We all know that we can’t stop working just because the colder weather is only around the corner, but we do have some top tips to keep you working well, this winter:
1) Check the Weather Forecast
We recommend between the months of mid-November to early April that it is worthwhile to plan and check the expected weather conditions in advance of starting external render application jobs.
2) Be Aware of Temperature
K Rend cementitious products have a working temperature range of 5°C to 35°C. It is very important that render products are not applied onto frozen surfaces and that surfaces are always protected from rain or frost for a minimum of 48 hours after application, whilst the render is curing. Drying times may be prolonged in colder conditions, as well as if there is rainfall during application this may cause limebloom, particularly on deeper colours of render.
3) Keep Substrates Dry
This is a key thing to remember as a wet substrate can prove problematic with adhesion and bonding due to a lack of suction, weakness and reduced bond for the render. Even surfaces which have become saturated and are only dry on the surface can lead to potential problems such as limebloom.
Check out some of our K Rend Products we recommend for Winter Working:
Mineral TC is a cement based, polymer modified render, requiring only the addition of water and 10 minutes mixing time. Benefits include faster drying times at lower temperatures and high humidity.
Accelerator is a liquid additive used to reduce the waiting time before scraping K Rend scraped texture renders. It accelerates the curing time of K Rend scraped texture renders meaning that the render may be scraped earlier, enabling a faster completion of the job.
