Drying Times
Drying Times At 20°C | |
---|---|
Touch Dry: | 4 hours |
Hard Dry: | 24 hours |
- Allow hard dry prior to sanding
- HMG technical data sheets (see section above) indicate a dry film thickness that will be achieved when applying a particular wet film thickness
- These values are a guide only and are not to be used as specifications
- Film thickness will vary depending on actual use and specification
- Great care should be taken to achieve the dft stated in the agreed specification and to avoid areas of excessively low or high thickness
Surface Preparation
- Ensure surfaces are clean, dry and free from grease, oils, dust and other contamination prior to application
- Read and follow the safety data sheet, product data sheet (see section above) and label instructions
- Thoroughly clean and degrease using suitable HMG Prep Clean 2802, 2803 or 2804
- Rust/corrosion to be removed to Sa or St standards, remove to clean metallic appearance with little or no
rust/corrosion present - Areas where blast cleaning is not cost effective or practical, then the use of HMG Ferrozinc Rust Converter is an alternative
- Though HMG Ferrozinc is not an equivalent alternative to shot blasting, it does offer a far superior performance than conventional coatings applied to slightly rusted surfaces
- HMG Ferrozinc is used after simple wire brushing to remove surface rust, prior to application of primer
- Stir all paints thoroughly before use
- Always use the same batch number on the same job
- Check colour & sheen
- Filter the product immediately before use
- Reduce emissions and maintain quality by replacing tin lid after use.

- Adequate dry air ventilation should be supplied during drying
Application Information
- Thinning should only take place after material is thoroughly mixed
- Application and use should always conform with the codes of practice described in BS 6150 and BS 5493
Bare substrates
