For any serious business you need to prepare well. Before proceeding with the coating, it is necessary to carry out preliminary work to prepare the surface of the roof. First of all, you need to get rid of irregularities if they are available.
To do this, it will be necessary to make a concrete screed that will remove all the flaws of the surface.
When pouring the screed, be sure to take into account the factor that it should have a slope, about 1 cm per meter, so that rainwater has the opportunity to drain. How it’s done? We take the level, and, using the ordinary thread, we make marks, along which the cement screed will be poured.
In the event that there is an old coating on the roof, which was laid using the resin, it must be removed to the very base, that is, to the screed or plates.
After all of the above, you need to take a broom and remove all the garbage and dust. This is done so that it could be safely applied to the surface of mastic. The main rule is the mastic to go to absolutely dry concrete.
It is necessary to apply mastic with a roller or brush, depending on the surface area.
You can start laying roofing material only after the mastic is completely dry. In no case do not start work with a threat of rainy weather. Roofing material can only be laid on a dry surface. Therefore, it is best to put it into a warm dry, you can slightly windy, weather.
The process of work
Everyone who at least once engaged in construction is known how to cover the roof with roof roofing. However, we want to remind you that it is usually placed in at least two layers. The first is a gorgeous type of roofing material, it is absolutely even, adhesive on both sides, and the second, with the upper layer containing the crashes consisting of the smallest stone crumb.
If the roof is flat, or it is planned to be actively operated, then the number of roofing roofing roofing material is recommended to increase to 4-5!
We start work from the lower roof point. This is done so that the upper sheets would overlap with the lower sheets of roofing material, in order to avoid watering between them. The last layer of roofing material lies with an offset of half a list, avoiding the coincidence of the seams.
Sheets are best cut in advance to facilitate further work.
The layers of roofing material is better to cut in advance and let it lay down for several days. The first prepared sheet must be put on a place planned on the roof and temporarily twisted in a weak roll. Carefully watch that the sheet does not shift, and when repeatedly promoted, again lay down where it was planned.
After that, heat the roofing material and mastic by the burner. To facilitate the process, on the roll, from the side where heating is carried out, there is an oilcloth – an indicator of heating. When she whitts and burns, you can start gluing roofing material.
The heated area must be attached to mastic with force and pass on top with a special roller. In the presence of irregularities, instead of the rink, nailed roofing ground with your hands. We put on gloves, take a rag and trample with your palms, so that the roofing material sticks well over the entire surface.
Carefully make sure that there is no importance. Before covering the roof, the second layer must wait to cool the first layer.
