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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good First Impressions, Ready for Upcoming DIY Jobs *by on Reviewed in the United Kingdom 19 July 2026* I purchased this Everbuild EVB450 Builder's Silicone as part of a DIY project and, although I haven't had the chance to use it yet, I'm happy with the product so far.

Excellent stiction, decent working time (about 20 minutes on a hot day). Being transparent, cleaning excess off the wood and glass isn't essential, but it came off easily with a palette knife and spirit-soaked rag. Very little waste ### ⭐⭐⭐⭐ Good sealant *by on Reviewed in the United Kingdom 2 November 2026* Have used this before. Very good sealant. Handy to have. Easy to order.
