SikaSikaBond SBR+ Waterproof General Purpose Bonding Agent and Mortar Admixture – Water Resistant – Clear – 5 Litre

Definitely the builder's choice.Excellent value, I got 2 for less than the price of one at popular shops (Sc*refix & t*olstation).5 litre size perfect, it dries quickly leaving a waterproof barrier.The best quality and versatile for render, mortar and as a primer. High functionality and great quality.

Great sbr. Goes a long way and much cheaper here than screwfix

I used this to bond white pea gravel around a tree in the garden and it stops the gravel getting knocked onto the grass, it has went a tinge of yellow after approx 8 months

I used Sika Bond SBR+ for a DIY project, and it worked really well. It made the cement mix stronger and easier to apply. The consistency was great, and it helped stop the mix from cracking when it dried.Even though I’m not a professional, I found it really simple to use. Just follow the instructions, and it does exactly what it’s supposed to. It also improved how well the cement stuck to surfaces, which was really helpful.Overall, it’s a great product for anyone working with mortar or concrete. Definitely recommend!

Great price and value for money. But regularly, great product

Excellent adhesive. Best you can buy

Great product, worth the money. Makes mixing concrete and mortar better. I makes mortar a lot easier to manage.

Great price delivered following day, used many times before for making a cement slurry, perfect every time!
