Liquid Rubber Membrane
ISONEM BE 89 is a 700% elastic liquid bitumen, rubber modified coating. After drying, it forms a waterproof coating on applied surfaces. High elasticity and crack hiding property. Suitable for insulations of old or new roofs and use under the ground, but it is not affected by underground waters. It strongly adheres to dry or slightly moist surfaces. It does not swell or peel of over time. Resistant to the plant roots. Also suitable for use in garden & terraces.
Surface preparation: Application surfaces should be dry or slightly damp. It should not be used in insulations which is from the negative side and on the basement wall where is appeared salt efflorescence. Application surfaces should be cleaned from all kinds of particles, dirt, a bonding agent, dust, mud. Firstly, gap, hole, crack and segregation on the surfaces should be repaired with ISONEM M03 elastic mortar by using ISONEM D10 Latex as bonding agent. If there is dilatation, it should be filled with ISONEM A4 Elastic Filler. As a primer, ISONEM BE 89 is used as diluted with water 1:1. The primer is impregnated to surface via a hard brush and waited to dry completely. For applications on terraces and roofs, R-3 cm chamfer should be applied to the walls and parapet bottom before this process. In terrace and roof applications, it is recommended to lay an insulating mesh of 45 gr/m² and the application should be done with it. There is no need for mesh in the basement.
Application method: Ready to use. It should be mixed homogeneously before application. ISONEM BE 89 is applied by brush or roller without diluting to the surface 2-3 layers and waiting to dry between the layers. The application should be made in perpendicular layers each time. It is recommended to use the 45 g / m² insulation mesh between the floors in terraces and roofs or on floors with high risk of cracking. Application should not be made in high temperatures or frost. In summer, we recommend that the application be done in the morning or evening. It should be ensured that the roofs on which the application will be made are given the correct and sufficient slope for suitable water drainage Suitable water drainage. In order to avoid ponding on the roof. It is recommended to use with grout detail in chamfer applications.
