Estimating Sealer Coverage

Coverage depends on surface texture and age.

Always follow the product data sheet.

How to estimate quantity

1. Measure the area in square metres (length × width).
2. Choose coverage rate from the table above according to surface condition.
3. Multiply area × coverage × number of coats.
4. Add 5–10 % for waste and edges.

Example

A 1,000 m² car park with average aged asphalt, two coats at 0.35 L/m²:

1,000 × 0.35 × 2 = 700 L, plus 10 % = about 770 L.

Factors that increase consumption

• Very porous or rough surfaces
• Hot, dry weather causing faster absorption
• Spray application with overspray

Always check the specific product data sheet and test a small area first.
