Preparation & Application


Recommended Substrate Conditions & Temperatures


Steel

  • Steel; blast cleaned to ISO Sa2½, SSCP-SP10
  • This primer should not be used where there is a risk of contaminant above pH 9

Concrete

  • Dried for at least 28 days in good ventilation conditions
  • Moisture content should not exceed 4.5%
  • Concrete must be sound, dry, free from laitance and any contamination
  • Rough surface; eventually abraded by power tool or diamond abrading tool

Substrate temperature and application conditions


  • Substrate temperature during application and curing should be above 10°C (50°F)
  • Substrate temperature during application and curing should be at least 3°C (5°F) above dew point
  • Relative humidity during application and curing should not exceed 85%

 

Instructions For Use


Mixing ratio by volume: base to catalyst 98:2

  • The reaction between the base component and catalyst is highly exothermic, deviation from the recommended mixing ratio should not be undertaken.
  • Pre-mix base component with a pneumatic air mixer at moderate speeds to homogenize the container
  • Add the catalyst while stirring the base
  • Mix thoroughly before application

 

Application


  • Never add any solvent
  • Never add the catalyst without continuous stirring

 

Airless spray


  • Airless pump 30:1 or greater, fit leather or FPTE seals and remove fluid filters, 10 mm diameter (0.375 in) nylon-lined hoses
  • Typical tip size is 0.46 – 0.74 mm (0.018 – 0.029 in) with reverse clean and 45° fan pattern
  • The size of tip and fan pattern will vary with the nature of the work
  • Use pressure to suit hose lengths and working conditions (circa 200 bar)

 

Brush/roller


  • For small areas only (touch up and repair)

Note: Surface should be flash blasted to provide physical key

 

Cleaning solvent


  • THINNER 50-02



Additional Data


Overcoating interval for DFT up to 120 µm (4.7 mils)
Overcoating with... Interval 10°C (50°F) 20°C (68°F) 30°C (86°F) 40°C (104°F)
NOVAGUARD 4801 Minimum 3 hours 1.5 hours 1 hour less than 1 hour
Maximum 4 days 3 days 36 hours 24 hours

Notes:

  • The maximum recoating time will reduce significantly at high temperature or in strong sunlight
  • Once the maximum recoating time has been reached, adhesion values attained by an subsequent coat will reduce dramatically
  • When this occurs, overcoating should be treated as repair with the coating flash blasted to provide a physical key
  • Styrene cannot be used to reactivate the surface of this product and may impair adhesion
  • Take care to avoid contamination before application or subsequent coat

 

Curing time for DFT up to 120 µm (4.7 mils)
Substrate temperature Dry to handle
10°C (50°F) 12 hours
20°C (68°F) 8 hours
30°C (86°F) 6 hours
40°C (86°F) 3 hours

Notes:

  • Full cure times are irrelevant for this product as it is purely a holding primer
  • Adequate ventilation must be maintained during application and curing

 

Pot Life


  • 1 hour at 20°C (68°F)

Note: The pot life will vary substantially with temperature



Safety Precautions


  • Since improper use and handling can be hazardous to health and cause of fire or explosion, safety precautions included with Product Data/Application Instruction and Material Safety Data Sheet must be observed during all storage, handling, use and drying periods
  • The catalyst of this product is supplied in small polythene bottles separately from the pigmented base component
  • It is a highly reactive, combustible and thermally unstable substance that can undergo self-accelerating decomposition
  • It is also a powerful oxidizing agent and will react violently with other organic chemicals
  • It is thus recommended to keep in original containers, to hold within the predetermined temperature limits, to prevent contact/contamination with other materials, and to minimize the quantity at the workplace – only have enough present for the job in hand
  • The waste of this product should be treated with special care; please contact the manufacturer (PPG) for more details

 

It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method.
