"I bought 2 tubs from the Leeds branch. When I got home and read the instructions on the tub I noticed that they should not be used if more than 6 months from the dom. One was ok, but the other 1 month out of date.
I called SIKA and they said certainly do not use if more than 6 months old. I called Scewfix and they were unaware of this 6 months life. However, they were quick to replace the out of date tub and provide a £10 gift card by way of apology.
The product is great, but goes off quite quickly; I mixed all 5kg for the first coat and the last few brush strokes were difficult. For the second coat I mixed 2 tubs of 2.5kg each; much better."
"I am quite impressed with the ease of use of this product. Compared with bitumen-based products which are difficult to apply to uneven surfaces and have a noxious vapour in enclosed spaces, it was very easy to apply, dried quite quickly and had no smell. I used it to damp-proof a basement wall (below damp-proof course level). I can't yet vouch for the effectiveness or reliability as it has only just been applied."
"After heavy rainstorms, I was having problems with occasional severe groundwater seepage into my basement garage through a line of crumbling old bricks and mortar low down on one wall. This was seven feet below ground level so I was forced to treat the inside only. When we got some dry weather I scraped off the loose mortar and brickwork surface with a wire brush, then applied a layer of rapid dry cement. A couple of days later I was able to put on the first coat of Sika. I feel it is important to follow the Sika instructions to the letter, so I made up the mixture to their exact ( and I mean exact)specification for consistency with regard to the ratio of water and waterproofer and stirred it for a good five minutes. I was a bit wary as to how "runny" the mixture was (like slurry) but having sprayed the line of brickwork very lightly with water to just dampen it, I found I was able to brush on a coat of Sika with a large paintbrush without any of it falling off. I waited 48 hours then applied another identical coat - and since then the garage wall has been bone dry! There may be easier ways of solving the problem - I don't know - but I do know this product did the job it was supposed to so I am quite happy."
"I have now purchased a couple of these while I rennovate our house, used to waterproof an old concrete floor of 1920s house to be used as a bathroom, before tiling I found it simple to mix and easy to use."
"I used this to seal a crack between brickwork and a concrete path. It made a neat job. It looked a bit sloppy when first made up. I was worried putting on the first coat but once this had dried the second coat went on easily. Waited 24 hours between coats."
"Thought I really must review this product whilst every failing is still fresh in the mind. Over the past 4 years I have used considerable amounts of tanking cement/slurry on my renovation project, so I do know what I am talking about! Originally I bought up stocks from “Red Pencil” builder’s merchant when they discontinued the line and subsequently have used the product used by many of the professionals. As I am coming to the end of my project and this latest area was not too large I decided I would use Sika® Waterproof Coating as it was easier to stick it on the end of a Screwfix order. Having now used 2 X 5kg just for the first coat, way more than I had calculated based on my previous usage, I have gone back to Wykamol tanking,(what a difference!). The coverage of Sika® Waterproof Coating is very poor a high percentage not adhering so landing on the floor (no wanted on this occasion) I have never experienced this on brick, sandstone or concrete block in the past. Even as another reviewer mentioned wetting the wall did not help, it would hardly coat the undamaged colliery brick surface and then collected into “snots” with minimal brushing. I only hope its waterproof properties are better than its application ones. My advice is to shop around for tanking cement as price varies and as I have found so does quality."
