What Are Waterproof Coatings?

A waterproof coating is a liquid that is painted or sprayed onto a surface.
When it dries, it forms a solid, waterproof barrier.
Used on roofs, walls, floors, balconies, and many other surfaces.
Different types of coatings are used for different situations.
They stop water from getting through - protecting the structure underneath.
Most coatings also protect against UV rays from the sun.
A good coating can last 5–15 years depending on the product and conditions.

Types of Waterproof Coatings

Acrylic Coatings

•Acrylic is a water-based coating - easy to apply and quick to dry.
•Very flexible - it stretches slightly without cracking.
•Good UV resistance - does not fade quickly in the sun.
•Available in many colours - often used on roofs and walls.
•Breathable - allows moisture vapour out while keeping liquid water out.
•Best for: tile roofs, exterior walls, and surfaces in moderate climates.
•Usually needs to be re-applied every 5–8 years.
•One of the most affordable waterproof coating options.

Bitumen Coatings

•Bitumen is a thick, black, tar-like material - very tough and waterproof.
•Applied as a liquid or in sheet form (torch-on).
•Excellent for flat roofs, gutters, foundations, and below-ground surfaces.
•Not affected by water at all - used in very wet conditions.
•Can be painted over with a UV-resistant coating to prevent sun damage.
•Long-lasting - bitumen coatings can last 10–20 years.
•Not flexible on its own - may crack in areas with a lot of movement.
•Modified bitumen (with rubber additives) is more flexible and popular.

Polyurethane Coatings

•Polyurethane (PU) is the most flexible and durable waterproof coating available.
•It stretches significantly - can handle a lot of movement without cracking.
•Excellent for roofs, balconies, podium decks, and wet areas.
•Very resistant to foot traffic - used on walkable surfaces.
•Outstanding UV resistance - does not break down in the sun.
•Can be applied in one or two coats - dries to a tough, rubbery finish.
•More expensive than acrylic - but lasts longer and performs better.
•Best choice for flat roofs, exposed decks, and high-movement areas.

How to Choose the Right Coating

Tile roof: acrylic coating is usually best.
Flat roof with little movement: bitumen or acrylic.
Flat roof that gets very hot or has cracks: polyurethane.
Balcony or walkable surface: polyurethane only.
Below ground (foundations, basements): bitumen-based.
Gutters: bitumen or specialist gutter paint.
Walls: breathable acrylic or specialist masonry waterproofer.
Always ask your contractor which coating is best for your specific situation.

How Much Do Waterproof Coatings Cost?

Acrylic roof coating: R25 – R60 per m².
Bitumen coating: R40 – R90 per m².
Polyurethane coating: R80 – R180 per m².
Prices include labour and materials.
Surface preparation (cleaning, crack filling) adds to the cost.
