Minimum application temperature: 5°C
Vetocure XT426 should be spray applied to the surface of fresh concrete. The application should begin immediately after the concrete is free from surface water. Do not apply if bleed water is forming or present on the concrete surface.
The spray nozzle should be held approximately 450 mm and inclined at 35° to 45° from the concrete surface and passed back and forth to ensure complete coverage. The fugitive white color during application provides a guide to the area covered. Maintain pump pressure to give an even, fine spray.
After spraying, no further application of water or other material is necessary to ensure continued curing. The concrete surface should not be disturbed until it has sufficient strength to bear surface loads. Prevent the walk on the applied film until it is fully dry, and ensure that the film is not broken.
Vetocure XT426 may also be applied to the surface of newly hardened concrete immediately after demolding. In such cases, the concrete surface must be damp and not dry. Dry surfaces may prevent correct film formation and cause absorption of the Vetocure XT426, which may lead to staining and difficulty in later removal.
