2K DTM Metal Cladding Paint Gloss 5L

Preparation

Proper preparation is the most important step for ensuring the long-term adhesion of this 2-part chemical coating.

Substrate Inspection: Ensure the cladding is sound. Any previous coatings that are peeling or failing must be completely removed back to a firm edge.

De-greasing: Use an industrial degreaser to remove all traces of oil, bird droppings, or atmospheric pollution. For large areas of cladding, pressure washing with a cleaning solution is recommended, followed by a thorough rinse with clean water.

Corrosion Treatment: Any areas of active rust or “cut-edge corrosion” must be mechanically cleaned (wire brushed or sanded) back to bright metal.

Abrasion: Even though this is a “Direct to Metal” product, smooth or exceptionally shiny surfaces (like new galvanised metal or plastisol coatings) should be lightly abraded with a fine abrasive pad to provide a mechanical “key” for the paint to grip.

Drying: The surface must be 100% dry. Cladding often traps moisture in the overlaps and fixings; ensure these are completely dry before you begin painting.

Application

This product requires a chemical reaction between the base and activator to cure properly.

Initial Mixing: Stir the base paint on its own for 2 minutes using a mechanical drill stirrer to ensure all pigments and anti-corrosive additives are fully redistributed.

The 2-Part Mix: Pour the entire contents of the activator into the base tin. Mix again mechanically for 2–3 minutes until the liquid is completely homogenous.

Thinning: Only use T51 Thinners. Add 5–10% thinners after the base and activator have been mixed together. Do not use standard white spirit or cellulose thinners, as they will prevent the paint from curing.

Spray Setup:
* Airless Spray: Recommended for large cladding areas for a uniform finish. Ensure you maintain a consistent distance from the surface to avoid “dry spray” or runs.
* Conventional Spray: Adjust your pressure and thinning to achieve a smooth gloss flow.

Pot Life Management: Once mixed, you have a limited window to use the paint (typically around 4 hours at 20°C). Only mix what you can realistically apply in one session.

Environmental Check: Avoid application if the temperature is below 10°C or if there is a risk of rain or heavy dew before the paint reaches its “Dust Free” state (approx. 30 mins).

The Overcoating Window: If a second coat is required, apply it between 4 and 96 hours. If you wait longer than 96 hours, the first coat will have “hard cured” and must be lightly sanded before the second coat will bond to it.
