You can think of 3C Liquid Jacket Liquid Rubber Membrane as a thickened paint material which is still runny enough to treat like a paint when applying it to various surfaces. Many people like the control of a small roller when doing flat horizontals and verticals such as internal walls and floors to tank a shower area for instance, whereas, fittings such as upstands around skylights on a flat roof or surrounds and fixtures around pipework channels, connecting joints from one surface to a different surface would benefit from the material being brushed on as you can get to the nooks and crannies essential for making the whole thing waterproof. Another popular option is using a flat tool such as a spatula or rubber-bladed squeegee to plaster the Liquid Rubber Membrane on and smooth it off.

Any of the above are more than adequate so it comes down to the individual application and user choice.

As there's various ways to apply 3C Liquid Jacket Liquid Rubber Membrane, it's difficult to exactly specify an adequate thickness but the standard would be around 1mm minimum and 3mm maximum with a coverage of 1 x tub (6kg) providing approximately 4m² @ 1mm thick.

The best way to decide how thick to apply is to think about the application in layers. The most important factor is that the whole surface to repair, protect or waterproof is fully covered. You can apply the rubber membrane in one or more layers with the second layer being applied after the first layer is completely dry.

Although 3C Liquid Jacket Liquid Rubber Membrane goes on and adheres very well to various types of bitumen, asphalt or mineral felt type surfaces, it's notoriously tricky to coat these types of materials as they tend to react to any foreign bodies coming into contact with them.

With this in mind we don't fully invest in the positive advice of using this product on such surfaces as a total covering solution (i.e. reinstating flat roofs etc.) but instead suggest that Liquid Rubber Membrane can be used to repair cracks and splits in roofing felt etc. and/or belt and braces cover upstands, fittings and fixtures, lead skirting's etc. As with all wet construction products, applying the material to a small inconspicuos test area is recommended before embarking on any type of job!  

That all said, we have tried and tested it several times on various roofing felts and bitumen surfaces with success and no bleed out or reaction so give it a go and let us know 🙂
