Identify the ponding area and mark an outline on the roof surface with paint. Thoroughly clean the area and make any needed repairs to ensure a good bond. Make sure the area is dry. Note: Pressure washing or cleaning with an all-purpose cleaner can help with extremely dirty areas.


Note: mix the material after priming. Pour the small 6ml accelerator provided into the 500ml primer and mix thoroughly. Apply the primer onto the ponding area earlier outlined with the paint brush provided BUT make sure you paint the primer on an extra 50mm round the edge of where the Greenslope will end.


Pour the larger 16ml bottle of accelerator into the 1L of binder and mix/shake very thoroughly so that the accelerator has a chance to mix with all of the binder. Pour all the rubber granules, polystyrene beads, binder and any excess primer (if there is any), into the mixing bag, seal with the cable tie and mix everything at once, usually only takes 4-5 minutes to mix. We recommend rolling the bag on a smooth surface to get the best mixture. If you only need a small amount, mix in the bucket.

Spread & Compress:

Open the bag and pour the contents over the desired area and spread the mixture using a trowel or straight-edge. Wet the trowel in solvent to stop the components sticking. We recommend using a spirit level to check that you have spread it to the gradient desired. IMPORTANT; It is essential to compress the material thoroughly using the trowel, especially around perimeter to minimize water infiltration and make a smooth surface for the top coat. Wait until the Greenslope is dry before applying the top coat. Note: If it looks like it might rain before you can apply the top coat, make sure you cover it well so that no water can get in as it won’t be able to drain away.
