Flexible, long-lasting waterproofing for trade and DIY

Although liquid polyurethane is not a brand new concept, Permaroof has taken the idea a step further in the introduction of our latest roofing system. Developed with a long-term solution to reliable waterproofing for domestic, industrial and commercial properties in mind, our liquid waterproofing system has wide benefits over a range of uses.

Manufactured with a polyurethane base, our synthetic liquid rubber solution covers even the most complex areas and offers complete waterproofing over a variety of surfaces. The system uses a base coat, Permaband reinforcing matting and a topcoat with UV protection and also can be used create anti-slip surfacing with addition of a suitable medium. We stock a range of Permaband reinforcing mat sizes to suit all types of installation and coverage requirements – 120m rolls are available in 100mm or 200mm widths or 50m rolls of 1m width for main surface area coverage.

Flexible, long-lasting waterproofing for trade and DIY

Liquid polyurethane (liquid rubber) roofing with Permaroof500 is super-smooth and fast. It cures quickly and is effective immediately, which makes it ideal for fast repairs or roofing replacement. Permaroof500 needs few tools for application. Safely and quickly apply a single coat of liquid rubber using a foam roller. Brushes or small rollers can be used for detailed areas. The product contains a self-levelling compound so does not have to be overworked. (It is suitable for pitched roofing with the addition of a solution to remove the self-levelling properties). The UV topcoat is applied using the same method to seal and protect the rubber roofing and improve weatherability.

When creating an anti-slip surface, such as a car parking zone or to make safe slippery garden steps and paths, use a recommended medium for the best results. This can be mixed with the liquid rubber solution or for a more even spread and finish, sprinkled across the still-wet surface.

Careful attention should be paid to the edges of any flat roof installation to make sure that the project is kept reliably watertight. This is true of both sheet membrane and liquid rubber roofing. Facias and soffits should be masked off if necessary to avoid drips and spots of the product.

Once the surface is cured, the best way to finish off is with roofing trims. These complete the seal around the edge of the installation and create a professional looking, neat finish that will keep the edges tidy over the long term. We stock a range of hard-wearing trims ideal for the liquid waterproofing system.
