3C Sealants

Introducing....... 3C Sealants a brand dedicated to high quality, experience-backed mastic sealants from us 'County Construction Chemicals' (hence the name, 3C get it? :-)) 

After many years of supplying market-leading, trusted mastic sealants from the biggest names in the mastic sealant industry, we strive to advance with the ever-changing market, thus, we're now offerering a hand-picked selection of high quality sealant products ourselves, using the very best materials, keeping stocks high and providing our usual high standard of service, in a helpful and professional manner. 

With our great reputation, experience and vast knowledge of the mastic joint sealant industry, we thought it was about time we had our own brand, hence the introduction of... 3C SEALANTS

You can purchase all the available 3C Sealants products right here on this page.

We're pleased to anounce that Craig Phillips and his wife Laura have partnered with 3C Sealants as brand ambassadors under their Mr & Mrs DIY moniker.
