grey is it Paul? Thanks, Paul.**
A: A bit brighter than cement. I used it for expansion joints on patio.

**Q: Hi. can this be painted over once dry. Thanks**
A: I don't know sorry. I assume the paint would not stay on as it's really rubbery.

**Q: Would this work for sealing around laminate flooring?**
A: Hi. 450 Builders Silicone should not be used where it can come into contact with oils or plasticisers so may not be suitable in this application. We would recommend Everbuild Timber & Laminate Sealant for this.
