A. Generally, caulk should be applied in warmer weather, ideally above 5°C.
If you do need to apply it try putting your tube in a bucket of warm water before use to bring it up to the right temperature. Or if it is stored in a garage or van, bring it inside the house the night before use so it can warm up. If caulk is applied outside of the temperature range, even high performing caulk like our AlphaChem Caulk, won’t flow as well out of the tube, won’t sit right in the joint and won’t tool as well.
