UltraCrack is a methyl-methacrylate (MMA) cold plastic product that is designed for crack infill and overbanding. As with all MMA products it is very fast-curing, which makes it ideal to live traffic situations where road closure time needs to be kept to a minimum. It is very durable, enabling permanent repairs which will outlast the surface itself, extending the life of surfaces by resisting the inflow of water and minimising damage caused by freeze/thaw.The product is a cold-lay product, requiring no hot works or specialised equipment; along with its simple application method, this puts the product within the reach of any competent install team. This allows the best use of human resources and enables a rapid response to any reactive works, without the cost or lead-in times associated with specialist subcontractors.It is suitable for any asphalt surface, including roads and highways, pavements, airfields, station platforms.
Features and Benefits:
- Fast curing – allows traffic within minutes for minimum disruption on site
- Durable – resistant to wear
- Strong – adheres well to any surface
- Skid Resistant – natural skid resistance that can be optionally improved
- Easy - simple application with little training required
- Safe – applied with no hot works or big equipment
- Cost effective – reduces defect costs and obviates specialist call out charges
- Flexible – follows any movement of road surface
Surface preparation: The application surface should be dry, sound and clean, free from grease, oil, rust, scale, dirt, or any other soiling that might affect adhesion or performance.
Mixing ratio: As supplied.
Mixing instructions: First stir the base resin, then thoroughly mix the bag of catalyst powder into the Resin with a mechanical mixer, ensuring the powder has fully mixed throughout, and stir for 30 seconds.
Please note that once mixed, the product will start to cure rapidly! In warmer conditions, it is acceptable to reduce the amount of catalyst powder added, by up to 25%. This will slow the curing process.
Thinning: Do not thin.
Lay the UltraCrack using a hand-mould - we recommend a funnel-top version for ease of use. Pour the UltraCrack into the mould using a jug and extrude the product along the line of the joint of crack.
For higher level of skid resistance value (SRV), overscatter the product immediately with 1-2mm grey bauxite supplied with the kit.
Do not apply when the air or surface temperature is below 5°C or less than 3°C above dew point, or if this is likely to occur during the curing period.
Do not apply when there is rain, mist, fog, or snow imminent; when humidity is high or the surface is wet with condensation or likely to be during the drying period.
