As with other tasks, the most essential part in rendering is preparation. You need to make sure that the surface you wish to render will be free from dust and flaky or loose residue. If necessary, you have to prime or damp down the surface using a bonding solution like a cement bonding agent. When you wall is ready, you can now select a high quality polymer render.
When you need to apply cement to your outside walls, you need to apply rendering. This process involves mixing lime, cement and sand. You then apply the mixture to your wall to come up with a finished appearance. Depending on the application and sand you use, your wall can be textured or made smooth. The following are the steps to mix rendering.
Prepare the Ingredients
A lot of people utilize around six parts sand, one-part lime and one-part cement for making rendering. You have the option to either use soft or hard sand that will provide you a grittier feel for your mix. You can also find regular cement and lime at a hardware store to help in reducing moisture from seeping into your rendering mixture.
Measure Ingredients
The measurement will ensure accuracy. To come up with a measurement that is consistent, make use of a container like a small bucket rather than a shovel. Just make sure that you level each time.
Add the Ingredients
You can place the ingredients in a huge container like a wheel-borrow. Put a small amount of water to your valley with the use of a towel or shovel so that the rendering mix can be pulled toward the center. Turn the mix and add some water until you reach solid consistency on the trowel. The mixture is now ready for wall application. Thickness varies up to 12mm which will depend on how bad your substrate is. When finishing your rendering, dampen a sponge and utilize small circular movements as you take out any voids or high points. As you are able to cure this, your newly rendered surface is ready to accept decorating coating.
It is just important to wear protective clothing when doing the process especially when you will be working lime. When making rendering, try to do it in small amounts so that you can obtain the consistency and feel that you want. Mix a container or wheel-borrow of rendering at once and then apply it to your wall in a prompt way to make sure it doesn't dry up.
