Prices & coverage, Durbanville, the Northern Suburbs and greater Cape Town
R1,990 a drum is either R50 a square metre or R150 a square metre, and the only thing that decides which is the surface you are putting it on. Every price and every coverage figure is on this page, so you can work out your own number before you phone anyone.
Problem & approach
Waterproofing pricing in South Africa is deliberately hard to compare. Product prices are published per pack, coverage is published per coat, and jobs are quoted per square metre, so the three numbers never line up. That gap is where the cheap quote lives. Somebody prices your roof at R70 per square metre and it sounds like a bargain until you work backwards: at that rate there is not enough product on the roof to reach a membrane thickness, never mind primer, never mind three coats, never mind the labour to do the detail properly. Meanwhile the honest quote looks expensive for reasons nobody has explained, so it loses.
So here is all of it, in the open. Rubber Sealant is R199 for 1L, R790 for 5L and R1,990 for a 20L drum, including VAT. Bonding Liquid Super+ runs R189, R490, R890 and R1,650 for 1L, 5L, 10L and 20L. Etch Primer Rust Supreme, the metal primer, is R195, R750, R1,450 and R2,390. Snow White Cooling Agent is R299, R890 and R2,460. Coverage at the manufacturer's three coats: about 40 m² a drum on a smooth flat surface, 33 m² on metal sheeting, 27 m² over old torch-on, 20 m² on concrete or brick, 17 m² on roof tile, 13 m² on slate and about 3 m² on thatch. Divide the drum price by your coverage and you have your true product cost per square metre, and it lands roughly between R50 and R150 before primer. Supplied and applied by us, waterproofing starts from R185 per m², and asbestos encapsulation from R285 per m², always as one fixed price for the whole job rather than a rate that drifts.
Coverage at three coats
| Surface | 20L drum covers | Primer it needs |
|---|---|---|
| Smooth, flat surface | about 40 m² | Bonding Liquid Super+ |
| Galvanised or Chromadek sheeting | about 33 m² | Etch Primer Rust Supreme |
| Painted steel or painted metal | about 33 m² | Etch Primer Rust Supreme |
| Raw, bare or rusted metal, IBR, corrugated, zinc | about 33 m² | Etch Primer Rust Supreme |
| Torch-on membrane | about 27 m² | Bonding Liquid Super+ |
| Concrete, brick or slab | about 20 m² | Bonding Liquid Super+ |
| Roof tile or Harvey tile | about 17 m² | Bonding Liquid Super+ |
| Slate tile | about 13 m² | Bonding Liquid Super+ |
| Thatch | about 3 m² | Bonding Liquid Super+ |
Figures are the manufacturer's, at the three coats the guarantee assumes. Rougher and more porous surfaces take more. Primer works out at roughly 6 m² a litre.

What may be included
The exact line items on your quote depend on the site inspection. This is the shape of what a typical project of this type includes.
Products we work with

Approved applicator and authorised reseller of Rubber Sealant® Liquid Rubber.

Our preferred paint on most projects.
We are not a Plascon approved applicator. Plascon is simply the paint we choose to specify for its quality and track record, and we will recommend a different system where a project calls for it.
Our process
Work out your area, surface by surface
Pick your coverage figure from the surface table
Divide drum price by coverage for product cost per m²
Add the correct primer at roughly 6 m² a litre
Round up to whole packs, because that is how it is sold
Or send us the numbers and we do all of it and confirm stock
