Why do houses need render cleaning? –Tips and Techniques for the process
Render finish can be seen on many houses in the UK. It is a layer applied on the walls for their protection against dust, rain, humidity and moisture and is applied on the external walls only. The Render mixture has the ingredients of cement, water, sand etc. In fixed proportions. The percentage is definite because it gives the mixture its required viscosity and strength. However, some other material such as silicon can also be added to mould the properties of the mixture. After applying a coat, it is left to dry and then other coats are applied to even out the underlying structure of the walls. Render cleaning is then done to make the layer last for years.Â
Why is it necessary to go for render cleaning?Â
Renders are good to make a house attractive to buyers and renters. A fresh and clean house always stays on top of realtors’ selling list. But render, like bare walls, is also vulnerable to dirt and fungus which accumulates with years. Usually, those who are not entirely known to render think that their house needs a new paint, Teflon or renovation. Instead, they can get a fresh look like before just with proper professional cleaning, which is also a cost-saving option as compared to repainting. A clean-render house:
Has a new appearance
Kerb of the house look more appealing and better
Saves money which would have been spent on repaintingÂ
Has the render stayed undamaged for years.Â
If the render is cleaned and maintained timely and properly, it can last up to 15 years and this can only happen if the cleaning is done time and again. Other than the classic white, there are other colours of render which enhance the appeal of the house and there’s a technique to clean them. However, there are some things which professional cleaners take care of such as:
They check out if there’s any plant growth or vegetation:
In areas where the weather is humid and moist and the houses are mostly exposed to rain, algae start to grow on the corners of the rendered wall. Before applying any pressure wash, they look out for such growth and clean it with a soft-thistle brush, ivy, a hard sponge etc. They also make sure that greenery which is not yet visible but has a chance of appearing later on is removed properly.Â
They have the right protection:
They also apply coating on renders while cleaning, if the customer asks for it.
They know how to wash it
If there are any stains or spills such as that of oil or any other, they use a mixture of water and detergent and give a slight pressure wash to make the render get rid of such stains. They have machines which can change the pressure of the water according to the types of cladding cleaning needed. They also have tools to adjust on the mouth of the jet to split the direction of the water so the render cannot be damaged in the render cleaning process.
