Soft roofing materials - a great choice if you need to do roof repair is not only fast, but also cheap

Plan to repair the flat roof and are considering rubemast as a roofing material? I'll tell you what kind of material as it is and how it differs from the others. In addition, you will learn how to properly perform its installation with their own hands.

All you need to know about the material, before proceeding to its installation

Rubemast or as it is called rubiplast - cheap kind of soft roofing. From the usual roofing material is characterized by thickened bitumen underside, making it more flexible and more sticky when the weld.

Scope weld roll material - this is the device of soft roofs of most of the domestic high-rise buildings. For reasons of economy coating sold for arranging houses and commercial buildings.

Due to the bituminous substrate, after paving, additional waterproofing is not needed

Rubemast made of cardboard, at least from the glass fiber. Basis impregnated fusible bitumen mastic, which is applied over the outer layer of refractory bitumen impregnation. Since the coating roll, bitumen-impregnated surface is sprinkled with ground quartz, asbestos, or talc.

Application of powder material does not provide extra strength, but simply serves layer without permitting coalescence.

Benefits:

  1. Easy to install. Rubemast is fused to most previously prepared flat base;
  2. Excellent adhesion to various substrates. Material for installation sticks well to most substrates. Therefore, as a possible laying one or more layers;
  3. Low price. Rubemast - one of the cheapest roofing materials. Therefore, if you need to do roof repair inexpensive - it's your choice!

Disadvantages:

  1. Small service life. According to statistics, every 4 roll gives leakage within the first year of operation;
  2. Low resistance to mechanical stress. On the roof can not go, because as a person weighing more than 50 kg certainly strikes a reinforcing layer;
  3. Low resistance to ultraviolet radiation. On average, 1.5-2 years of sunlight on the surface of roof cladding layer formed mesh microcracks, whereby the roof loses tightness;
  4. The appearance of blisters. If the installation was originally performed on the uneven base, six months later there will be blisters that eventually will go cracks.

Available are two varieties of weldable tar paper - HSD rubemast (surfaced backing) and Rubemast RNA (surfaced roofing).

As the name implies, rubemast index RNP fit as the substrate, and the version index RNA fit topsheet. Laying the material in several layers increases resource use roofing.

Can I put rubemast one layer? A single-layer stacking - a temporary measure, which is allowed only on a perfectly smooth rigid base.

Stacking technology from "A" to "Z"

Methods soft coatings stacking the same, and therefore we consider what the guide device roofing on the roof of the garage.

illustrations Description of action
table_pic_att14914894453 Assessment of the roofing. We examine the old coating and decide whether it should be removed completely or may be left as a substrate.

If the old coating is pressed and falling off pieces of it should be removed.

Swelling on the surface of the coating - a sign that all you need to remove the overlap.

table_pic_att14914894474 Removing the old roofing material. Old roofing material as the photo poddevat shovel and torn off from the ceiling.

After overlap completely cleared, repel the hammer concrete pieces that crumble or are about to fall off.

table_pic_att14914894505 alignment bases. Before laying the roofing material, the substrate must be aligned. For this:
  • the overlapping area and sweeping the cover of any penetrating primer;
  • preparing a cement-sand mortar rate of 1 part cement to 3 parts sand;
  • solution aligned depressions so that levels differences do not exceed 2-3 mm.
table_pic_att14914894536 Priming. Before operating a roofing coating, the primer coated surface. The primer can be bought ready, and you can do it yourself.

Recipe primer:

  • The metal container, pour 76th gasoline, which is mixed into bitumen mastic in a proportion of 30 to 70.
  • The mixture is gradually heated, still stirring.

The prepared primer may be applied in bulk followed by proliferation mop. Angles and abutment are coated centrifugal brush.

table_pic_att14914894557 We put rubemast RNP. This web material on both sides of a resinous surface, which can overlay. Therefore, no matter what side you turn rubemast.

Mounting roofing underlayment start edge. If the roof has a side, put the material with an overlap of him.

The gap between the roll and the overlapping heat the burner, and while surfaced primer layer will not stick to each other.

Gradually warming up both the surface and roll out roll. Nearby are stacked end to end without overlapping.

table_pic_att14914894578 Mounting the upper layer of roofing. After the substrate is laid flooring roofing material with an upper surfaced side.

The first roll set so that the band overlaps the butt alignment of the substrate strips.

Heat the burner surface previously laid coating and simultaneously warm up the underside of the new roll. Adjacent bands overlap by 10 cm.

Laid-sealing strip homemade rammer that the coating adheres well to the substrate.

table_pic_att14914894599 Laying on the roof ledges. It's simple - cut a piece of cover, so that it was enough for stacking overlapping on the already hardened material and bend over the ledge.

Heat the burner prepared piece of material, laid it on the rim and a seal so that it is properly stuck over its entire area.

Rubemast can be laid on a wooden roof? This possibility is, but you need to make a solid crate, covered plywood or oriented strand board.

Rubemast on wood base fits into several layers, so it is important that the base is strong enough

The first layer of roofing material is heated from the inside out and placed on the wood surface. The upper layers of stacked roofing standard, i.e., a fusing.

If rubemast broke - it does not matter, because it can be quickly and easily repaired

As already mentioned, rubemast, like all roll coating, deteriorating rapidly. What if there was a crack in the roof?

The essence of the repair is to install patches and these patches can be put a lot

In spite of low strength, good rubemast its maintainability. That is, if you noticed the damage can be repaired. For this purpose, a piece of material that it extends over the damaged region 10 cm.

Around the damaged surface lubricates bituminous mastic. Rubemast prepared to put mastic and smoothes.

To summarize

Now that you know how to lay rubemast and able to cover the roof yourself. Write about your experience in the comments repair the roof. Also, watch the video in this article, I am sure you will be interested.
