APPLICATION INSTRUCTIONS
Alka 310 is supplied in ready-to-use pails.
Preparation:
Surface must be clean, sound, smooth and dust-free as well as oil-free.
A compatible primer. Epoxy should be applied to ensure membrane adhesion to the substrate and to prevent outgassing from the concrete.
In the case of high porosity, wet concrete (humidity >5%) or in any doubt, it is recommended to use a hydro-epoxy primer. Compatibility of the primer with the membrane must be checked prior to application.
Alka 310 can be applied with a brush or a roller to the desired thickness.
2 coats of 0.8 L/m2 (1.04 kg/m2) are required to achieve a dry film thickness (DFT) of 1.2 mm. For UV resistance, coating thickness must abide by the numbers given on this Technical Datasheet. A thinner coating will result in premature degradation. Application temperature of Alka 310 is >5°C to 35°C.
Alka 310 can be subject to light foot traffic after 24 hours.
Vehicle traffic is not permitted on Alka 310 without the application of a top coat. Where extended UV resistance is required, it is recommended that Alka 310 be coated with an Alka topcoat system such as Alka 210 Polyaspartic. Check with your ALKA Representative for compatibility before application.
Recoating instructions:
In normal conditions, Alka 310 can be recoated with another layer of Alka 310 after one night and within 2 days. In case of rain or if the recoating interval was exceeded, come back to the substrate by grinding.
Contact your Alka Coatings representative with any questions.
1-2 layers of glass fibre cloth or other carcass materials can be added in the middle of the coating. Generally, 1.5-2.0 kg/m² for a 1 mm thick rubber-like membrane to form.
Clean-up
Reusable tools should be cleaned carefully with Xylene or MEK before curing.
