RapidRoof Pro Gutter - Liquid Waterproofing Gutter System

Once the surface is cleaned and fully prepared, RapidRoof Pro Gutter liquid waterproofing can be applied using a short piled roller or brush. Surface temperature during application must be between 0°c and 35°c. RapidRoof Pro Gutter should always be applied in 2 coats. All areas must be fully primed using RapidRoof Primer and RapidRoof BaseCoat should be fully reinforced using 150gsm reinforcement matting.

Cleaning the substrate

LRS recommend the use of a minimum 2000psi pressure washer to ensure the surface is suitably cleaned. If pressure washing is not possible, the contractor must deem the most appropriate method of cleaning that achieves a similar clean to that of a 2000psi pressure wash.

A clean and dry surface is critical for a successful bond of the RapidRoof Pro Gutter system, if the surface is not sufficiently cleaned, RapidRoof Pro Gutter will bond to this rather than the substrate it is intended for.

Fully prepared substrate

Ensure the substrate is fully prepared before applying any

RapidRoof Primer or RapidRoof Waterproof. All joints that are over 3mm should be filled using RapidRoof Multi Purpose filler or RapidRoof Pro Detailer. If these joints are not filled, this could lead to pinholes within the waterproofing membrane.

All surfaces should be checked for cracks and damage, and repaired where necessary. Any repairs made using water-based concrete/sand cement will need to be completely dry, which is typically 28 days. Using RapidRoof Multi-Purpose Filler will reduce this time to one hour.

Detailing

All details must be completed first before the start of the main waterproofing application. Upstands should be detailed up to a a minimum of 150mm where possible. Any details that do not meet the 150mm height requirement would need to be terminated either using a termination bar or LRS PU Mastic.

All joints/vulnerable areas should be reinforced using RapidRoof Pro Detailer.

RapidRoof Pro Detailer should be applied over the joint to fully encapsulate the fixings and joints at 150mm wide strip.

Snagging

Once the detailing is complete the gutter should be snagged to remove any wicks and debris created in the detailing stage of the application. This can be done by lightly sanding the wick to remove it with 80 grit sandpaper or similar.

RapidRoof BaseCoat

RapidRoof waterproofing should be applied to all details and the gutter. This must be done in 2 coats, RapidRoof BaseCoat should be applied at a coverage rate of 1.25kg per m² using a short piled roller, and fully reinforced using 150gsm Reinforcement Matting.

The Reinforcement Matting must be fully saturated and

embedded, making sure the membrane is free from

creases and pinholes. Ensure the RapidRoof tins are gridded out over the gutter area to allow an accurate application at the prescribed coverage rate.

RapidRoof TopCoat

RapidRoof TopCoat should be applied at a coverage rate of

0.75kg per m², ensure the tins are gridded out to achieve

the correct coverage rate.
