WATERPROOF COATING SERIES

YWM-124 Primer of substrate used for bituminous waterproofing sheet

Waterproof coating ranges

————

The product is a bonding agent special used for asphalt membranes; it is made of asphalt, rubber and a variety of additives. It can be used for bonding between membrane and substrate and between membranes to form sealing and waterproofing.

PRODUCT

INTRODUCTION

FEATURES

PRODUCT

Liquid cold construction, easy operation.

①

Fast drying, strong penetration, improve the bonding strength between the membrane and the substrate or between membranes.

②

It will not fall off at high temperature, and it will not embrittle at low temperature.

③

It does no contain benzene solvent; it is safe and reliable and will not burn in liquid state.

④

1, Before construction, squeeze the binder bag evenly and use it
2.Unfinished primer should be timely sealed, in case leading to product thickening and affect the construction
3.When constructing at low temperature, the primer should be insulated, using on demand.
4. Reference amount:0.4~0.5kg/㎡.

Notices

●When used as Primer of substrate: the substrate must be firm, smooth, clean and dry; no peeling, sand, holes, cracks and other defects. Use a rolling brush or scraper to coat the primer evenly on the substrate to ensure that the substrate is all covered, and not piling up; covering the membrane products when the primer is dry and not stick hands.
●When used as a binder of protective waterproofing membrane : use the scraper or shovel to evenly coat the primer on the non-woven surface of the overlapped position of protective waterproof membrane, to ensure that the substrate is all covered, and not piling up; covering the membrane products when the primer is dry and not stick hands and compacting the overlap of membrane.
