ESHALAC 50S | Bituminous Varnish / Primer

Low-viscosity penetrating varnish, primarily used as a primer for concrete surfaces prior to the torch-welding of bituminous membranes.

The ARGYNET View: This is ESHA’s ‘classic’ solvent-based primer — it requires a full drying time of ≥24 hours before the membrane is applied, and, due to the solvent content, it must only be applied in open/ventilated areas.
