Review: Good price and product for small repairs. - I bought two tubes, it was easy to use although it was a little hard to squeeze out at first. Before starting you need to ensure any loose material is cleared out of the gaps to be filled otherwise the filler can fall out. The colour is a light grey which blended well with my cement which is around 30yrs old, I’m happy with the results. Like the Bruce Willis film it Dries Hard. I know!
Review: Decent enough - Good enough although it could maybe do with a little more moisture through it in order to help stick to a dry surface. Easily rectified and other than that it does its job well enough.

## Features

- Contains reaction mass of 5-chloro-2-methyl-2H-isothiazol-3-one and 2-methyl-2H-isothiazol-3-one (3:1) [C(M)IT/MIT] & 1,2-benzisothiazol-3(2H)-one [BIT]. May produce an allergic reaction.
- Safety data sheet available on request.
- READY TO USE MORTAR - Perfect for small pointing jobs, saving time on mixing sand and cement
- NO PRIMER - Will give a perfect adhesion to most surfaces without the requirement of a primer
- EASY TO APPLY: Simply cut the cartridge seal and attach the pre-cut 'V' notched nozzle. For best results, use a high-quality applicator gun, as the material can be stiff to apply directly from the cartridge

- TEMPERATURE REQUIREMENTS: Ensure both the product and the substrate are above 5°C for optimal performance.
- EASY TO CLEAN**: Clean tools and hands effortlessly with just water, making cleanup quick and convenient.
