Rated 5 out of 5 by Practical and effective Great solution to leaky joints in bricks and mortar. Goes on well, works well externally and internally. Worth taking the time to do the job properly for best results. 3 Feb 2016
Rated 5 out of 5 by Excellent product Excellent product, Read instructions carefully especially preparation and follow recommendations. 12 Nov 2015
Rated 3 out of 5 by Out of date This coating deteriorates with age before it is applied. It needs to be used within six months of manufacture. When I got home and took the tub out of its outer cardboard box I found that it was well past the six months. So I had to drive back and return it. And all the other tubs in stock at my local Screwfix were also out of date. It looks as if Screwfix does not have a good stock control system for handling perishable products. 18 Sep 2015
Rated 1 out of 5 by CHECK THE DATE!!! Had to return product immediately after buying, this product MUST be used within 6 months of date of manufacture (written big on front of container) but only stock available was more than 12 months old. Screwfix are great but really should check stock dates............ 24 Jul 2015

I have a cement rendered internal wall of my garage and water seeps through it when it rains, the wall does not seem to dry out at this time of year, Can I apply this coating when the water is running through the cement render or will I have to wait until the wall dries out?

Answers

Answer: 
If the water is literally 'running' through an internal wall there may be a structural problem, leaking pipe, roof or gutter that needs investigation & attention first. No internal wall should have water running through it and whilst this product will waterproof, the problem may be transferred somewhere else in the structure.
However once this issue has been investigated and if a waterproof coating still required Sika Waterproof Coating should be applied to damp but not wet substrates.
The full preparation guidance is as follows:
All surfaces must be clean and sound. Use Sika® Concrete Repair Mortar to repair any existing cracks and fractures before applying Sika® Waterproof Coating.
Remove all loose material, dust and any previous coatings (plaster, paint, bitumen, oils etc).
Wash down with a water jet to clean and dampen surface. Always apply to a damp, but not wet substrate.
