Bitumen Rubber Based Elastomeric Liquid Membrane - BLM 117

Description

BLM 117is a ready to use single component liquid bitumen solution with highly elasticising additives.

After application the solvents evaporate andBLM 117becomes an elastic strong layer agaist water.

Usage Areas

BLM 117can be applied against ground humidity, percolating water, moisture and leakages at building exterior surfaces,

balconies, roofs, terraces and foundations, at retaining and curtain walls, galleries, drainage and foundation piles, hidden

internal valleys , water channels and pools.

In higher pressure applications,BLM 117can be applied with glassfibre or waterproofing fabric reinforcement as well.

BLM 117can be applied for regeneration on old bituminous roofing membranes.

Advantages

It is very easily applicable by anybody.In comparison to conventional bituminous waterproofing materials, it is much more

resistant to atmospheric conditions.It is highly elastic. (900% min.) Higher-pressure applications are possible by using

glass fibre or waterproofing fabric reinforcement as well.BLM 117ensures a seamless insulation on vertical or horizontal

surfaces where it is applied. It is ready to use. No heating or thinning is required. It is cold applicable and dryes fast. Very

economic. It is highly adhesive on most building materials and metals.

Surface Preparation

Surface must be dry and clean before application.Any loose pieces, dust, oil, grease should be removed.

Sharp tips and horizontal/vertical joints which are suitable cracking, must be chamfered. On metal surfacesB PR 102,

on non-metal surfacesB PR 101shall be used as primer to clean from dust, to improve adhesion and therefore improve

life of application. Big pores and cracks must be filled withREPAMERKrepair mortar.

Application

BLM 117shall be applied to that surface of the wall, which will be in contact with water (positive pressure). It is ready

to use. No heating or thinning is required. It can be applied by brush or airless sprayers.

AlthoughBLM 117is a fast drying type of solution (2 hours approximately), every next layer should better be applied next

day. To obtain higher resistance or in case of cracks glassfiber or nonwowen polyester-fleece can be used.

For exposed and non-walking roofs,ALUCOATshall be applied as topcoat, so a solar protection and aesthetic look may

be obtained.

Tools Cleaning

After application, tools can be cleaned with solvents.

Consumption

At least two layers and a total of 1,5 kg / m²

Packaging

Net 17 kg metal buckets
