No Primer needed! Sticks to all surfaces without Primer!

Flexible, and suitable for use on nearly any surface. Simply paint or spray on the sealant and watch as it instantly molds to whatever shape it's applied. The sealant then dries to create a flexible and seamless waterproofing barrier that's resistant to cracking and aging.

What colour is it?

The sealant initially appears dark brown but cures to a black finish.

Note: When Liquid Rubber Waterproof Sealant is immersed in water, it may appear slightly brown. Once fully dry, it turns to a deep black color.

Can it be painted over?
If you wish to paint over the sealant, apply one coat of our Primer / Sealer on top of the sealant first. This will ensure optimal adhesion and a smooth finish.

Frequently Asked Questions

format_paintApplication

Metal Roofs:

For general metal roof and rendered concrete coverage, apply 1.5L/m².

Keep in mind that the coverage will vary depending on the product used:

  • 15L Bucket covers: 10m²
  • 4L Bucket covers: 2.5m²
  • 1L Bucket covers: 0.6m²

Concrete Surface:

For rough or uneven concrete surfaces, apply a minimum of 2L/m².

On concrete roofs, It is recommended to first apply a 2 Part Epoxy to the surface before applying the rubber to prevent bubbling.

  • 15L Bucket covers: 7.5m²
  • 4L Bucket covers: 2m²
  • 1L Bucket covers: 0.5m²

1. Start by cleaning the surface to remove any dirt, oil, or impurities. If needed, use a water blaster or wire brush to remove stubborn debris or rust. Allow the surface to dry completely.

2. Fix areas with holes, cracks, or joint movement using Geo-Textile. Simply embed it into the Liquid Rubber Sealant over the affected areas.

2. Apply the Liquid Rubber to the surface using a brush, roller, or spray machine. Make sure to spread an even layer, each coat should be at least 2mm thick. Be sure to fully cover the surface, including protrusions, for complete coverage.

3. Allow the first coat to dry for at least 24 hours before applying the next coat. Repeat this step until you have achieved the desired thickness.

4. Allow the final coat of Liquid Rubber Sealant to dry completely for a minimum of 24 hours before applying any additional products such as Sealer or Thermal Coating.

5. Clean any excess or dried liquid rubber with mineral turpentine or WD40 before the Rubber Sealant Membrane is fully cured.

6. That's it, you have now successfully waterproofed your surface with Liquid Rubber!

Please Note:

  • It is best to apply the product early in the morning or in the afternoon during the summer months, to avoid the intense sun.
  • Remember to always apply Waterproof Sealant to the side of the project that will be in contact with water.
  • Make sure to avoid using solvents such as petrol, thinners, or diesel when using our water-based products.
  • To prevent bubbling and ensure proper curing, do not apply the Liquid Rubber Sealant if there is dew, cold wind, or rain forecasted within the next 24 hours. Also, ensure to prime all concrete surfaces with a high-quality 2-part epoxy before applying the Liquid Rubber
  • The curing time will depend on factors such as temperature, humidity, and airflow. The ideal curing temperature is 20°C or higher. Typically, the curing time is 3-7 days.
  • Do not apply in temperatures below 10°C or above 32°C.
  • To set the Rubber Sealant quickly, use Rapid Cure Spray (Optional). Note: Do not use a brush or roller on the wet Rapid Cure Spray, as it will cause the brush or roller to harden.

Liquid Rubber Waterproof Sealant can be applied to a wide range of surfaces

  • Metal roofs
  • Concrete roofs,
  • Box gutters
  • Tanks and Throughs
  • Water Tanks (Potable Water Certified)
  • Planter boxes
  • Retaining Walls
  • Sheds
  • Wooden or Metal decks
  • Ponds
  • and more....

Note:
The surface must be clean, dry, and free from contaminants for optimal adhesion.

For most applications, it is recommended to apply 2-3 coats for optimal waterproofing.

  • To use Liquid Rubber for waterproofing, the surface must be clean and dry. Remove any loose materials, dirt, grease, or other substances that could prevent the product from adhering properly.
  • If needed, use a wire brush or high-pressure water blasting to clean the surface.
  • Make sure the surface is free of mold or mildew and completely dry before applying the product. If the surface is smooth, such as glass or steel, it should be roughened up first.

There are several methods for effectively removing liquid rubber, depending on the type of surface it is on and the specific product used.

Here are a few options:

  • Solvents: Certain solvents, such as mineral turpentine or WD40, can dissolve Liquid Rubber and make it easy to wipe away. Be sure to test a small, inconspicuous area first to ensure that the solvent does not damage the surface.
  • Scraping: A putty knife or razor blade can be used to scrape away liquid rubber. This method is best for small areas or for removing rubber that has not fully cured.
  • Heat: Applying heat to Liquid Rubber can cause it to soften and become more pliable, making it easier to remove. A heat gun or hair dryer can be used for this method.
  • Mechanical tools: A wire brush or sandpaper can be used to mechanically remove the rubber. This method is best for rough surfaces.
  • Peel off mask: You can use a rubber masking liquid that can be peeled off after it has dried.
  • When the Liquid Rubber is still wet, it can be easily cleaned off with cold water.
  • Once it dries, or cures, you can remove it by using coconut or baby oil.

Yes, Liquid Rubber can be painted over. However, it's recommended to apply a Primer/Sealer before adding our Thermal Coating or any other type of paint. This ensures proper adhesion and provides a smooth, durable surface for the paint to bond to.

No, the surface must be dry before applying the sealant. Moisture can prevent proper adhesion and may cause the coating to fail.

Ensure the surface is thoroughly dry before application for the best results.

The drying time can vary depending on environmental conditions, such as temperature and humidity. \

Generally, it takes about 2 to 3 hours to be touch-dry and 24 to 48 hours to fully cure. Multiple coats may extend the curing time.

  • So, you can use it with peace of mind, knowing that it is safe for all.

Liquid Rubber is a great product that is safe to store and transport.

  • To keep it in the best condition possible, store it in a cool and dry place above 5°C and make sure it doesn't freeze.
  • When you're not using it, be sure to keep the container tightly sealed. This will help the unused Liquid Rubber last longer.
