They effectively seal and protect against water damage, offer decorative options, can be non-slip, and are suitable for foot traffic, making them versatile and reliable choices for waterproofing applications.

How to Waterproof a Balcony or Deck

VersEseal Rapid Build, VerseGRIP and VersEseal TopGrip are water based however, gloves, eye protection and overalls are recommended. Please read the full Safety Data Sheet before

1. Remove any old, failed sealant with a scraper, if possible. If it can’t be removed, treat the area like a gap and reinforce with geofabric as below.

2. Wash down to remove all dirt, dust and grime. A pressure washer is ideal for this. Allow to dry.

3. Lightly abrade the surface to maximise adhesion, use a medium grit sand paper. Wipe with a damp cloth to remove sanding dust.

4. Apply masking tape to give a clean edge to areas that are not to be coated. PROTIP: Remove masking tape while the coating is still wet and re-mask for each coat.

5. Prepare Geofabric to reinforce along joins, around penetrations and over old sealant. It is much easier to pre-cut geofabric to size before starting to coat the membrane.

6. Brush the first coat of VersEseal Rapid Build or VerseGRIP liquid rubber over areas that need repair or additional reinforcement. Aim for a good thick coating. Remember, you’re waterproofing, not painting – thick is good!

7. Lay geofabric bandage into the wet coating over joins and around penetrations. Ensure it is smooth with no creases or air pockets. You may need to cut a nick to allow the bandage to neatly conform to any corners or bends. If the fabric overlaps, paint some VersEseal Rapid Build or VerseGRIP liquid rubber between the layers to glue it together.

8. Immediately brush a second coat of VersEseal Rapid Build or VerseGRIP liquid rubber aiming again for another good thick coating to give a wet on wet sandwich with a total wet coating thickness of 1mm.

9. Allow the repaired area to dry. This will typically take about 4 hours at 25℃ with good ventilation.

10. The final sealing step will depend on the condition of your deck.

  • ENTIRE DECK – Apply two generous coats of VersEseal Rapid Build or VerseGRIP liquid rubber over the entire deck to achieve a final Dry Film Thickness (DFT) of 0.6mm over the main deck area and 1.2mm over joints and repaired areas. Apply the first coat NorthSouth and the second coat East-West. Allow to dry for at least 4hrs between coats of VersEseal Rapid Build or VerseGRIP Membrane. After final coat of VersEseal Rapid Build or VerseGRIP Membrane, allow to dry for 96hrs before applying VersEseal TopGrip – assuming good drying conditions of 25℃ and good ventilation.
  • REPAIR ONLY –  If your deck is sound apart from the areas that have been repaired: Apply a third good thick coat of VersEseal Rapid Build or VerseGRIP liquid rubber over the repaired areas, to achieve a final Dry Film Thickness (DFT) of 1.2mm and allow to dry, allow to dry for 96hrs before applying VersEseal TopGrip – assuming good drying conditions of 25℃ and good ventilation.


11. Allow the VersEseal Rapid Build or VerseGRIP membrane to dry for a minimum of 96hrs in good drying conditions (25℃ with good ventilation / breeze). If conditions are not optimal a longer drying time will be required – actual times will vary depending on season and location. If you are unsure or would like further guidance on this please give us a call.

NOTE: VersEseal Rapid Build or VerseGRIP should be applied at a minimum total wet coating of 1kg/m2. Ensure this correct coating thickness is achieved to provide longevity.

12. Using a clean brush or roller, apply the first coat of VersEseal TopGrip over the VersEseal Rapid Build or VerseGRIP Waterproofing. This may show some bleed through from the black colour underneath. Allow to dry, typically this will take 2 hours at 25℃ with good ventilation.

13. Apply the second coat of VersEseal TopGrip and allow to dry. A third coat may be required depending on application technique to achieve full coverage.

14. The final product should have a DFT of 0.5mm of TopGrip on top of the VersEseal Rapid Build or VerseGRIP.

15. Allow VersEseal TopGrip to dry for 24 hours in good drying conditions (25C with good ventilation / breeze as described above)

NOTE: VersEseal TopGrip should be applied at a minimum total wet coating of 1kg/m2. Ensure this correct coating thickness is achieved to provide longevity.

Do not use this water based VOC Free coating system if rain or heavy dew are expected before fully dried. Apply at temperatures between 10℃ and 30℃. Avoid applying during the hottest part of the day.

For Cleaning up, use mineral turpentine to clean VersEseal Rapid Build or VerseGRIP from hard surfaces, use Baby Oil (Mineral oil) to clean from skin. Verseseal TopGrip can be cleaned with water.

For customised advice for your project, please give us a call on 1300 891 576 to discuss your particular needs.

VersEseal exhibits excellent adhesion, forming a strong bond with surfaces such as concrete, timber, cement board, Villa board, and tiles. This ensures a durable and reliable waterproofing barrier that withstands foot traffic and environmental conditions.

Yes, VersEseal can be applied directly over existing tiles (if coating over glazed tiles, please contact us for further advice).

This makes it a convenient and cost-effective solution for waterproofing tiled surfaces such as decks and balconies.

VersEseal is a trusted waterproofing product renowned for its ability to seal and protect various surfaces from water damage, including balconies. However, the effectiveness of VersEseal in addressing your specific balcony leakage issue depends on several factors. To ensure the best outcome, we recommend following these steps:

  • Assessment: It is crucial to evaluate the condition of your balcony and determine the source of the water leakage. We recommend seeking the assistance of a qualified contractor or waterproofing specialist to conduct a thorough inspection.
  • Professional Advice: Based on the inspection results, consult with experts who have experience in waterproofing and building maintenance. They can provide tailored recommendations and guide you through the appropriate solutions for your specific situation.
  • Comprehensive Approach: Resolving water leakage requires addressing the underlying cause. In addition to using VersEseal, other actions may be necessary, such as improving drainage systems, or addressing structural issues. It is essential to implement a comprehensive approach to prevent further damage.


By combining the versatility and reliability of VersEseal with professional expertise, you can significantly reduce the risk of water leakage and ensure a long-lasting, waterproof balcony.

Please note that this information is general in nature and intended as a guideline. For detailed advice and specific product recommendations, we encourage you to reach out to our knowledgeable customer support team or consult with local professionals familiar with your region’s building requirements.

Remember, VersEseal is designed to provide exceptional waterproofing performance, and we are confident that it can be a valuable part of your solution.

Yes, VersEseal can be used in new construction projects. Its versatility allows for application on various surfaces, making it suitable for waterproofing decks, balconies, and other areas. Additionally, the VersEseal Liquid Rubber membrane is approved to AS4654.1, meeting the standards for external UV exposure above ground membranes. This ensures that it provides reliable and durable waterproofing protection in new construction applications.

VersEseal should be applied to reach the required thickness rather than for a number of coats. For decks and balconies, a minimum of two coats is required to give a final Wet Film Thickness of 1mm at a minimum. This equates to 1kg per square meter. A thicker coating may be required depending on the substrate. Please contact us for specific advice for your project.

It is important not to use silicone or any other new gap filler or sealant before applying VersEseal. These products may contain slow-release solvents that can affect the performance of the VersEseal membrane. Instead, any gaps should be filled with VersEseal Rubber Caulk and bridged over using the Geo Fabric method. This ensures compatibility and optimal results with the VersEseal waterproofing system.

If you have old silicone or polyurethane sealants on your deck which are lifting and peeling, they will need to be removed to ensure you have a solid substrate to coat over. If small amounts of the sealant cannot be removed, treat it as if it’s a gap and bridge across it with Geo Fabric as shown in our application videos.

Our VersEseal Liquid Rubber membrane is only available in black. However, VersEseal TopGRIP is available in a wide range of colours including Colorbond roofing colours. We are happy to match custom colours for specific jobs subject to minimum order quantities.

VersEseal TopGrip has been specially developed to ensure it won’t damage the membrane like a solvent based paint would. It will also expand and contract with the membrane, so it won’t crack and peel like standard paint.

We manufacture all of our products in our Queensland factory. Experience has taught us it is much better to deal directly with our customers to give them the best advice for their individual project. Therefore, VersEseal products can only be purchased direct from us online, over the phone or in person. You can find our online shop here:
