Remarkable Rhicryl – the benefits of concrete sealing

Concrete sealers serve as a barrier between concrete surfaces, such as concrete floors and driveways, and outside factors such as grease, dirt and chemicals. Although concrete is hard-wearing, it should be sealed to maintain quality, and prevent stains and water retention. Rhicryl provides a durable film for outstanding protection of stamped, stencilled, coloured and plain concrete surfaces. We outline the benefits of Rhicryl concrete sealer.

What is the importance of sealing concrete?

Unsealed concrete can result in weather disintegration, delamination and chemical damage.

Weather disintegration

Weather disintegration happens when there is a constant change in weather conditions and temperature.


Delamination is the splitting of layers on a surface, also known as blisters. The concrete will have small bubbles on the surface, caused by continuous exposure to direct sunlight.

Chemical damage

The air contains carbon dioxide, and concrete has calcium hydroxide. Through a chemical reaction called carbonatation, the two chemicals will form calcium carbonate. Calcium Carbonate reduces the durability of the concrete, and it will also affect the reinforcement steel within the concrete.

Why is Rhicryl the best concrete sealer?

Rhicryl is a hard wearing, durable and waterproof concrete sealer used for the protection of concrete substrates in vehicular and pedestrian traffic areas. It also offers chemical resistance and superior UV (non-yellowing) protection.

Other benefits of Rhicryl concrete sealer:

  • Fast drying – at 25C, Rhicryl is touch dry in 30 minutes and hard dry in 4-6 hours with recoating recommended after 4-6 hours. Pedestrian traffic is possible after 4-6 hours and vehicular traffic in 5-7 days.
  • Non-yellowing / UV resistant film
  • Controls dusting and ingress of dirt and grime into concrete substrate
  • Ease of application
  • Excellent weather resistance
  • Good water and abrasion resistance
  • Superior chemical resistance (mineral fats and oils, dilute alkalis)

What colours and sizes are available in Rhicryl concrete sealer?

Rhicryl comes in a range of colours in low to full gloss. Colour availability may be subject to a minimum order requirement. Rhicryl is available at Wagon Paints in 4L, 10L and 20L pack sizes.
