TECHNICAL INFO

Technical Info

RUBBERSEAL LIQUIFLEX®-PRO is a high performance, wet-on-wet, cold applied liquid waterproofing system that is fully reinforced with a polyester fabric. It has significant advantages over conventional liquid roofing systems because it can be applied wet-on-wet, is a single liquid product, fume free and virtually odourless.

LIQUIFLEX®-PRO has many advantages over traditional types of waterproofing particularly within the refurbishment sector. As well as being cold applied, LIQUIFLEX®-PRO offers a seamless roof finish. It forms a permanently elastic, seamless membrane and is ideal for long term waterproofing of awkward roof details such as pipe penetrations, upstands and gutters. These characteristics also make the system a perfect choice for the long term protection of balconies, terraces and patios.

LIQUIFLEX®-PRO will bond to most substrates, allowing its use in many situations without having to remove and dispose of the existing roof covering. This saves time and avoids the cost of removal and environmental issues associated with disposal.

LIQUI-PRIME 5L tin
LIQUIPRIME

DESCRIPTION

Liquiprime is a single component, low viscosity primer. It has been specifically designed to increase bonding and improve the surface levelling of some substrates prior to the application of the Liquiflex®-Pro.

Liquiprime can be applied with roller or brush straight out of the tin at a coverage rate of 150-200ml per m2.

Tin size is 5Ltr (Therefore minimum coverage of 25m2 can be achieved).

Liquiprime is translucent with excellent bonding onto porous surfaces.

IMPORTANT:

If the surface to be treated is uneven in  places, areas can be built up by using a coat of Liquiprime mixed with silica sand to level it, prior to applying a full coat of the primer.

DRYING TIME

Tack time: 60 mins (20C) – Wait until completely dry before applying Liquiflex-Pro.

NOTES:

Liquiprime must be used on all concrete substrates, TPO single ply and any rubber outlets.




LIQUI-TOP 5L tin
LIQUITOP

DESCRIPTION

The use of Liquitop is recommended to increase UV stability, for trafficable areas or achieve extended guarantees.

INSTRUCTIONS & COVERAGE

Liquitop is a single component top coat applied at a coverage rate of 150g/m2 per sqm in one layer to cover around 5sqm per litre.

DRYING TIME

Liquitop has a drying time of 2 hours once applied.

NOTES:

Liquitop must be applied no later than 48 hours after Liquiflex was applied and on a clean and dry surface.

For carparks and high traffic areas Liquitop HT should be used.

LIQUI-CLEAR 5L tin
LIQUICLEAR

DESCRIPTION

Liquiflex® Clear is a single component, aliphatic–UV resistant transparent coating that can be used for waterproofing of roof lights, lead, copper or in general to protect the aesthetic look of any roof. Liquiflex® Clear is also recommended to encapsulate mineral slate in anti-skid finishes, providing a tough, sealed, trafficable surface.

INSTRUCTIONS

Liquiflex® Clear has a pot life of two hours and drying time of 1-2 hours based on weather conditions.

Liquiflex® Clear can also be used as a temporary waterproofing / primer for OSB or plywood decks when used in conjunction with Liquiflex® matting.




LIQUI-THIX 1L tin
LIQUITHIX

DESCRIPTION

Liquithix can be added to Liquiflex-Pro membrane to thicken the liquid when going onto vertical surface areas.

Thickening the liquid can help to avoid runs and drops, or sagging of the re-inforcing matt.

INSTRUCTIONS

Liquithix can be mixed to Liquiflex-Pro at ratio of 100ml – 500ml per 15kg tin, depending on requirements.

NOTES:

Liquithix should not be confused with an accelerator as it does not affect the membrane curing time or process.
