Product Information

Application Information

Waiting Time / Overcoating

Apply Sikalastic Metal Primer within 4 hours of blasting, before re-oxidation.

Before applying any recommended Decothane Roofing Systems; Sikalastic Roofing Systems & Sikalastic Balcony Systems - on Sikalastic Metal Primer, allow:

Note: Apply an additional coat if more than 7 days pass before coating. Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Application Instructions

Substrate Quality

Prior to the commencement of works, adhesion/substrate compatibility trials should be carried out onto the substrate to confirm substrate suitability and adhesion of the proposed system.

The surfaces must be clean, dry, free of stripping agents and free of oil, grease, silanes, salts, silicone, siloxanes and other chemicals which could cause poor adhesion.

Substrate Preparation

All surfaces to be coated should be thoroughly cleaned by conventional means.

Steel is ideally prepared by shot blasting to Sa 21/2 or SSPC 10 (nearly white metal). Where blasting is not permitted then clean metal preparation by power tools is acceptable.

Non-ferrous metals are prepared by removing deposits of dust and oxidation and abrade to white metal. Wire brushing can be used on soft metals, i.e. copper.

Ensure that surfaces are free from visible dampness and that all dust, loose and friable material is completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.

If in doubt apply a test area first.

For detailed information regarding substrate quality/preparation and primer chart please refer to Method Statement.

Application

Prepare Sikalastic Metal Primer by stirring component A until uniform, add component B and mix by electric drill until a homogeneous colour is achieved and the product is free of streaks.

Sikalastic Metal Primer can be applied by short-piled roller or brush.

Allow primer to dry sufficiently (see table Waiting Time / Overcoating) before overcoating.

Cleaning of Tools

Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.

Limitations

• Do not apply in wet weather or to wet surfaces
• Do not use Sikalastic Metal Primer for indoor applications
• Always ensure good ventilation when using Sikalastic Metal Primer in a confined space, to ensure drying and full curing
• Any surfaces left uncovered for a period of more than 7 days should be re-primed
