FLEXI 12 FREEZES CRACK
Once this has happened, it’s only a matter of time before the crack starts to grow due to the constant expansion and contraction of the water during the freezing and thawing process. If your render has cracks within it, then water will be drawn into the crack to settle within the material.
FLEXI 12 FREEZES CRACKED
Freezing temperatures can have a very negative effect on old, cracked renders – particularly sand and cement renders as these are the most prone to large cracks. Most often, damage to render occurs years down the line. It significantly reduces the risks of failed render when applied in the winter months. Ideal for mixing in with our ready-mix renders, the render accelerator speeds up drying times so that the render isn’t left wet and exposed to the elements for too long after application.
The Winter Adhesive can be applied at temperatures even down to zero degrees, so it allows for a level of flexibility in terms of application temperature and year-round work. The ideal solution for when there is no escaping the weather. Products that offer a solution to application in cold temperatures:įreezing temperatures are a no-go for applying render, but there are a couple of solutions for the winter months when the temperatures are consistently low. It can also make its way into the brickwork, where it will freeze and thaw repeatedly. This means that when applied and then left to dry overnight in freezing temperatures, the water within the render will freeze and expand, causing cracks to form. The likely cause of failed render application is that the temperatures are so low, the water within the formula will not properly evaporate from the render. Different manufacturers give different instructions so always check the bag, but the general rule of thumb is that if you are applying your render in especially wet, rainy and freezing conditions then the render is likely to fail. The application temperatures of most renders generally falls between +5☌ and +25☌, although this can depend on the type of render and the brand that you are using. Freezing Temperatures and Render Application This week, we’re going to talk a bit about the effect of freezing temperatures on your EWI and render system. As we know, however, freezing and thawing cycles of water are incredibly destructive for any material. Render is designed to act as a protective barrier, ensuring that harsh temperatures and climates have a minimal effect on the structure of your property.
