With the Wintery weather upon us and temperatures dropping it’s important that you are aware of how this weather can affect the performance of some building and DIY products. So we have put together some handy tips for using our products this time of year:
Liquid Roofing Systems
Always bear in mind the temperature parameters of our PROGRP, Hydrosil and Flexiglass (always consult the application guides before use) and ensure that no jobs are started if rain or a sudden temperature drop is imminent. By keeping the products in a warm environment such as by a radiator or in the footwell of a van (with the heater on) you can improve the curing times.
In general all coatings should be applied above 5°C.
In colder and wetter climates Cromapol tends to thicken up and becomes less practical to use. In colder climates the coverage rates will be affected as well. It is always advisable that the application surface should be clean and dry and the deck temp should be above 5°C. It is also recommended that Cromapol should be kept at room temperature prior to application. Drying times may also double in the winter.
Once Cromapol is applied to the surface it is waterproof immediately and frost resistant.
In cold weather, i.e. below 5°C, the adhesion on the flashing will be reduced so should not be applied. We would advise warming the surfaces with a gas torch or blow lamp (where safe to do so), or storing the flashing in a warmer location prior to use.
Professional Decorators Caulk
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.
With all of our aerosol products we would recommend that the tins be warmed up – ideally in a bucket of warm water before use. Always make sure you shake the can thoroughly before use.
Solvent based solutions
In colder and wetter climates, the product tends to thicken up and become less practical to use. In colder climates the coverage rates will be affected as well, it is therefore advisable that the application surface should be clean and dry and the deck temp should be above 5°C. It is also recommended that the solution should be kept at room temperature prior to application. Drying times may also double in the winter.
Water based Bitumen solutions
Wood adhesives should not be used below 10°C as the temperature will affect the curing of the glue. A good general rule is that if it turns white then it has been too cold to apply it. Equally you should not allow the glue to freeze, if stored in a workshop or van, as the glue will be significantly weaker even after it defrosts. It is important to ensure that the temperature is also maintained throughout the drying time to ensure an effective bond.
