Get Started
What you'll need
- Equipment to prepare the surface
- Container to mix prime coat
- Paint brushes to apply the product
- Roller to embed the membrane
- Scissors to cut the membrane
- Gloves and old clothes
- super laykold® - 1 ℓ, 5 ℓ and 20 ℓ containers
- abe membrane – 200 or 250 mm wide
- bituprime or 4-metal primer – 1 ℓ, 5 ℓ, 25 ℓ containers
- silvakote® - 5 ℓ, 20 ℓ / silvakote® eco 5 ℓ, 25 ℓ
- abe® super brush cleaner - 1 ℓ, 5 ℓ and 25 ℓ containers
GOOD TO KNOW:
- Versatile system to suit any waterproofing application
- super laykold® is water-based, so dries fairly quickly. The wet material looks dark brown but dries black
- When used for a pond, allow to dry for a minimum of 14 days. Flush with clean water before filling completely. Let the water and product stand for a day or two before adding fish
Here's How: 5 Steps
Step 1
Surface Preparation
- All surfaces are to be clean, dry, sound, and free of all laitance, grease, oil, fungal growth, or loose and flaking particles.
- This could be achieved by wire brushing or high-pressure washing having a rotating nozzle and operating pressure of approximately 170 bar, finally rinsing with clean water
- New galvanised iron: The surface has to be thoroughly cleaned using sugar soap or any other grease-cutting detergent to remove oils followed by thorough rinsing or high-pressure washing using clean water to reveal a clean, sound, water-break-free surface
- Old galvanised iron: Remove all loose rust, dirt, and salts of zinc corrosion and scale by means of wire brushing, sanding, chipping, or mechanical scouring; down to bright metal followed by thorough rinsing or high-pressure washing using clean water to reveal a clean, sound, water break free surface
Step 2
Bonding
- Mix one part super laykold® with one part clean water and prime the total area to be covered. As a guide 0.25 ℓ of the diluted primer will cover 1 m². Allow to dry
- Metal surfaces only: New galvanised iron - prime with bituprime® or 4 metal primer and allow to dry. Old galvanised iron - prime with 4 metal primer and allow to dry
Step 3
Mixing
Stir well before use
Coverage:
- 2.1 ℓ /m² full system
Step 4
Application
First coat (all surfaces after priming):
- Brush or roll on a thick coat (0.75 ℓ/m2) and embed the abe® membrane well into the wet coating. On flat surfaces, it is recommended to use a fluted aluminium roller for this purpose
- Membrane overlaps should be a minimum of 100 mm on end laps and 75 mm on side laps
Second coat:
- When the first coat has dried sufficiently to take working traffic (2 – 3 hours), apply a second coat of super laykold® (0.75 ℓ/m²) to ensure the membrane is completely saturated, and allow to dry
Third coat:
- Apply a final coat of super laykold® (0.6 ℓ/m²) to give a smooth finish
Note: If super laykold® is used in a koi pond or dam, allow to dry for 14 days. Flush with clean water before filling.
Step 5
UV Protection
Allow the system to dry for 7 - 10 days and then overcoat exposed areas with silvakote®
Cleanup
- Tools, brushes and mixing equipment should be cleaned immediately after use and before the material has set with abe® super brush cleaner
- Wash with soap and water
