Rated 3 out of 5 by from Out of date This coating deteriorates with age before it is applied.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 And all the other tubs in stock at my local Screwfix were also out of date.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

is it ok to cover with underlay during the curing time?

Will the dried sika coating still cure properly if it is covered with underlay boards and laminate as a temporary surface to walk on during the 6 month curing time? thank you
Asked by: sawood
This should be fine and the Sika Waterproof Coating should cure properly.

must i wait 6 months before tiling over?

Is the cure time really 6 months before tiling adhesive and ceramic tiles are placed over this product? (solid floor, concrete with absent membrane currently, and damp is affecting wood joinery that is in contact with the floor) thank you
Asked by: sawood
Yes, 6 month must be left before final decorative finishes are applied (e.g. tiles).

What coverage does a 5kg tub have?

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.

Asked by: help02
You need to allow 6 months for the product to fully cure before over-painting.
