Waterproofing Product for Roof & Gutters

Waterproof Coatings for Rooftops

Finding a waterproofing solution is not just identifying the roof leak but also using quality products together with correct methodology to fix the problem.

There are a multitude of waterproofing products on the market however not all are suitable to use as a roof membrane and particularly for roof repairs & remediation.

Traditional sheet waterproofing methods involve joins/seams which require fastening or glueing down - these are areas of weakness that may lead to water leaks in the future.

And there are roof waterproofing products that use flames, heat, fumes and Volatile Organic Chemical (VOCs) which are not suitable for application in the DIY market.

Waterproofing Membranes 

Fix Roof Leaks Easily!

Liquid Rubber is a versatile repair product for patching leaks in roofs, repairing cracks along parapet walls and flashings and sealing around roof penetrations associated with skylights, rooftop air conditioners, and pipe work and is an extremely effective sealant to repair box gutters.

It's the easiest system to apply because you just paint Liquid Rubber on.

• Cost Effective

• No flames

• Proven Technology

• Flexible - allows for roof movement

• Elasticity of 1100%

• Speed of Application

• Total bond to roof

• Environmentally Friendly

Roof  Waterproofing Membranes 

Liquid Rubber has the following properties:

· Flexibility – membranes moves with normal climatic fluctuations of roof expansion and contraction.

· UV Stable –  membranes is  UV resistant- long life.

· Robust Adherence – membrane has strong bond to existing  roof surface -metal, concrete, timber & asbestos.

· Contours to Shape – rooftops often involve air conditioning utilities, skylights etc. A Liquid Rubber waterproofing membrane seals around all roof penetrations.

Surface Preparation Prior to Waterproofing Application

As with all waterproofing membranes, the surface must be dry and free of anything that could adversely affect adhesion.

→ You should be sure to remove all loose, scaling, peeling, blistering, chipping, cracking, chalking or gravel, dust, dirt, sand, soot, grease, oil, uncured tar, wax, soap film, animal fats or petroleum-based residue, coal tar, chlorine, salts, efflorescence, or any other chemically reactive substance (solvents) that may affect adhesion.

→ Wire brush or if needed high-pressure water blast should be used to thoroughly clean all surfaces prior to application if any of the above conditions exist.

→ Surface should be free of mould, mildew, dirt & as dry as possible.

→ Mildew and similar growths can be killed with 1 part household bleach to 2 parts water, followed by a thorough rinse with clean water.

→ All surfaces must then be allowed to THOROUGHLY DRY before proceeding with application. 

LIQUID RUBBER typically cures within 24-48 hours (depending on application thickness, temperature, and relative humidity).

You will notice the product is touch dry with-in 2-3 hours, however the Liquid Rubber is still going through a very important process called “curing” which may take one to several days to fully complete.

• Curing is the process when the Liquid Rubber becomes a single flexible membrane.
• Once cured, Liquid Rubber can contain water on a permanent basis.
• So Liquid Rubber is ideal for ponds and water features.
• This process can take between 5-7 days in warm weather or longer if moisture is held within.

If “active” water is trying to push through a wet membrane – it will not cure. i.e like concrete with water saturated through the porous material.

Blistering can occur if vapour is trapped in substrate. Allow blisters to dissipate over time- repair if holes occur.
