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

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!

This is a fabulous product. I had a big job to do to repair a failing render. Used this to prime masonry and also at every stage of cement render and patching instead of lime. Adds a velvet texture with great adhesion and makes mixture more easy to spread. Really glad I tried it!

Im amazed by this product, we've bonded quite well together

Great product arrived on time and good value

Great item and goes a long way.I needed something to bond my exposed bricks so this mixed 50/50 did the job. Easy to apply and veey god to work with, dries nice and clear and for the price real value for money.

Works well

Used on a outdoor re rendering job and seams to be a good product I will need a winter on the job to be sure

Now then, I am not a professional plasterer. I did my Hardwall first, allowed to dry (as time had run out) SBR’d it next day, allowed to dry. When I skimmed I kept getting horrible grit ruining my finish. I was perplexed as I’d been meticulous in cleaning before starting. On second skim coat I noticed that the ‘grit’ was in fact SBR crystals!!! Maybe I should have plastered over when tacky, but I never thought that this issue would have happened through letting it dry first. I was gutted and proper frustrated
