How to apply Liquid Rubber?

Make sure that the surface is as clean as possible. Wipe with mentholated spirits.
Brush or roller the surface with Liquid Rubber using textile bandage to detail any joins, corners, penetrations etc.
Once the first coat is cured (approx. 24 hours), apply second coat allowing to cure. (For ponds etc. apply 3 coats!)

Video - Waterproofing with Liquid Rubber

This is a short video showing the many uses of Liquid Rubber. Liquid Rubber is 100% environmentally friendly containing no VOC's and is perfectly safe to use in the DIY environment.

Before application Liquid Rubber has a thin, paint like consistency but once applied it will dry into a seamless rubber membrane.
Minimal preparation and no primers needed.
Often there is no need to remove the current surface, saving on skip-hire, dumping fees or specialist labour.
Simply make sure you have the surface as clean and as dry as possible
For seams, joins or holes a re-enforcement cloth (bandage) is applied on top of a first coat and then secondary coat applied over the cloth (similar process to fiber-glassing).
Overall two coats of Liquid Rubber is required in most DIY waterproofing
Ponds and such continuously withholding water you should apply at least 3 coats allowing to cure for at least 3 weeks before taking into use.

DIY Waterproofing -
Preparation Guide

We have over 30+ years of construction and waterproofing experience and use Liquid Rubber for our own projects.

When doing a DIY application the ONLY way it can "go wrong" is when the steps are not carried out properly and a shortcut has been taken or lack of care when preparing or applying.

Stir Liquid Rubber well before application.
Stirring can be done with clean stick, paint stirrer or a slow speed drill with helical mixer.
Liquid Rubber application does not require special equipment and is perfect for all those small domestic projects.
It is easily applied using a paint brush or roller.
2 THIN coats are recommended & 3 coats for all projects holding water permanently i.e tanks, ponds etc.
Product coverage will greatly vary depending on the surface and coat thickness.
Always install protection sheet over finished membrane when back filling or landscaping is required.
Being eco-friendly Liquid Rubber is safe for animals, plants & human drinking water (i.e water tanks, ponds).

Coverage: 15L Bucket approx. 11-13m2 @ 2 coats

4L Bucket approx. 3-4m2 @ 2 coats

Curing Time: Typically cures within 24-48 hours (depending on application thickness, temeprature and relative humidity) into a tough flexible waterproof barrier when applied to a minimum of 1000 micron (1mm) Dry Film Thickness (DFT)

Surface Preparation

As with all waterproofing membranes, the surface must be dry and free of anything that could adversely affect adhesion - if you apply the product correctly it WILL do the job.

You should be sure to remove all loose, scaling, peeling, blistering, chipping, cracking, chalking or gravel, dust, dirt, sand, soot, grease, oil, uncured tar, wax, soap film, animal fats or petroleum-based residue, coal, chlorine, salts, efflorescence or any other chemically reactive substance (solvents) that may affect adhesion.
Wire brush or if needed high-pressure water blast should be used to thoroughly clean all surfaces prior to application if any of the above conditions exist.
Surface should be free of all mold, mildew or any other living organism and COMPLETELY DRY.
Smooth surfaces such as glass, st-steel, plastics etc. should be abraded or etched beforehand. In some cases a primer may be needed.
If joins, corners, upturns and downturns or gaps need pre-filling, the sealant (usually polyurethane or acrylic) must be completely cured first or the gases from the sealant curing may cause harm to the membrane. *NOTE:
If using sealants in the joints and junctions etc. make sure the product is non-solvent based or non-acetic. We recommend using an acrylic sealant and allowing it to dry completely.
If using polyurethane sealant they must be allowed to completely cured before applying Liquid Rubber as the solvents in some polyurethanes will affect the Liquid Rubber (some even after they’re cured).

Curing Times

Typically cures within 24-48 hours (depending on application thickness, temperature and relative humidity).
You will notice the product is touch dry within 2-3 hours, however the Liquid Rubber is still going through a very important process called "curing" which may take one to several days to complete.
Curing is the process where the rubber becomes a single flexible membrane. Once Liquid Rubber can contain water on a continuous basis. This process can take between 5-7 days in warm weather or longer if moisture is held within.
If the substrate becomes damp from behind the membrane (i.e underground concrete, ponds surrounded by damp soil) this will greatly extend the curing process. DO NOT fill a pond, water feature, tank etc until the curing process is completed.
Blistering can occur if (water) vapor is trapped in substrate (more so when sun or heat is applied and creates water vapor- trying to "get out") Allow blisters to dissipate over time- repair if holes occur or cut out blisters - allow to dry out and re-apply Liquid Rubber over the patched area.
After the membrane has thoroughly cured, inspect for cracks & out gassing holes (blisters) or any surface irregularities that may need to be repaired. To effect any repair- Geotextile Bandage is used.

Cleaning After Application

While the product is wet it can be washed off in cold water (does not harm the environment).
After Liquid Rubber dries (cures) you will need to (safely) use Mineral turpentine or as more often used water base engine degreaser which washes off under water.
Coconut and baby oil will remove dry product (if you get any on your face etc.)
Most projects can be undertaken by a home handy person or tradie such as: caravan - camper roofs and undercarriages, boat decks & hulls, aquariums, fish ponds, planter boxes, balcony refurbishment, leaking roof/gutters, retaining walls etc. are

Liquid Rubber -
Product Safety/Storage

Liquid Rubber is a non-flammable liquid and does not present any storage or transportation hazards.
Store all Liquid Rubber in a cool dry space over 5°C - DO NOT ALLOW PRODUCT TO FREEZE.
Unused Liquid Rubber will last over 6 months if BUCKET IS TIGHTLY SEALED WHEN NOT IN USE.
(Tip: Place a piece of cling wrap or plastic over the unused liquid membrane inside the bucket then seal it up - this will prolong the remaining material longer.)
