Liquid Flash 1 o ers longevity and resilience

As compared to sheet membranes, cold fluid-applied waterproofing membranes can create a "monolithic" barrier to water, without seams. They are easy to apply around complex shapes, including areas with multiple penetrations, intrusions and transitions.

Liquid-applied membranes not only deliver a superior waterproofing barrier, they also save time on the construction site. With efficiency increasingly important everywhere in construction, these membranes have rapidly become the "go to" solution for most builders.

Dribond Construction

Chemicals' Liquid Flash 1 is a reinforced, brush-applied waterproofing membrane that ranks as one of the industry's leading products in this category. It is a premixed, one-pack, waterbased, microfibre reinforced acrylic, flexible, waterproofing membrane that is easily applied with a brush to form a resilient waterproof or flashing membrane between different building surfaces.

This is a highly versatile product. It remains pliable and elastic, and is capable of bridging cracks, as well as smooth irregular surfaces. It provides excellent resistance to UV light, which means it will continue to function over a long time period even in exposed conditions. Liquid Flash 1 comes in two base colours, grey and blue, and can be painted over with water-based acrylic paints.

As Liquid Flash 1 conforms to AS/NZS 4858 Class 3 it features high extensibility; it is a membrane that is suitable for timber-framed and timber floor construction where there may be considerable movement. The product even exceeds the SISIR (Singapore) requirements for rooftop waterproofing.

Properly stored and unopened, Liquid Flash 1 has a shelf life of up to 24 months.

Uses

Liquid Flash 1 is a waterproof membrane for roofs, balconies, retaining walls, planter boxes, internal wet areas (e.g. bathrooms, kitchens, laundries and toilets). It can be used as flashing material for roof vent pipes, parapet walls and roof sheeting/tiles. It can also be used on cement render, concrete, brick, block and building boards such as gypsum and cement sheeting on walls and compressed cement sheeting on floors, roof and gutter repairs. The product is suitable for uses such as shower alcoves, and should be allowed to cure for three days prior to tiling. When pond testing shower installations, it is recommended that the product be allowed to fully cure over seven days before testing.

If the product is to be used in a fully-immersed application, it should be allowed to initially cure for 28 days. In general, curing takes seven days at 23C with 50% relative humidity, and should be protected from rain during the first 24 hours of curing. The product should be fully cured before use in a shower application.

Application

Apply two coats of Liquid Flash 1 to the area to be waterproofed. Apply the second coat at 90 degrees to the first as soon as it is dry (recoat time is approximately two hours at 23C and 50% relative humidity). Apply each coat thickly (approximately 1.5mm wet), allowing it to flow rather than being brushed on. Use a soft brush for best results. A final thickness of 1.5mm is required. n
