Sikaflex Construction+, Grey, Sealant for concrete and masonry facades, Ready to use, Movement and connection joints, 600ml

Best waterproof for cracks.

I used 4-5 water proofing compounds so far as my roof to roof concrete joint have gap between them. The adhesion strength and flexibility of Sika sealent is excellent on masonry work. No water seeped in last 15 days after many rainfalls. The only issue is it packaging, it's sealant cartridge can not be used with normal clunking gun so application is messy and cumbersome. We should get this sealent in normal clunking cartridge with nozzle.

Good product effect ive .

Great sealant.Slightly messy to work with, even with a putty-blade.It would be a good idea to consider plopping this into a sealant gun.

I have a seepage in roof for a long time and tried all sort of things to seal it permanently, however nothing stayed for long. Then I came across this sealant and tried this. I widened the crack cleaned it and applied GP silicon instead of foam as filler. (Keep the corners clean for this sealant.) Thereafter applied this sealant without a gun as normal gun is short for sausage. It is super sticky and I forgot to wear gloves and even silicon spatula doesn't work. Used steel putty patti to apply it and water sprayer for dressing. Even after using every detergent, thinner, kerosene, alcohol it stayed on hands and could only be cleaned to some extent by rubbing cotton cloth repeatedly, traces of it stayed for few days so wear gloves. End result - after three months of usage and facing winter to summer and rain it stayed firm, let's s see how it comes after rainy season. Highly recommended if you are fed up of roof seepage.

Was facing leakage from wall cracks and window joints.... Treated the cracks using Sikaflex PU sealant and could paint over it also. Till now no leakage observed despite pre monsoon showers. Excellent product will surely recommend to use this product

Very good for filling joints and cracks

Good one
