APPLICATION TIPS
PROFESSIONAL APPLICATION GUIDE
Following these guidelines will ensure the best results with Regent Paints products. Based on decades of roof coating experience, these recommendations maximise performance and longevity in Australian conditions.
BEFORE YOU START
Inspect the roof
Before starting, inspect the roof thoroughly. Replace broken tiles and ridge caps with matching second-hand tiles. Repair damaged flashings, valleys and gutters.
Check the existing coating
Test for solvent-based coatings by rubbing with mineral turpentine in an inconspicuous area:
- If it removes colour, it’s solvent-based and incompatible with our water-based products
- If it becomes sticky without removing colour, it’s acrylic and compatible
Clean thoroughly for proper adhesion
- Use a 3500+ PSI pressure washer with a turbo head
- Remove all dirt, moss, lichen and loose paint
- Pay attention to tile overlaps where dirt accumulates
- Allow to dry completely before coating
GETTING THE MIX RIGHT
Select the right products
For cement tiles:
- If tiles retain colour (showing signs of powdering): Use Tileguard® Maxi Prime
- If tiles have no colour left (moderately porous): Use Tileguard® Sealer
- If tiles are very rough and porous: Use Tileguard® High Build Sealer
For metal roofs:
- Clean thoroughly and ensure no rust is present
- Apply Tileguard® Maxi Prime and allow 24 hours to key to the surface
Calculate the quantity needed
Estimate the required product using:
- House squares × 10 × 1.3 × 2 ÷ 85 = Number of 20L pails
Example: A 25 square house needs approximately 8 drums of topcoat
Coverage rates:
- Topcoat: 85m²/20L (good tiles), 70-80m²/20L (poor tiles)
- Maxi Prime: 105-110m²/20L
PROPER TECHNIQUES
Weather conditions
- Apply between 14°C and 32°C air temperature
- Surface temperature should be 10°C and 45°C
- Avoid rain within 4 hours of application
- Remember: If it’s too hot to touch, it’s too hot to paint!
Application methods
- Ensure complete coverage with primers and sealers
- For metal roofs, apply Maxi Prime from peak to gutter in continuous streams
- Allow proper drying between coats (2 hours, 24 hours for Maxi Prime on metal)
- Apply two colour coats for maximum durability
- Never substitute one thick coat for two thin coats
System approach
Always follow the complete system for best results:
- Thorough preparation and cleaning
- An appropriate primer or sealer for the surface
- Two coats of colour (Tileguard, Regent Ultra or Heatguard)
FINISHING TOUCHES
Cleanup
- Clean equipment with water immediately after use
- Protect freshly painted surfaces from rain, dew or frost for at least 4 hours
Drinking water collection
- For roofs used to collect drinking water, disconnect downpipes for two good rainfalls before reconnecting
