On the wall, the application is simple, but how to apply coating on the roof? Let’s discover.
Apply the coating on the roof
You can cover the roof with coating. This is a process that helps us to leave the roofs as new. The application of the coating is simple if you take into account that with the help of the best roof coating, you can cover any wall. You must choose UV resistant coating. When it comes to the roof it seems that the thing is complicated. We are going to explain now how to apply coating on the roof, step by step and in a way that doesn’t cost you too much work.
Steps to apply coating on the roof:
The only thing you need to be able to apply coating on the roof is the coating, obviously, as well as a spatula and a trowel with which to extend the product well. The steps to follow are those.
First of all you should observe the roof and check that it does not have any cracks or holes since they will need more coating so that they do not appear again once you have finished our work.
In addition, it will be good that the roof is clean of dust and also see if there is any moisture that you have to repair before starting to apply the coating.
Once you have the wall ready, you must do the coating, mixing the coating powder with water (according to the amounts indicated on the package). Stir well and once you have created the coating paste, you proceed to the application on the roof.
You will start by taking a small amount with the spatula and this is placed on the base of the trowel. Now bring the spade to the roof and pass it gently.
Do not put a lot of coating as it may fall on you while you are placing it and do not stop extending the coating well so that there are no lumps.
To access the roof, you will need a ladder, so you will need to do the coating in a container that you can then place or support on the last step of the ladder so that it does not cost you much to take the coating.
You must give soft coating passes on the roof and once it is all covered check that it has been very smooth. If you think you need a second pass, proceed with it.
Once the preparations are finished, you place a uniform layer of acrylic sealant with a brush. Its function is to adhere the paint to the surface. It is important to let it dry for at least 12 hours and not let more than 24 hours pass before moving on to the next step.
To finish, you pass the product with the roller without putting too much pressure. The idea is to obtain a similar result and let dry. Then, apply a second layer and make sure to cover any cracks, drains or any installation with cables. Finally, reinforce the contours with one more layer.
Avoid leaks in a flat roof
Regardless of the type of liquid product applied to the roof, to obtain a long-lasting leak-proof roof, the applicator must obtain a substrate surface free of adhesion inhibitors, carefully treat the details and correctly apply the liquid waterproofing membrane. On roofs where leaks appear, these occur mainly in details that have not been properly treated; these details are ventilation pipes, exhausts, skylights, air handling units placed on the roof, parapet walls and flashings of the eaves. Details are the most sensitive places where water can infiltrate and eventually create leaks.
Materials for coating roof increase the resistance and prevent problems of leaks and moisture. Before coating, let the roof dry. Otherwise, the coating will not last long. All roof coating does not contain harmful petroleum distillates, hard abrasives or ingredients that can cause irreparable citrus damage.
