Sika SikaMix Frostproofer and Hardener - Chloride Free Liquid Admixture for Accelerated Setting and Hardening Time of Concrete and Mortar – 5 Litre

Used this product so many times, you don't have to wait for warmer weather, instant concrete, but obviously not in rain needs cover.

Mixes well and does a great job for hardening and frost proofing - used it in a small bridge over a small watercourse no issues

thank you amazon and drivers great service order same with tool station let down 3 days 1 click with amazon i got it 24 hrs later what a great company merry christmas all brian

I’ll be honest I’m not an expert on diy but during the summer we repointed our walls and it was horrendous so when it came to do the other side of the house, I thought we’d try this in the cement and I so wish I got this in the summer. Made the cement more workable and left a better result. It’s does set quicker than just cement, can’t comment of frost proof yet as it’s just starting to get really cold. Overall I highly recommend this

Happy

I was hoping would help with aggregate MOT combination and mechanical compacter to give a hard, compact finish to a sub base. Probably not the best use to review the product as really difficult to determine if helped. As an accelerator didn't really see a difference between using this and using water. As a frostproofer too early to tell.

I bought this for cement Crafting projects and it really does help with the setting time. Objects seem to demould better to. I'm pleased with thus product and will continue to use.

does what it states and makes the cement/ mortar easier to use. Would recommend for any outside work
