Runoff Layers

Soft roll krovlyaustraivaetsya depending on the slope of ramps in several layers, with a slope of more than 15% – in 2 layers, with a slope of 5-15% – to 3 layers, with 0-5% slope – in 4 layers. Preparatory processes for the device of roll roofing materials is the preparation and cooking primers, mastics and reel material to the label. Beginning with a vapor barrier under the training grounds, including the device under crater supports internal drainage. Then the roof served paste. If a vapor barrier is used vellum, paste it on mastic. To label roll material to the substrate using hot and cold mastic. Cold bitumen mastic before installation on the base melted to a temperature of 150-160 C. For the preparation of hot mastic asphalt is melted to a temperature of 220 C, then injected powdered mineral fillers such as talc, diatomite, tripoli.

Before laying on the ground should be prepared roofing material. For this it must be smoothed out with simultaneous cleaning the surface of powders and conditioned for 24 hours. Materials that do not have the coating layer, winds on the other side. If the roofing material to be laid in cold mastic, clear it from spreading is not necessary, since it is absorbed by the cement and becomes her carrier. Sticker roll of cloth adhesive cloth roll materialov.Dlya Related material used mastic. The layers of roll roofing materials, prepared on the basis of bitumen, bitumen mastic paste and only – Degteva compositions.

When the label panels should be considered value of roof pitch, the direction of water flow, the direction of prevailing winds and air temperature. Paintings on the roofs with slopes up to 15% paste in the direction of lower to higher places with the location of their perpendicular Runoff water. On roofs with a slope of more than 15% of fabric bonded to high places to low water flow in the direction to roll the carpet does not slip.
