How to use roof membrane.

Membrane roofs are most commonly used in commercial application though they are becoming increasingly common in residential application. However not every material that prevents leaks can be considered a membrane. Try the pieces of rubber on the roof before using any adhesive to check that they all fit. First and foremost roofing membranes exist to prevent water from leaking into your home.

They are usually installed with thicknesses anywhere from 30 to 60 millimeters. For example many roofs today are protected from the elements by a few layers of asphalt. The first step in waterproofing a roof is cleaning of the substrate. Position the epdm membrane.

Use scissors to cut out the sections of rubber. Roofing membranes are also categorized by thickness in millimeters. You might need to cut more pieces of rubber or trim existing ones. It is used to create a watertight roof covering to protect the interior of a building.

Cut the membrane and turn it so that it folds up against the penetration. Roof penetrations around chimneys soil pipes etc. Leave the material for the next 20 30 minutes to let any folds or creases fall out. Use the measurements to calculate how many sections you will need to cut out in order to complete the project.

At abutments the underlay should be turned up by at least 100mm this will create a secondary water resistant barrier. If needed tape the cut out sections to the penetration to prevent them from folding back down. All successful liquid applied membrane applications require superior adhesion. For round penetrations cut the membrane with an asterix shape to create flaps to fold upwards.

A typical application of liquid applied roof membranes consists five main steps which should all be treated with utmost importance following the product manufacturer instructions. Cleaning priming treatment of details main coating application and inspection. The material can now be rolled out and laid into the required position across the surface of the roof.
