Watco Protecta-Coat is a new type of resin formulation that can be applied in cold conditions, as low as minus 10°C, when conventional coatings will fail to dry.

Protecta-Coat uses the latest polyaspartic technology for an exceptionally durable protective coating. It is ideal for long term protection of epoxy and decorative floor finishes.

Protecta-Coat is extremely resistant to UV and has excellent resistance to weathering. This adds to it’s versatility since it can be used all year round for many different applications, as a clear, hard wearing coating in its own right, or as the ultimate protection for previously painted floors.

The tough, highly glossy coating is smooth and easy to keep clean and maintain.

Watco Protecta-Coat Anti Slip provides a good level of slip resistance.

Protecta-Coat and Protecta-Coat Anti Slip both carry CE Mark EN1504-2 and have impressive test results for abrasion resistance, as well as for adhesion and hardness.

• Fast curing – ready for heavy traffic in just 16 hours
• Superior abrasion and scratch resistance
• Extremely hard wearing
• Flexible – copes with slight movement around vibrating machinery
• Superior performance demonstrated by ISO testing to CE Mark EN1504-2

Surface Preparation

Painted surfaces – lightly abrade to remove any weak or loose paint and check remaining paint is well bonded. Do not worry about any minor scuff marks that appear as a result of light abrasion since they should disappear once the ProtectaCoat has cured. Watco Bio-D can be used to remove grease and oil from painted surfaces. Watco Concroff is a very powerful degreaser for contaminated bare concrete, which should not be used on a previously painted surface since it can soften paint

Application in low temperatures – If applying in cold conditions the product should ideally be stored in a warm room for at least 8 hours prior to use. Below 5°C it may be necessary to avoid processes which involve wetting the floor due to the difficulty in drying. A good sweep or mechanical brushing may be sufficient. All surfaces must be -10°C or above and free from ice or water.

Bare concrete – remove surface laitance, dust and any light dirt or grease deposits using Watco Etch & Clean. Watco Etch & Clean also etches smooth, bare concrete surfaces to provide a key. Flush with clean water and allow surface to dry. For the removal of heavier deposits of oil and grease we recommend Watco Concroff, again, flush with clean water and allow the surface to dry

New concrete – as a guide, new concrete should be left for eight weeks to dry. The surface should then be prepared using Watco Etch & Clean and thoroughly rinsed away and left to dry prior to applying this coating

Priming – is not usually required, but for open textured, or very porous high suction surfaces, such as sand and cement screed, use Watco Polyaspartic Primer to ensure a uniform finish and to prevent air entrapment bubbles. Smooth (but not power floated) concrete should also be primed with Watco Polyaspartic Primer to improve adhesion.

Metal – remove any rust or flaking material by disc grinding or wire brushing. Apply the coating immediately after preparation to the clean metal surface. Grease or oil can be removed using Watco Bio-D. Allow the metal to dry before coating.

Galvanised Metal – Watco Galvaprime must be used to prepare galvanised metal.

Non-ferrous Metals – for advice, please contact our Technical Department on 0113 2455450 (option 2) or send a message to [email protected]

Wood – must be sound, clean and dry. If applying the anti slip version to ridged decking, please ensure that the grit particles are spread evenly across the surface.

Mixing

Mix between 10°C and 25°C. Remove the inner tins from the tall outer tin. Stir the contents of the resin tin thoroughly, (scraping around the inside of the tin to remove any residue and pour into the outer tin), then do the same with the curing agent - if using the anti slip version add the tin of fine grit. Mix the components together thoroughly using a spatula or similar wide bladed tool, (a piece of wooden batten is ideal). Continue mixing until an even consistency is obtained. Do not mix more than one pack at a time. If a paint stirrer fitted to an electric drill is used, also use the spatula to blend in any unmixed material for the side and bottom of the tin. Do not dilute.

Application

Empty all of the mixed components into a shallow paint tray. Do not leave any in the tin. Apply to the floor using a short pile roller, (not a medium pile or foam), ‘working out’ the coating into a thin film to a measured area of 30m2 . A paint brush can be used for cutting in. Do not apply the coating too thickly since this will reduce the slip resistant properties and result in reduced coverage. If using the anti slip version, periodically agitate the mixed components in the shallow tray; this stops the grit from settling and re-disperses it ensuring a uniform finish is achieved.
