Questions
Question about the product
tom bulgin on 2022-02-15 23:32:25 | Question:
Can this be used in screed for underfloor heating? What is the curing time in well ventilated 5-10 degree temps? |
Answer from Rawlins’ Technical Team:
This product can be used to aid the rapid hardening of cement based mortar, concrete, screeding and render. We would recommend consulting the technical data sheet for the screed this is to be used with regarding compatibility and application. At 20°C the addition of 5ltr of Sika Accelerator to 50kg will produce an approximate setting time of 2 hours. | |
