Tips for Performing Wall Rendering On The Exterior Of Your Home

You can render the exterior of your home for a number of reasons. Some of these are that it uplifts the look of your home so it looks newer and better, it is a means of protecting the exterior walls from damage that comes from weather and other environmental conditions and it is also a way of upgrading your house without spending too much money. It is done by plastering cement and sand and the finishing can be done in different textures such as smooth or rough depending on your preference.

To render your exterior walls, you must first get the supplies that you will need. These include tools such as trowels, steel brush, mixer and materials such as cement, plenty of water, sand and others. Once you have done that, you should prepare the walls so that the surface is as smooth as possible. This will make it much easier for the render to go on and the finishing will look more professional. If you had rendered your walls before, remove any old render materials using a steel brush. If the wall has any old paint, brittle mortar in the joints if it is a block or brick wall or any other old loose material, use the steel brush to remove all these.

Once the walls are smooth, you should then mix your render. The instructions will paper on the bags of cement and other materials that you have. It is important that you follow the instructions provided when mixing the render so that the consistency is correct. This is important because if you do not get it right, the render on the walls will chip and fall off easily shortly after it has dried. The kind of wall that you are rendering will determine the number of coats of render that you will put and the consistency of render that you will use. Older walls need a stiffer coat of render and may require more coats as compared to newer walls.

The first coat will be thickest coat; subsequent coats of render should be thinner. If the subsequent coats are thicker, the walls may crack because of the weight of the upper coats. When mixing your render, do not mix large amounts to avoid waste. This is because if you are not able to finish the batch it will dry and cannot be used. If you would like to use pigmented render, add the pigment when mixing the render.

When rendering, start from the top and work your way down. Use long and smooth strokes with a trowel to apply the render. This will ensure that you are applying it as evenly as possible. If you are applying two or more coats it is best to apply the second coat before the first one has dried completely. If the sun is too hot, wet the walls so that they do not dry too fast which may lead to the formation of cracks. Once the render is dry, use a plasterers sponge which is damp and take out any voids or high points using small circular movements.
