VERY FAST curing crack / joint filler for all external substrates. Very tough and can be used by heavy traffic in just 30 minutes!.
For easier application use the External Crackfiller Drawbox
External Crackfiller is a cold, liquid applied, fast curing system based on advanced resin technology. External Crackfiller is fully waterproof and has been professionally developed to both fill and seal cracks and joints in virtually any substrate – particularly asphalt and concrete. With superb adhesion, External Crackfiller is highly flexible, will allow for expansion and contraction and is suitable for all cracks and joints from 3mm to 50mm wide.
It is available in two grades – Standard and LT (for a faster curing time at Low Temperatures).
Typical Uses:
External Crackfiller is designed for the filling of cracks and expansion joints in asphalt and concrete substrates.
Suitable Substrates:
External Crackfiller is suitable for concrete, asphalt and tarmac surfaces.
Colour:
External Crackfiller is dark grey in colour.
Packaging:
External Crackfiller is supplied as a 12.5 or 25kg unit. It is a twin pack product supplied in pre-measured quantities of Part A and Part B plus aggregate overscatter of 1.5kg for the 12.5kg unit and 3kg for the 25kg unit.
Pot life: 5 mins @ 25°C. Curing times will be extended by lower temperatures (see TDS for timings)
Application temperature: 0°C – 25°C
Number of parts supplied: 2
Priming required: No

Surface Preparation
THOROUGH SUBSTRATE PREPARATION IS ESSENTIAL.
The surface to be treated must be clean and dry. Use a stiff brush or compressed air to clear the crack of all dirt, standing water and loose material.
Mixing
Ensure the area to be treated is fully prepared before starting the mixing operation. Stir the resin thoroughly immediately prior to use. Whilst continuing to stir add the powder catalyst and mix thoroughly for a further 30 seconds, scraping around the sides to ensure the catalyst is fully dispersed. This initiates the working life during which time the crackfiller must be used. The pot life is only 5 – 15 minutes so without stopping, move quickly on to applying the material.
Application
Pour the mixed material into the draw box and pull it over the surface to fill the crack or joint leaving an even band of material. Keep the draw box level and flat on the ground at all times. Towards the end of the working life polymerisation starts, the viscosity increases (i.e. it becomes stiffer, the temperature rises and the material will start to gel). Do not try to place or work the material further. Discard the remaining material and clean tools quickly.
