ALKA Coatings PRO-SEAL Polyaspartic 10L kit

Low VOC top coat with low viscosity

$550.00 inc GST




Alka Pro Seal is a two component, clear, ultra-high solid Polyaspartic topcoat.

Alka Pro-Seal is low VOC top coat with low viscosity allowing film thickness to build in excess of standard systems with water clarity and mirror-like smoothness and gloss.

Alka Pro-Seal can be used as a top-coat for interior and exterior decorative finishes such as flake floorings and epoxy partial flakes systems. Also, as a clear topcoat for all epoxy self-levelling and epoxy coating systems. As a clear self-levelling resinous flooring it can be used on exposed aggregates and polished concretes.

  • Short waiting times before subsequent coatings



Alka Pro-Seal Before the application, make sure that the substrate is free from dust, surface water and surface contaminants such as oil, grease, fats, chemicals, rust, paints curing membranes, etc. All loose materials and surface laitance must be removed. For larger areas shot blasting, high-pressure water blasting or scabbling is recommended. On small areas needle gunning or bush hammering can be effective. Please bear in mind that the tensile strength of the substrate must be a minimum of 1.5MPa. Pre-wetting the substrate is not necessary except on very absorbent substrates and/or when exposure to intense sunlight is probable. There should be no visible or standing water.

Shake component A shortly and pour Component B into Component A. Mix with an electric stirrer for at least 3 minutes.

Alka Pro-Seal is a versatile product and can be applied by brush, roller, squeegee or spray.

NOTE: Alka Pro-Seal and all polyurethanes and polyaspartic products have their own special solvent and normal Xylene must not be used as a thinner.

After application and for the cleaning process, Xylene can be used for cleaning tools and equipment before the mixed compound begins to harden. Once cured, it must be removed mechanically.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
