Applying render provides an attractive and clean-looking exterior for commercial and residential properties. With a vast range of colours and finishes, there is a lot of choice when it comes to choosing a render system.
Before You Start
It goes without saying but you should ensure unopened packs of render are stored appropriately in a dry place to prevent damp from caking the render. Unprepared render also has a shelf-life, so make sure to check this before using it on a project.
Be confident that you know exactly what the render will look like when dry. If necessary, create a test panel.
First, make sure you have all your tools ready and the render has been made up according to the instructions.
Most renders can be applied by hand or with a spray machine – make sure to check which type of application is suited to your render.
Apply the base coat to the required thickness and allow it to cure before applying any further coats.
Render needs time to cure, which is best achieved in warm, moist conditions. The initial curing process should be closely monitored over the first 2-3 day - The render should be kept from drying out, shielded from direct sunlight and protected against frost. Make sure to check the instructions on your render for any additional precautions or advice, specific to your render.
Render needs time to cure effectively over a period of 3 weeks to achieve its final colour, and the render should be kept protected from inclement weather such as rain and high winds during the 24-48 hours immediately after application.
Extra care should be taken when applying render in cold conditions. It is not recommended to mix or use render if the temperature is below 5oC as cold temperatures slow the curing of the render and freezing temperatures halt the process entirely.
