Dulux Aquatech Waterproof Crack & Gap Filler – High-Strength, Non-Shrink Sealant for Interior/Exterior Wall, Roof, Terrace, Home, Kitchen Sink, Tile gap, Repair Concrete Leaks Up to 20MM (White 1KG)

Do it yourself, good adhesive quality product.

Probably the best crack filler available. I use it for exterior repair.

I was looking for some solution for a part of wall which had become damp. I thought this would help me but the quality of the product was not up to the mark. It was filled with some mixture with a grainy texture and very less quantity. Application became a nightmare. So avoid.

Consistency waz not suitable for filling cracks. Setting was slow
