VersEseal is a highly versatile and effective sealing solution designed for various applications. It has excellent adhesive properties and sticks to a wide range of surfaces, including:

1. Concrete: VersEseal adheres well to concrete surfaces, making it suitable for sealing concrete roofs, water tanks, retaining walls, and other concrete structures.
2. Metal: It sticks firmly to metals such as steel, aluminium, and galvanized surfaces. This makes it ideal for sealing metal roofs, gutters, flashing, water tanks, silos, and other metal components.
3. Masonry: VersEseal adheres to masonry surfaces, including bricks, stones, and blocks. It can be used for sealing masonry walls, chimneys, and foundations.
4. Wood: It effectively sticks to wood surfaces, making it suitable for sealing wooden decks, fence posts, and other wood structures.
5. Bitumen: VersEseal adheres to bitumen surfaces commonly found in roads, pavements, flat roofs, and parking areas. It provides a reliable seal for such applications.
6. Fibreglass and Non-porous surfaces: Surfaces such as fibreglass, glass, plastics, and some types of tiles may require some additional preparation or application of VersEseal Non Porous Primer prior to coating.

Yes, VersEseal sealant is safe for both drinking water and use in confined spaces. It contains no Volatile Organic Compounds (V.O.C’s) making is suitable for use in confined spaces. It is also approved for portable water in line with Australian Standard AS4020 and is used in major water reservoirs around the country.

VersEseal should be allowed to dry thoroughly before applying any additional coats. The drying process typically takes 24-48 hours per millimetre at a temperature of 24 degrees Celsius in a well-ventilated area. If conditions are not optimal due to low temperatures, high humidity or no breeze, 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 don’t hesitate to get in contact.

Any areas of rust should be treated with a water based rust convertor prior to sealing.

The application of VersEseal should be based on achieving the desired thickness rather than focusing on the number of coats. In general, a minimum of two coats is typically necessary to achieve a final Wet Film Thickness of 1mm, which corresponds to 1kg per square meter. In specific cases like water tank repairs, we may recommend applying up to 2kg per square meter. For more detailed information and personalised advice regarding the recommended quantity for your project, please don’t hesitate to get in touch with us.

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 adversely affect the VersEseal membrane. Instead, any gaps should be filled using VersEseal Rubber Caulk and bridged over using the Geo Fabric method.

In cases where you have existing silicone or polyurethane sealants that are lifting and peeling, it is necessary to remove them in order to ensure a solid substrate for coating. If you encounter small amounts of sealant that cannot be entirely removed, treat them as if they are gaps and bridge across them using Geo Fabric, as demonstrated in our application videos.

Our VersEseal Liquid Rubber membrane is currently offered exclusively in black. However, we do provide VersEseal Top Coat in white and an extensive range of colours, including Colorbond roofing colours. We are also able to match custom colours for specific projects, subject to minimum order quantities. 

VersEseal Top Coat has been specifically formulated to safeguard the membrane from any potential damage that may be caused by solvent-based paints. Additionally, it possesses the ability to expand and contract along with the membrane, ensuring resistance against cracking and peeling, which is often observed with 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.

Preparation is the most important aspect of any waterproofing work. The surface needs to be clean, dry, and free of any particles, dust, and chemical residue. Any old loose, chalky, or flaky coatings or paint will need to be removed prior to installing. Where possible, pressure wash the surface and allow to dry. Anything that has not been removed by the pressure washer can be coated over. We can only stick to what is underneath so it is important to have a solid substrate to coat over.

When coating onto good quality concrete or timber no primer is required, coat VersEseal Rapid build directly onto the substrate. If you are installing the VersEseal Membrane over new concrete, allow 28 days for the concrete to fully dry and cure to prevent any issues from outgassing.

When coating porous substrates such as Fibre Cement Sheeting, Villaboard, Wet Area Plaster Board, Porous Concrete, Porous Block Work, Particle Board or Magnesium Oxide Board use VersEseal Porous Substrate Primer. Apply a generous coat of 200g/m2 and allow to dry. This will typically take 2hours at 25°C with good ventilation. For Very porous substrates a second coat is recommended.

When Coating onto Non Porous Substrates such as Glazed Tiles or Plastic use VersEseal Non Porous Substrate Primer. Apply at 100g/m2 and allow to dry. This will typically take 2hours at 25°C with good ventilation.

Any penetrations, cracks, gaps, joints, holes, expansion areas can be filled with VersEseal Rubber Caulk or coated directly over depending on the size of the gap. To coat over, they will need to have a coat of VersEseal Rapid Build painted, then a length of Geo Textile Fabric placed over the top, then another coat of VersEseal Rapid Build. This Should all be done at the one time creating a wet on wet sandwich with the geo textile in the middle.

VersEseal can be applied using a brush, roller, trowel, and some airless spray guns.

If your VersEseal is kept in a cool dry place out of direct sunlight your bucket of VersEseal could last up to a year. This will depend on the size of the bucket and the amount of product remaining.

One of the best things about VersEseal is that it will stick to just about anything, which is why you should avoid getting it on things that don’t need waterproofing! If you get VersEseal on your skin it is best to use an old rag and baby oil to remove. Massage your skin with the baby oil and wipe off with a rag, continue until the VersEseal has been completely removed. For surfaces, it’s a similar process, using petroleum or solvent type products. Contact us first prior to attempting to remove VersEseal.

VersEseal is not compatible with hydrocarbons, solvents, and petroleum products such as petrol, diesel and oil based products. If there is any likelihood of these types of materials regularly coming into contact with your VersEseal membrane it is likely to cause a problem. Please contact us for specific details relating to your particular application.

Yes, it’s extremely important for any waterproofing or sealing application. So much so, it is part of the Australian Standards for Internal and External waterproofing.

Geo fabric is a synthetic material made from polyester, polypropylene, or other similar materials. It is designed to have excellent strength, and durability. With the VersEseal system, geo fabric is used as a bridging material to cover and reinforce gaps or in areas that require additional support.

Geo fabric is an important part of the Verseseal Waterproofing System that adds strength and reinforcement. It is commonly used in areas where extra support is needed, such as penetrations in walls, roofs, or floors, in cracked surfaces, at expansion joints, and where floors meet walls. Its purpose is similar to steel reinforcement in a concrete slab.

When you combine geo fabric with the Verseseal Waterproofing System, it helps prevent the membrane from being pushed through any gaps or cracks in these areas. Just like steel makes concrete stronger and less likely to break under pressure, the geo fabric acts as a reinforcement for the membrane. It strengthens the system overall, making it more durable and resistant to forces that could otherwise cause damage.

Using Geo Fabric correctly is a crucial step in your project, and proper preparation is key. Here’s a step-by-step guide on how to use Geo Fabric effectively:

1. Preparation: Make sure the surface is clean and dry. You can use a pressure washer or vacuum to remove any particles. Allow the surface to dry completely.
2. First Coat: Apply a coat of VersEseal Rapid Build, approximately 0.5mm thick, to the surface. Apply it slightly wider than the width of the Geo Fabric you’ll be using.
3. Cut or Lay Out: Cut the Geo Fabric to the required length or lay it out over the area you’re working on. Ensure there are no folds or creases in the fabric. If working on corners or curves, you may need to cut some darts in the fabric to ensure it lies flat. Ensure that any overlapping areas of fabric are glued together using VersEseal prior to continuing.
4. Overlapping Geo Fabric: If you need additional lengths of Geo Fabric, overlap them properly. Place the first length of Geo Fabric over the wet VersEseal Rapid Build. Apply another coat of VersEseal Rapid Build (at least 50mm) over the area to be overlapped. Then, lay down the second length of Geo Fabric, making sure there is enough overlap.
5. Second Coat: Apply a second coat of VersEseal Rapid Build, approximately 0.5mm thick, to the area. Ensure the entire Geo Fabric is completely soaked.
6. Drying Time: Allow the applied coats to dry completely before adding any additional coats. The drying time is approximately 24-48 hours per millimetre at 24 degrees Celsius in a well-ventilated area.
7. Visual Inspection: Before applying additional coats, visually inspect the membrane. The colour should change from brown to black as it cures. You can also touch-test the membrane – cured areas will feel much harder compared to wet areas. If the membrane feels “spongy” underneath despite being cured on top, it is still wet.
