HB42 Premium Decorators Caulk - White - 380ml - Box of 12

HB42 Ultimate Decorators Caulk – Box of 12 Cartridges (Trade Pack)

This box of 12 HB42 Ultimate Decorators Caulk cartridges is a practical bulk buy for tradespeople and decorators who work through caulk regularly. With 12.5% flexibility — more than double many leading brands — this one-part emulsion sealant moves with your joints instead of cracking, giving a seal that stands the test of time.

Once exposed to air, it cures into a durable, flexible finish that fills gaps wider and deeper than standard caulks, and can be overpainted in as little as 1 hour, so jobs keep moving without unnecessary downtime. Suitable for interior and exterior use, each cartridge includes a fungicide to help keep seals cleaner and mould-free for longer. It's CE marked and meets EN ISO 11600 F 12.5P, along with BS EN 15651 Type F-EXT-INT standards for perimeter frame and joint sealants.
