Dulux Weathershield Cobblelock 10L Paint is a high-quality decorative coating for exterior walls. It is formulated for professional use; being easy to apply and has excellent opacity.
For exterior jobs where you want dependable protection with a softer, contemporary edge, the Dulux Weathershield Cobblelock 10L delivers proven trade performance with a modern neutral finish. Cobblelock is a versatile mid-grey tone that works just as well on new builds as it does on renovation projects, giving a clean, balanced look that complements stone, brick and contrasting trims.
Formulated for exterior masonry, this high-performance, water-based paint is built to handle tough Irish weather conditions. Its advanced acrylic resin technology offers excellent flexibility to help resist cracking and flaking, while built-in mould and algae resistance keeps exterior walls looking fresher for longer.
With strong hiding power and a smooth masonry finish, Cobblelock provides reliable coverage across large surface areas — ideal for full house exteriors or boundary walls. Easy to apply by brush, roller or spray, it’s a straightforward option for both professional tradespeople and capable DIYers who want a job done right.

TJ’s Tip:
Don’t skip the prep. Remove loose material, treat any mould or algae, and make sure the surface is clean and fully dry before painting. Two even coats will give you better durability, richer colour and longer-lasting protection — especially on new render or previously unpainted surfaces.
