Concrex strength, will withstand very heavy traffic after curing overnight

Watco Concrex Fine Filler is economical to use as you mix only as much as you need. It is virtually solvent free and will not shrink as it cures. No primer is necessary and it can be used for repairs with a very fine edge (feather edging). Watco Concrex Fine Filler is extremely strong and its adhesive strength to clean concrete is greater than the strength of concrete itself. For repairs deeper than 5mm we recommend you use Watco Concrex Original. Coverage approx. 1 litre per 1.5kg twin pack.

Preparation

Surfaces should be clean and free from dust, oil, grease or other contaminants. Surfaces should be sound and not friable. Any exposed steel reinforcement should be cleaned to bright metal. Some surface dampness can be tolerated, but surfaces should not be wet.


Mixing
Wearing the gloves provided in the pack and using the spatulas provided, take equal sized portions of the resin (off white), and curing agent (black), and mix them together thoroughly on a suitable mixing board until they are a uniform grey colour. The ideal mixing ratio is 1:1 by weight or volume – you should try to estimate equal quantities accurately, but there is no need to weigh or measure them. Do not mix at one time more than can be applied in 15 – 20 minutes.

Application
Using the plastic scraper provided, press the mixed components into the repair and smooth off the surface. Any spillages should be scraped away or wiped off with a dry cloth, and can be cleaned with white spirit. The finished repair may be filed, sawn or drilled – take care not to inhale the dust from these operations. Finished, hardened repairs may be over painted after 12 hours/overnight curing.
