Rated 3 out of 5 by from Out of date This coating deteriorates with age before it is applied.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 And all the other tubs in stock at my local Screwfix were also out of date.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

Rated 1 out of 5 by from 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............

Can this be applied to a damp masonry surface?

Can this be applied to damp stone steps in a cellar?
Asked by: James85
You should be able to apply this product to your steps but you would also have to use a sand / cement screed over the top when the Waterproof Coating is dry. Final decoration after this (paint etc.) would be after six months.

Use with adhesive

Can I use a flexible wood floor adhesive (saline based) on top of this? The adhesive instructions are unclear.
Asked by: Biscuits18
Not sure what that adhesive is so unfortunately we are unclear as to its compatibility or suitability. Wood flooring is very susceptible to moisture which can damage it and cause cupping, so it's worth looking into this carefully and possibly using a system of products together to get the best results is; a damp proof membrane and adhesive.

Can it be tiled over?

I've had Lino in my kitchen that has got damp and ruined. I suspect it may be coming up through the concrete floor. Will this product provide a waterproof barrier over concrete floors and the can I tile over the top? Thanks in advance.
Asked by: Jay123hdv
It is a durable cement based coating and can be applied over concrete floors to prevent damp and water penetration. When fully cured floor coverings can be applied including ceramic tiles.
