Do Thin-Film Waterproofing Coatings Need Special Mixing?

Q: Two-component coatings that need measured mixing

Prolux and Icrystal are two-component systems, so the resin and hardener need to be combined before use. Prolux is mixed in a 2:1 ratio, and Icrystal also carries a 2:1 mixing ratio. Use clean measuring containers and mix slowly to avoid trapping air in the resin. This step is not optional. The hardener starts the chemical reaction that turns the liquid components into a solid, durable film, so the specified ratio should be followed as closely as possible.

Mixing requirements for thin-film waterproofing coatings depend on the resin system. Two-component coatings such as Prolux and Icrystal must be mixed in a specified ratio before application, typically using a clean container and a slow, thorough stir. One-component products like Resinstone do not require a separate hardener and are supplied ready to use, though you should always check the container for any preparation notes. Checking the product label and technical data sheet is the most reliable way to confirm the correct mixing method for each coating.

Whether you are sealing a concrete driveway or finishing a tabletop, the preparation step looks slightly different across the range. The key is knowing which system you have in front of you before you start, so the coating cures evenly and delivers the expected waterproof layer.

One-component options with no separate hardener

Resinstone is a one-component methacrylic resin, so it does not need a separate hardener or ratio measurement. It is supplied ready to apply for sealing concrete floors and driveways. If the product has settled in storage, a gentle stir may be recommended, but there is no two-part mixing step.

This can be a practical option if you want a simpler application process or prefer to avoid measuring resin and hardener.

When accurate mixing matters

Accurate mixing matters most when the coating will need to withstand foot or vehicle traffic, moisture or regular cleaning. A two-component product that has not been combined properly may cure unevenly or leave an inconsistent surface finish, so taking an extra minute to measure correctly is worthwhile.

Before you begin, confirm whether the product is one- or two-component, use clean tools, and follow the coverage and working time notes on the label.

Check the ratio printed on the container or technical data sheet.
Mix only the amount you can apply within the product’s working time.
Use clean, dry containers and stirring tools.
Apply in thin, even passes to suit a thin-film waterproofing layer.
