How to Apply
It's easy to attain a long-lasting spray cork coating by following these instructions.
Inspect for asbestos. If present, contact your local government agency about proper remediation and protection.
Remove rust and/or loose paint with a wire brush or power tool.
Clean the surface thoroughly with a pressure washer.
Repair any cracks, holes and voids in excess of 1/8”.
Tighten screws and other fasteners.
Seal screw holes and other penetrations in metal cladding.
Allow surface to dry (from 6-24 hours, depending on ambient humidity and temperature.)
Mask and protect adjacent surfaces you don’t want coated. Lay down tarps to protect underlying grass and landscaping.
Dilute and mix Universal Primer: 4 parts water to 1 part primer.
Apply 1st coat by roller or spray application. Let dry for 4-5 hours.
Apply 2nd coat. Let dry for 4-5 hours.
Mix Spray Cork
Open 12kg pail of SprayCork.
Add 1 bottle Inkercork colorant per 12kg pail of SprayCork.
Mix with a mixing paddle at 800rpms for approximately 2 minutes until colorant is uniformly dispersed.
Add 300ml to 1L (10-32 oz) of water gradually, depending on local weather conditions. Higher temperatures and lower humidity require more water.
Important: add the same amount of water to each pail to ensure uniform consistency.
Mix again for minimum 2 minutes until a smooth consistency is attained.
Allow mixture to rest for 5 minutes before spraying.

Wet hose and prime system in accordance with Operating Manual.
Pour spray cork mixture into hopper.
Close prime valve. Open air control valve.

Adjust air control valve and flow adjustment nut on gun until a uniform spray pattern is achieved.
One 12kg pail of Spray Cork will provide coverage of approximately 6m2 / 65ft2. Do not apply spray cork during rain or high winds. Apply between ambient temperatures of 5-35 degrees Celsuis.
Apply first coat of SprayCork at a uniform thickness of 1-1.5mm, spraying 40 – 70 cm from the surface in horizontal movements at 60-70 psi. Allow 6-24 hours to dry.
Apply second coat using the same technique and allow to dry 6-24 hours.
Apply a third, very thin layer at longer distance using a circular pattern to disrupt shadows.
