Product Information

Once the wall is correctly cleaned down you will need to remove any air vents and extend them out and also any window sills if they are particularly shallow e.g. bring them out to the new surface level of the finished wall.

Lime Render: Used mostly on older, period properties, the lime allows it to breath very well and stay flexible, helping to prevent damp, especially in properties that have solid walls and no cavitiesAs in this example, the wall needing to be rendered is fairly large so the render is mixed using a cement mixer. As stated the ratio to use for your first mix is 5:2:1 – 3 sharp sand, 2 soft sand and 1 cement. While the process sounds pretty simple on paper, I must warn that a grinder and a sander are two very powerful tools that might be overwhelming if you are a beginner. While grinding, add water as mentioned above to lubricate the grinding process. Once it is hard enough to push a rendering float onto the surface without render bulging out around the float, you can begin to float the surface up. Although correctly applied render is fairly waterproof in its own right, it can be a little dull to look at so many choose to increase the visual appeal of render plus make it more water resistant by painting it.

Weather Protection. It serves as a protective barrier against elements like rain, wind, and sun, safeguarding the underlying wall and interior from damage.For the second render mix this again will be a 5:2:1 mix but this time you’ll need to use more soft sand than sharp sand so the mix will be 3 soft sand, 2 sharp sand and cement. Mixing the Render Sand and cement render is produced by meticulously combining sand, cement, and water in specific ratios tailored to the wall type and intended usage. Precise measurement and thorough mixing are essential for consistency.
