Product overview

Preparing the substrate

Use WP-ACC-000001 before the bonding adhesive in an EPDM waterproofing system. On suitable porous substrates, it seals pores and binds fine dust to prepare the surface for adhesive contact. It does not replace repair of severely friable or crumbling surfaces.

Application sequence

Confirm the primer and preparation method for the substrate.
Check that the surface is dry and repair loose or crumbling areas.
Brush the primer over the surface without gaps or local build-up.
Let the coating dry until it is no longer tacky to the touch, then apply the compatible bonding adhesive.

Ask us to confirm coverage, any mixing requirements and drying conditions for your substrate before planning the work.

Choosing the adhesive

WP-ACC-000002 EPDM bonding adhesive is the related product for main-area bonding. Send the substrate and membrane details so we can check the primer-and-adhesive combination for your installation.

Ordering options

How sourcing works

Identify the substrate: Tell us whether the surface is concrete, cement mortar, metal or another material, and describe its condition. Product suitability and preparation requirements must be confirmed for each substrate.
Plan the application: Share the treatment area and proposed bonding adhesive. Confirm coverage, any mixing requirements, application conditions and drying time before estimating consumption or scheduling work.
Request a quotation: Specify WP-ACC-000001, the required quantity and delivery destination. Include sample, packaging and technical-information requests; MOQ, lead time, storage conditions and shelf life require confirmation.

Questions before you order

Is this the same as an EPDM seam primer?

No. This primer treats the building substrate before main-area bonding. Seam primer treats the EPDM surface at joints and details.

Can I use it on concrete, mortar or metal?

Ask us to confirm suitability for your exact substrate. Metal needs its own preparation and compatibility review; pore sealing and dust binding apply to porous substrates.

Can I prime a damp or crumbling surface?

No. Let the substrate dry and repair loose or crumbling areas first. Confirm the required moisture, strength and cleaning conditions for the surface.

When can I apply the bonding adhesive?

Wait until the primer is dry and no longer tacky to the touch. Ask for the drying time and application conditions for your selected system.
