How clean does the surface have to be?

If there is any dust or dirt on the surface the system will bond to this. Ensure the surface is fully clean by using a high pressure jet wash or similar cleaning method.

Ultimately, each project is unique, and it’s down to the applicator to decide the best method of cleaning for that specific surface.

What can I clean my brushes or roller in?

We strongly advise disposing of brushes and rollers after each use, this avoids any contamination occurring in the membrane and ensures a uniform finish. Due to this we advise using cheap brushes and short pile rollers.

How to store opened tins?

Keep containers upright and tightly closed when not in use and keep from extreme temperatures.


Can we apply different layers on different days?

Rapid Roof does not have to be applied in one day. You can apply different layers on different days if it is necessary. It is advised to always clean the surface before application of the next layer if there has been such a break from application.

Do I need to use a flashing or termination bar?

RapidRoof is a self terminating system so it can be finished under or on any existing flashing. If terminating on a parapet wall, finish halfway up a clean and dust free brick course.

Can I slow down the curing process?

Using less or more catalyst can affect the curing process, but it may also cause an uneven and incomplete curing of the membrane. We advise to always stick to the prescribed catalyst to product ratio.

How long does it take to cure for foot traffic?

Cure For Light Foot Traffic: 1 hour 20°C. Vehicular Traffic: 2 Hours 20°C. Full chemical resistance: 24 hours @ 20°C.

The catalyst ratio equates to 2% of the main product, 20g of catalyst to every 1kg of product.

What’s the shelf life?

RapidRoof has a shelf life of 12 months when stored in original unopened containers.

What to do if it rains?

Always check the weather forecast in advance. But for circumstances where rain is an immediate problem, what to do if it rains is stop application immediately.

Any product applied on a wet surface risks not bonding correctly.

If within the 20-minute curing window, cover up your existing work and wait for a good dry spell to continue. Thoroughly dry the coat between applications.

Elasto-Kote becomes showerproof in 40 minutes but will take up to 24 hours to become fully cured. We advise leaving 24 hours between applications.

Elasto-Kote is typically showerproof after 40 minutes depending on the weather conditions.
