Cold applied liquid
Our cold applied liquid systems are based on advanced PU and PMMA technology. They are simple to install and long lasting; making them suitable for use in all kinds of flat roof and surfacing applications. All our cold applied liquid systems hold fire classification BROOF(t4) for compliance with building regulations under TS 1187 test method 4 for external fire exposure to roofs. LiquiTEC holds BBA Certification 14/5152 and LiquiTOP holds BBA Certification 20/5789.
A cold applied 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.
Why cold applied liquid systems?
Liquid roofing systems encapsulate the surface they are applied to, in refurbishment applications preserving whatever is underneath and protecting it from weathering. Life expectancy is up to 25 years depending on the chosen system. Other benefits include:
Excellent adhesion to all kinds of surfaces.
High resistance to extreme temperatures.
Completely seamless waterproofing.
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 works hard to ensure all our products meet the latest criteria for various accreditations.
Installation and maintenance
Only fully trained and certified Bauder Approved Contractors are allowed 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 which reduces 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 mild detergent.
Pressure washing with a cold or warm water pressure wash with a mild 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.
The Bauder LiquiTEC cold applied liquid roofing system can be used for green roofs as the system formulation delivers superior root resistance. All our cold applied liquid systems are manufactured under ISO 14001 Environmental Management Systems and have a BRE Green Guide Generic A Rating (A+ to E scale) for PIR insulation.
