Testimonials
‘We had a leaking buytnol roof that we needed fixing asap. We called Liquid Rubber liking the idea of not removing the substrate. They came in, cleaned the roof, patched all the joins then sprayed out the roof before adding a UV topcoat. They were in and out very quickly and best of all, no more leaks.’
'We purchased the PAR product to repair our driveway. We had 3-4 large potholes which made the driveway not only look horrible but terrible to drive up. We were very amazed how easy the product was to apply. As it was a shared driveway we wanted to drive on it straight away, so we sprinkled sand over the PAR and it worked a treat. We now have a nice smooth driveway for hardly any cost.'
'We had a couple of trip hazards in our factory that we needed to get fixed. We wanted a strong product that we could walk/drive over ASAP. We used the MG Krete and we were amazed how quickly it set off. We could literally jump up and down over the concrete within minutes and had the forklift driving over it 30 minutes later. Very easy to work with and very minimal downtime.'
'We have used Cohe Group's products on multiple jobs and we love them all. They are quick and easy to use and most of all, there is minimal downtime which is crucial on our building sites. We have found the MG-KRETE’s cure time and strength second to none and the Liquid Rubber is so adaptable and easy to work with. The ease of PAR and the fact it can be applied in all weather conditions gives the guys work on rainy days.'
Liquid Rubber FAQs

Your surface must be clean and dry before applying Liquid Rubber products. It must be free from dust, dirt, oils, varnishes, surface flaking, poorly bonded or glossy paint, sealers, salts or any other substance, which will create a barrier and disrupt Liquid Rubber from adhering properly. Liquid Rubber can then be directly applied just like a paint using a brush, roller or spray gun.
Liquid Rubber can be applied with any normal paint brush or roller. You can also apply our Waterproof Sealant and Smooth Topcoat (but not our Textured Topoat) with a hydraulic piston sprayer. We hire out Spray Machines which can be found on our Shop section.
Liquid Rubber can be applied to virtually anything that is not oil based including concrete, wood, brick, masonary, most metals (iron, steel, galvanised steel, aluminium), butynol, shingles, tiles, difficult roof materials including EPDM, TPO, most PVC, SBS, APP, BURs, propylene, polystyrene, fiberglass and OSB. If you are unsure, please contact us to discuss your requirments.
Liquid Rubber products cannot be applied to silicon, certain smooth or shiny surfaces, e.g. plastic piping and varnishes or oil based paints.
A torch down membrane is a waterproofing membrane used on a flat or nearly flat roof. It is distinguished by seams or joins running parallel.
Liquid Rubber Waterproof sealant can be used to encapsulate the roof. You can’t water blast the roof however, we recommend spraying a moss/mould killer and leaving for one month before hosing off with light pressure from a garden hose. Then spray the liquid rubber over the roof before applying the smooth sealant for UV stability.
Please refer to our coverage guidelines on our product pages under DIY.
At 20°C Liquid Rubber takes 24 hours to fully dry. Please don’t try to peel it off the substrate for 3-4 weeks.
Remove any surface ponding and let it cure before applying another coat over the smooth coating. Apply Waterproof sealant to any affected areas that may have peeled.
Degradation will vary depending on wear and tear of the surface, exposure to UV rays and other corrosive substances. We recommend reapplying when the product visually starts to look as though it is eroding or after ten years.
Yes you can. So long as the surface is clean it will bond to itself.
Although not ideal, you can use methylated spirits and rags to remove.
We have Product Information Sheets for our products which provide general information about each product and how to use it. This should be sufficient for the home DIYer. We also have Material Safety Data Sheets (MSDS) which provide more technical product information.
Our Liquid Rubber Waterproof Sealant only comes in black. Our Textured Topcoat and Smooth Topcoat come in a range of standard colours. We can supply colours that are not in our standard range but there is a 20L minimum purchase.

As Liquid Rubber is safe for the user, no protective clothing is required from a safety perspective. However, as Liquid Rubber is difficult to remove from clothing we recommend wearing old clothing or overalls and gloves. This is purely for convenience and aesthetic reasons. Baby oil is useful for removing Liquid Rubber from skin.
Left over product can be stored in a cool dark place with the lid on. Keeping the paint brush in the product insde the pail (assuming it fits without sticking out) may avoid a skin forming on the top of the product. Left over product generally lasts 3-6 months.
Liquid Rubber is water based so can be removed from skin and brushes with any form of liquid soap and water before the product cures (dries). If Liquid Rubber has dried on your skin Baby Oil will help to remove it. Liquid Rubber does not come off clothing easily once it has cured.
No. However, if you are in an unventilated area, we do recommend a mask.
Liquid Rubber is water based, non-toxic, solvent free and contains no VOC’s (volatile organic compounds) so is environmentally safe.

Not ideally. The drier the substrate the better the adhesion will be.
