Product Overview

SikaShield W1 IN is a one-part, polymer-modified cementitious adhesive designed to bond SikaShield W bituminous membranes to concrete substrates. Supplied as a powder that requires only the addition of water, it develops strong adhesion between the membrane and concrete while tolerating wet or matt-damp surfaces, which makes it well suited to below-ground conditions where substrates are rarely fully dry. It needs minimal surface preparation and offers good mechanical strength once cured. The adhesive is used in basements, on horizontal reinforced-concrete slabs, decks and podiums, and on vertical walls. Space Arc Engineering, an authorized Sika distributor in India, supplies SikaShield W1 IN together with the matching membrane system and application advice for infrastructure, industrial, commercial and residential waterproofing.
