About this product
A rapid-setting mortar with a rule most repair mortars do not have: never wet cure it. The sheet asks for protection from rapid moisture loss during the first three hours with a curing compound or polyethylene.
Using this specific product
Sika SikaSet-45 is listed here as the Rapid-setting repair mortar (CA) version for concrete repair and anchoring. For repairing concrete or masonry, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Rapid-setting repair mortar (CA); related versions can use different timing.
- For concrete repair and anchoring, pay particular attention to substrate moisture, depth, temperature and protection from traffic.
- At 20°C (68°F). ASTM C266, modified. Final set is 15 to 25 minutes. At 23°C (73°F).
How to check readiness
Check the slowest, coolest section before loading or coating. The sheet says to mix, place and finish within 10 minutes of adding the powder to water. The sheet gives an initial set of 10 to 20 minutes. Try a protected edge first and avoid turning, dragging or concentrated loads.
Avoid this mistake
Early strength, coating readiness and full cure are separate decisions.
