Cold liquid applied systems

Our cold liquid applied systems are based on the most advanced PMMA technology. They are simple to install, fast curing and long lasting; making them suitable for use in all kinds of flat roof, balcony, walkway, and terrace waterproofing and surfacing applications.  All our cold liquid applied systems meet current UK Building Regulations Part B for External Fire Protection.

  • LiquiTEC Roof

    Project: New build or refurbishment
    Construction: Warm, cold, inverted
    Upgrades: Green roofs


A cold liquid coating cures to form a rubber-like elastomeric waterproof membrane. It’s capable of stretching and returning to its original shape without damage and proves a cost-effective method of making a new or existing roof waterproof. Bauder Cold Liquid Applied Systems are based on the most advanced PMMA technology, which allows exceptionally fast installation curing times compared to other systems available. They are simple to install and long lasting; making them suitable for use in all kinds of flat roof, balcony, walkway, and terrace waterproofing and surfacing applications.

All our cold liquid applied systems meet current UK Building Regulations Part B for External Fire Protection. LiquiTEC holds BBA Certification 14/5152. They are available in three colour finishes: stone grey, blue grey and traffic grey.


Why Cold Liquid Applied systems?

Liquid roofing systems encapsulate the surface they are applied to, preserving whatever is underneath and protecting it from weathering. Life expectancy 25 years Cold Liquid Applied Systems have rapid curing times, even in winter and a life expectancy of up to 25 years if maintained correctly. Other benefits include:

  • Excellent adhesion to all kinds of surfaces.
  • Chemical resistant.
  • High resistance to extreme temperatures.
  • Completely waterproof and no heat or special equipment required.

The installation of liquid roofing does not involve hot works. The coating material used in the liquid roofing process is applied cold, thus negating any fire risk.

Bauder work hard to ensure all our products meet the latest criteria for various accreditations.


Installation and Maintenance

Bauder Approved Contractors are the only people fully trained and certified to install our products, providing the necessary experience that our exceptional guarantee demands.

To keep the roof in prime condition, practical maintenance should be carried out. This includes:

  • Cutting back tree limbs that overhang the roof to give a 1 metre clearance outside the roof edge. This will reduce blockage of drainage ways due to fallen leaves.
  • Removal of any vegetation growth that may have occurred, taking care not to damage the waterproofing.
  • Ensure that any protective metal flashings and termination bars remain securely fixed in place, repair or renew as necessary.
  • Examine all mastic sealant and mortar pointing for signs of degradation, repair or replace as necessary.
  • Where promenade tiles or pavers are in use, ensure that they remain in position, secure and in good condition.

Should the system require cleaning, the following methods may be used:

  • Manually washing down with a solution of warm water and approved detergent.
  • Pressure washing with a cold or warm water pressure wash with approved detergent in solution. The head of the water lance should be kept at least 500mm away from the surface and pressure should be restricted to less than 1500psi.
  • Rinse the surface with clean, cold water.
  • Water temperature should not exceed 50°C Use only mild detergents or degreasants.

Cleaning methods and materials not in accordance with Bauder guidelines may affect any warranty. When manually washing rough surfaces, consideration should be given to using mop heads specially designed for this purpose.


Green Credentials

Cold Liquid Applied roofing systems can be used for green roofs as the system formulation delivers superior root resistance. Manufactured under ISO 14001 Environmental Management System, all cold liquid applied products are solvent, isocyanate and halogen free and have a BRE Green Guide Generic A Rating (A+ to E scale) for PIR insulation.

Which System is Right for my Project?

There are two Cold Liquid Applied systems available to use. Contact Bauder’s friendly team of experts to find out which one is best suited for your project.


LiquiTEC Roof System

Warm roof options involve four layers:

  • BauderTEC KSD DUO a self-adhesive carrier membrane and vapour barrier.
  • Bauder FA-TE insulation a foil-faced highly efficient rigid PIR board for warm roof construction.
  • Another layer of BauderTEC KSD DUO.
  • A final layer of LiquiDEK, a fast curing waterproofing resin with reinforcement.

Cold roof options involve two layers:

  • A concrete or timber deck.
  • LiquiDEK, a fast curing waterproofing resin with reinforcement.

LiquiTEC Balcony, Walkway and Terrace System

This consists of three layers:

  • LiquiBALKON a fast curing resin for use on the main area waterproofing for balconies, walkways and terraces.
  • LiquiPAVE RF a filter component.
  • LiquiFINISH the fast-curing final coat used to seal and bind the quartz wearing course.

Cost savings are made through quick installation times and all system elements are totally cold applied, avoiding the inherent risks associated with hot works. Both LiquiTEC Roof System and LiquiTEC Balcony, Walkway and Terrace System uses an exceptionally fast curing PMMA resin. Products are solvent, isocyanate and halogen free.

We have case studies and examples of our work available for you to look at, including the application of a Cold Liquid System in Hackney. Of course, each project is unique in its requirements.
