## Description

From the manufacturer

Review: Excellent stuff! - This stuff was excellent. Pretty easy to use and seemed to adhere well. Only time will tell so I’ll submit another review update in about 6 months. It was a good colour match for grey mortar and seems to have dried pretty quickly. The nozzle was wide enough for the mortar and all in all it looks decent for a novice. Pretty cheap for this sort of repair. Make sure you soak the tube in warm water before using as this really helps with easing the application. All in all it’s great!
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 - Ideal for small pointing work and removes the need to mix sand and cement.
- NO PRIMER REQUIRED - Adheres well to most surfaces without the need for a primer.
- EASY TO APPLY - Cut the cartridge seal, attach the supplied V shaped nozzle, and use a good quality applicator gun, as the material can be firm when applied directly from the cartridge.

- TEMPERATURE REQUIREMENTS - Both the product and the substrate must be above 5°C for best results.
- EASY TO CLEAN - Tools and hands can be cleaned easily with water.

This is good stuff but not cheap. Very strong repair to an area consistently hit by car and coach wheels. Holds up well compared with normal concrete
