• Use a self-priming bituminous coating that bonds directly to surfaces without a separate primer

• Apply a cost-effective waterproofing solution with excellent coverage (approx. 12 m² per litre)

• Use a fast-drying coating (touch dry 4 hours, recoat after 12 hours) for quick project completion

• Apply a flexible coating that accommodates natural movement of timber and metal without cracking or peeling

• Use professional-grade waterproof protection from Teamac (100+ years of British coating expertise)

Coverage: Approx. 12 m² per litre @ 40 µm dry film thickness

Per Tin Coverage:
• 1 litre: Covers approx. 12 m² per coat
• 2.5 litres: Covers approx. 30 m² per coat
• 5 litres: Covers approx. 60 m² per coat

Coverage varies depending on surface porosity and condition. Rough, porous, or heavily textured surfaces will absorb more product and require more per coat.

Example Calculations (two coats recommended for maximum waterproofing):

Small Project (fence posts & planter — approx. 5 m²):
• Coverage needed: 10 m² (two coats)
• Product required: Approx. 1 litre
• Recommended: One 1 L tin

Medium Project (guttering, downpipes & outbuilding base — approx. 15 m²):
• Coverage needed: 30 m² (two coats)
• Product required: Approx. 2.5 litres
• Recommended: One 2.5 L tin

Large Project (farm building, roof, or large fence run — approx. 30 m²):
• Coverage needed: 60 m² (two coats)
• Product required: Approx. 5 litres
• Recommended: One 5 L tin

Very Large Project (approx. 60 m²):
• Coverage needed: 120 m² (two coats)
• Product required: Approx. 10 litres
• Recommended: Two 5 L tins

For accurate project planning, measure your total surface area and allow for two coats minimum. Order 10% extra for surface variation and porosity.

Important: Touch dry 4 hours. Recoat after minimum 12 hours. Do not overcoat with conventional solvent-based paints — black bitumen will bleed through.

Recommended System Products:
• Paint Brushes • Paint Rollers • Roller Trays & Accessories

Metalastic is suitable for wood, ferrous metal, asphalt, and concrete. Ideal for fence posts, raised planters, guttering, downpipes, water tanks, farm buildings, outbuildings, roofs, and any surface requiring flexible waterproof protection.

Can I overcoat Metalastic with another paint?

This is the most important thing to understand about Metalastic. Do not overcoat with conventional solvent-based paints — black bitumen will bleed through any conventional paint system applied on top. Metalastic is a permanent black finish. Water-based paints may be applied over fully cured Metalastic with caution — always test on a small area first before full application.

Is Metalastic self-priming?

Yes — Metalastic is self-priming and bonds directly to prepared wood, metal, asphalt, and concrete without a separate primer. This saves time and money on primer costs.

How do I apply Metalastic?

Apply by brush or roller — no thinning required, apply neat straight from the tin. Stir thoroughly before use. Apply evenly, avoiding pooling or overly thick coats. Allow minimum 12 hours between coats. Clean equipment immediately after use with Thinners 14.

Touch dry in 4 hours, hard dry in 12 hours at 20°C. Recoat after minimum 12 hours (overnight). Drying times may be extended in cooler temperatures or high humidity.

How many coats do I need?

Two coats are recommended for maximum waterproofing protection. Allow minimum 12 hours between coats.

What coverage can I expect from Metalastic?

A 1 litre tin covers approximately 12 m², a 2.5 litre tin covers approximately 30 m², and a 5 litre tin covers approximately 60 m² per coat. Coverage varies depending on surface porosity — rough or porous surfaces will absorb more product.

Can I use Metalastic on raised garden planters?

Yes — Metalastic is ideal for protecting raised garden planters and timber sleepers from moisture and rot. Apply two coats to all timber surfaces that will be in contact with soil or water. The flexible waterproof film protects timber from moisture penetration and extends the life of planters significantly.

Can I use Metalastic on guttering and downpipes?

Yes — Metalastic is suitable for guttering, downpipes, and metal drainage systems. Apply to clean, rust-free metal surfaces. The flexible bituminous film provides excellent waterproof protection and rust prevention.

Is Metalastic suitable for water tanks and reservoirs?

Yes — Metalastic is suitable for water tanks and concrete reservoirs. Apply two coats for maximum waterproofing. Allow full cure before introducing water contact.

What temperature do I need to apply Metalastic?
