Garden Route's trusted roof specialists
Waterproof your roof. Cool your home.
Professional liquid rubber application creates a flexible, seamless shield against leaks, UV exposure and South Africa’s demanding weather.
Why rubberize?
Your roof should protect you—not cost you.
Leaks, harsh UV exposure and trapped heat cause expensive damage. Wacko Rubber combines correct preparation with a flexible coating system designed to protect vulnerable surfaces.
UV & weather resistant
Flexible acrylic and industrial rubber systems built for sun, wind and driving rain.
Works across surfaces
Solutions for roof tiles, IBR, corrugated metal, wood, concrete, walls, parapets and more.
Our waterproofing range
The correct system for every surface.
Choose water-based Liquid Rubber for pitched run-off areas, solvent rubber for demanding surfaces where water may gather, and primers for reliable preparation and adhesion.
Professional application
From assessment to a seamless finish.
Roof assessment
We inspect surfaces and identify cracks, seams, screws and problem areas.
Preparation
The area is cleaned, dried and prepared with the correct bonding system.
Application
Coats are applied to the required thickness using brush, roller or spray.
Cure & inspect
After curing, the complete surface is checked for seamless coverage.

Water-based waterproofing rubber
Liquid Rubber
Pure acrylic, UV-resistant and flexible waterproofing for sloped roofs, roof structures, metal, wood, parapets, concrete, IBR and corrugated roofs. Use where water can run off—not where water gathers.
Flexible, seamless protection
- Acrylic-based waterproof seal product
- 100% paintable, UV and weather resistant
- Non-corrosive with strong adhesive properties
- Non-biodegradable, non-dripping and easy to apply
- Suitable for walls, pitched roofs, IBR, corrugated sheets, tiles, asbestos, wood and steel
Designed for run-off areas
Liquid Rubber is not recommended for areas where water dams or gathers. For flat roofs, box gutters and ponding conditions, review our Solvent Rubber system.
View Solvent RubberHow to apply
Preparation creates performance.
The final appearance should be seamless. Weather, surface condition and application method affect coverage and curing.
Clean & dry
Ensure the complete area is dry and clear of debris.
Bond problem areas
Apply Bonding Liquid to walls, crack seams, screws, joints, overlaps, ridge caps and gutters.
Apply two coats
Apply a thin first coat. Once completely dry, apply a thicker second coat to reach approximately 1.5–2mm total thickness.
Allow to cure
Total curing time is approximately 48 hours, depending on weather.
Coverage20L covers approximately 35–40m² on a flat surface with two coats applied.
ApplicationApply by paint brush, roller or airless compressor/spray machine.

Solvent-based waterproofing rubber
Industrial protection where water gathers.
Nanotech PVB industrial liquid rubber—a 100% vinyl rubber roof paint and coating engineered for UV resistance, long service and demanding waterproofing conditions.
Heavy-duty system
Built for flat and demanding surfaces.
Use on concrete slabs, metal, wood, IBR, corrugated steel and stainless steel. Unlike water-based Liquid Rubber, this system can be used where water gathers.
Broad adhesion
Suitable for almost any surface except glass, subject to correct preparation.
Ponding areas
Use on flat concrete slabs, box gutters and other areas where water can gather.
Industrial uses
Suitable for IBR and corrugated roofs, farm dams and ponds. Not suitable for high-traffic areas.
Professional assessment
Confirm compatibility before coating.
Solvent systems require careful surface assessment, preparation and safe application. Contact Wacko Rubber to confirm the correct primer, coating build and curing conditions.
Surface preparation systems
Primers & Bonding Liquid
Specially formulated preparation products improve adhesion, bridge cracks and protect challenging surfaces—creating the foundation for a smooth, durable topcoat.
Bind, prime and waterproof.
Designed to penetrate and bind surfaces previously painted with distemper, lime wash and cement paint before overcoating with emulsion paints.
- Acrylic based
- Mix into cement for use as a crack filler
- Use as primer for PVA, acrylic, enamel paint and Liquid Rubber
- Mix into plaster to improve strength
- Improves adhesion of cement-based decorative coatings
- Use as a waterproofing agent in ponds, parapet walls, patio screeds and slabs under pool paving
Better preparation
A topcoat is only as strong as the surface beneath it.
Correct cleaning, drying, crack treatment and priming reduce coating failure. Our team can help identify which preparation product suits your substrate and existing finish.

Protection in every detail.
Professional waterproofing begins with assessment and preparation, then finishes with careful coating around every seam, ridge, penetration and vulnerable area.
