Description:

Graffiticoat is a 2 pack exterior / interior pigmented or clear urethane that has excellent non-yellowing exterior durability, and is designed to facilitate the removal of graffiti from its surface without effecting the substrate.

Graffiticoat's 100% crosslinking characteristic makes it extremely chemical resistant.

Graffiticoat contains sophisticated silicone additives that prevent permanent adhesion of subsequent grafiti.  With the assistance of a chemical cleaning solution, this graffiti can be removed without effecting the protected substrate.

Suggested Uses:

Graffiticoat is particularly suited to overcoat residential and commercial buildings constructed of pre-cast concrete, concrete, bricks, fibre cement sheeting, metal claddings, cement plaster including concrete blocks.  etc.  DO NOT use on cedar or soft timbers.

Sealer / Basecoat Application To:

Concrete or block fibre cement (hardiflex / harditex) buildings, etc.

Apply 2 coats of Aquepoxy in colour required, then apply 2 coats of Graffiticoat.

Alternatively, apply 1 coat Strongwall Acrylic Sealer, 2 coats of Sprayflex Hi Build.  allow to dry.  then aply 2 coats of Graffiticoat.

These systems will provide optimum weatherproofing and flexibility on concrete, fibrolite and block buildings.
