Watco Fine Crack Filler Cold Cure
- Lightwork of heavy-duty repairs
- Structural strength solutions
Watco Fine Crack Filler Cold Cure is a liquid epoxy filler for narrow concrete floor cracks in cold conditions. It can be applied at temperatures down to 0°C, helping you carry out local floor preparation in winter, cold rooms and unheated work areas.
The pourable two-part resin fills cracks up to 3mm wide and can be levelled with a scraper before it sets. Its non-shrink formula leaves a hard grey repair that can be coated after curing. Use it to prepare the line of a fine crack before painting, with the application temperature and cure period matched to the conditions on site.
Surface Preparation
Rake out the crack, remove dust and loose material, and make sure it is dry and free of contamination. Chasing out is not normally required. Check the full length for changes in width and depth so you can estimate how much material is needed.
No primer is required. Keep the pack at 15–25°C for at least eight hours before use, as directed by Watco. Prepare the area and gather the scraper and mixing tool before combining the resin and curing agent.
Technical Data
- Pack size is 500ml, comprising resin and curing agent.
- Two-part, 100% solids epoxy resin with a grey appearance.
- Suitable for interior and exterior concrete.
- Designed for narrow cracks up to 3mm wide.
- Approximate yield is 25 linear metres at 2mm wide and 5mm deep per pack.
- Minimum application temperature is 0°C.
- The technical sheet specifies approximately 4 hours curing at 0–5°C.
- Working life is up to 20 minutes. Shelf life is 12 months unopened.
Directions for Use
Empty the curing agent into the resin tin and mix thoroughly with a flat blade or suitable slow-speed paddle. Work around the sides and bottom to incorporate material that could otherwise remain unmixed. Follow the pack instructions and safety data sheets for handling and mixing.
Pour a controlled amount along the crack and level it with a straight edge or plastic or rubber scraper. Wipe away surplus before it hardens. Allow the repair to cure before coating or overlaying it, checking the surface before the next stage of the work.
Limitations
Use this grade for surface crack filling. A moving crack can reopen, and a difference in level between the two sides needs separate attention. For wider or broken-out areas, assess the depth and consider a suitable Concrex Cold Set repair mortar.
Coverage depends on the actual dimensions of the crack. Remove food products from the working area during application and cure. Keep the manufacturer’s technical and safety sheets available when planning the repair.
Product FAQs
Can I apply it at 0°C?
Yes. Cold Cure is designed for application down to 0°C. Condition the unopened material at 15–25°C for at least eight hours before use.
How long does it take to cure in the cold?
The technical sheet gives approximately four hours at 0–5°C. Allow the repair to harden before applying a coating or overlay.
Do I need primer or sanding?
No primer is required. Level the liquid with a scraper during application to achieve the intended flush repair.
What coverage should I allow?
Approximately 25 linear metres per 500ml pack for a crack 2mm wide and 5mm deep. Wider or deeper sections consume more resin.
