How does the SEMCO Liquid Membrane™️ differ from other waterproofing membranes?
Our SEMCO Liquid Membrane has much better adhesion, It has an elongation up to 1300% before break, others only has 800%. and It can be applied to almost all hard surfaces.

Why should I use SEMCO Liquid Membrane™️?
If you’re looking for a high-quality elastomeric waterproofing membrane, you’ve found a product that does it all! Our SEMCO Liquid Membrane has so many uses. You can use it in applications as a primary waterproofing on wooden substrates or cement board and apply tile over it. You can use it to seal your leaking roof, pond , swimming pool and preserve and protect your wood. Apart from all this, you can also bridge cracks that you have in your substrate.

What is the coverage of SEMCO Liquid Membrane™️?
The coverage of the SEMCO Liquid Membrane™️ is approx. 2-3m2 per litre at 3 coats (0.75mm each coat). Coverage may vary depending on porosity of the substrate. For corrugated metal please calculate at least 33% extra material.

What is the cost of SEMCO Liquid Membrane™️?
18.9L of SEMCO Liquid Membrane™️ costs $601 and has a coverage of 50-60m2 for 2 coats. Let's break it down to the low end of the coverage and it would work you out to only $12 per square meter.

Can tiles be applied on top of SEMCO Liquid Membrane™️?
Yes, absolutely! You can apply the SEMCO Liquid Membrane™️ on your substrate, apply the SEMCO Liquid Membrane™️ as a primary waterproofing and apply tile over it with your mortar/thin-set.

Can one paint over SEMCO Liquid Membrane™️?
Yes, absolutely! We recommend a urethane based or water based acrylic paint if you wish to paint over the SEMCO Liquid Membrane™️

Is SEMCO Liquid Membrane™️ safe to use with fish and vegetables?
Yes, Liquid Membrane is fish and plant produce safe. We are LEED certified and certifications of low VOC content which also makes it safe to apply in confined spaces.

How do I ensure the Liquid Membrane™️ has bonded to the surface I apply it to?
To ensure that the SEMCO Liquid Membrane has bonded to the substrate, we recommend doing a pull test. This is where you place a piece of tape anywhere on the membrane and pull it off. If the membrane does not come off, then that signifies that it has fully bonded.

Is SEMCO Liquid Membrane™️ water based and low VOC?
Yes, it is water-based and contains a VOC content of less than 14g/L.

What does SEMCO Liquid Membrane™️ feel like when dry?
This product dries hard with a semi-gloss finish.

Can the SEMCO Liquid Membrane™️ be used as a finished surface that I can walk on? 
If you're installing our Liquid Membrane as a finish coat, the membrane needs to be sealed using our SEMCO Titan Shield Gloss.

Before installing SEMCO Liquid Membrane™️, what surface preparation needs to take place?
Before installing, make sure you follow the installation procedures based on the surface you're applying our Liquid Membrane onto. You can find our surface preparation matrix by clicking here.

Can SEMCO Liquid Membrane™️ be used as self-levelling?
No, it can not be used as a self-levelling product.

Is SEMCO Liquid Membrane™️ slippery when wet?
Although it is not slippery, as it is a membrane the product does not have a slip resistance rating. If you’re using Liquid Membrane as a finished coat, more resistance can be added by adding ant-slip or quartz sand between coats prior to sealing.

Can SEMCO Liquid Membrane™️ be installed inside a pool?
Yes, you can apply our Liquid Membrane to concrete and fiberglass pools following our pool installation method. For fiberglass pools we recommend sanding it with 60 grit sand paper and using Prep B.

Can you use SEMCO Liquid Membrane™️ over tiles?
Yes, you can apply Liquid Membrane over tile. We recommend preparing your surface using PREP B (Power Cleaner and Stone Soap).

Can SEMCO Liquid Membrane™️ be used in a potable water application?
At this current moment, we can not recommend this product for potable (drinking) water applications. Since the Liquid Membrane is so versatile, it can also be used on the exterior side of the substrate.

Why does my SEMCO Liquid Membrane™️ discolour when getting in contact with water?
Product discoloration is a clear sign that the SEMCO Liquid Membrane™️ has not fully cured yet however it will not affect its waterproofing capabilities. It is important to stick within the recommended preparation, re-coating times and thickness per coat. Any deviation may cause an exponentially prolonged drying and curing times. If you have already filled up the pool/fountain with water, drain it and allow curing to happen. If in doubt reach out to customer service via call, email or live chat.

How do you apply the Fabric Reinforcement?
First apply a good coat of Liquid Membrane over the joints/seam. Then put the Reinforcement Fabric on to the freshly applied Liquid Membrane. Press it flat and then apply 5-10 minutes later another coat of Liquid Membrane over the Fabric to embed it. Once you re finished with all the joints/seams, wait 30-40 minutes and then apply 2 coats of Liquid Membrane over the entire surface that you want to waterproof.

Can I use SEMCO Liquid Membrane™️ for my driveway?
Yes, you can apply Liquid membrane as a waterproofing application and then apply 3 coats of SEMCO Titan Shield over for trafficable durability.
