Surface Preparation

---

Recommended Substrate Conditions and Temperatures

Substrate conditions

• Previous coat must be dry and free from any contamination
• Old existing sound coating; sufficiently roughened, dry and cleaned

 

Substrate Temperature & Application Conditions

---

• Substrate temperature during application should be above 5°C (41°F)
• Substrate temperature during application should be at least 3°C (5°F) above dew point

 

Application

---

Instructions for Use

• Stir well before use
• The temperature of the paint should preferably be above 15°C (59°F), otherwise extra thinner may be required to obtain application viscosity
• Adding too much thinner results in reduced sag resistance
• Adequate ventilation must be maintained during application and curing (please refer to INFORMATION SHEETS 1433 and 1434)

Safety Precautions

---

• For paint and recommended thinners, see information sheets information sheet 1430, information sheet 1431 and the relevant Material Safety Data Sheets in the attachments section above
• This is a solvent-borne paint and care should be taken to avoid inhalation of spray mist or vapour, as well as contact between the wet paint and exposed skin or eyes
