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Rated 3 out of 5 by Out of date This coating deteriorates with age before it is applied.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 And all the other tubs in stock at my local Screwfix were also out of date.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

Answer: 
We don't recommend it for this purpose as there are specific specialist products available for tanking wetrooms in bathrooms. They are proven and tested for the application plus are compatible with the other materials you will use during the project so its bet to use those as a system.

Sika® Waterproof Coating is a durable cement based coating used to prevent damp and water penetration in walls and floors, both above and below ground level. It is ideal for use in basements and cellars and may also be used as an external coating for concrete, brick, block and bonded renders. It offers excellent adhesion and can be painted after hardening.

I have emptied the gully (where the DPM is) of gravel and discovered 2 pipes so I am assuming that this is a French drain?

Answer: 
Yes it can be applied to an external wall to prevent damp penetration but you do need to be sure that its not 'rising' damp from below the DPM as it will not stop that.

Answer: 
You really need to establish where the water is coming from as Sika Waterproof Coating will prevent damp entering through the wall above ground level but it will not help if the damp is 'rising' as a result of an inadequate damp proof membrane. It is a rigid coating and is not suitable for use over areas prone to movement where an elastic sealant like Sikaflex EBT can be used.
