Double-storey home | full exterior repaint
A weather-worn double-storey exterior stripped back, prepared and repainted in a clean two-tone scheme.
Approved applicator & authorised reseller, Durbanville, the Northern Suburbs and greater Cape Town
Rubber Sealant® Liquid Rubber goes on as a liquid and cures into one seamless rubber skin with no seams, no laps and no torch. We are an approved applicator and an authorised reseller, so you can buy the drum in Durbanville, or hand us the roof. Prices, coverage and the small print are all on this page.
Problem & approach
Most waterproofing sold in Cape Town fails for the same three reasons, and none of them are the weather. The first is seams: any system that comes in a roll has joins, and a join is a future leak with a date on it. The second is preparation: a coating rolled over a dusty, unprimed, chalked surface has nothing to grip, so it looks perfect on handover day and lifts off in sheets by the second winter. The third is thickness. A product that needs three coats to reach its cured build gets one thin one, because the person applying it is paid by the job and not by the millimetre. Then there is the shopping problem. Walk into a hardware chain and you will be sold a bucket of white acrylic roof paint with the word waterproof on the front, at a price that looks reasonable until you learn that it is a paint, not a membrane, and that it has no guarantee behind it worth the name.
Rubber Sealant® Liquid Rubber is a water-based liquid rubber membrane. It is brushed or rolled on straight from the drum, three coats, and cures to roughly 3mm of flexible rubber that moves with the building instead of cracking with it. Because it goes on wet, it seals around every bolt head, lap, upstand, pipe and awkward corner as one continuous piece. We are an approved applicator and an authorised reseller, which means two things for you. If you are doing the work yourself, you buy the same drums we use, at the manufacturer's recommended prices, with the correct primer and the honest coverage figures instead of the optimistic ones on the tin. If you would rather not be on a roof in February, we apply it: inspection, written scope, one fixed price for the whole job, three coats built to specification, guarantee documentation at handover.

Colour
Black is the standing colour, and Rubber Sealant® is also mixed in 14 standard colours, so you do not pay for a top coat to get a colour. Need something off the chart? It can be custom mixed on request. The swatches above are an illustration, not a stock list: ask us for the current colour chart and we will confirm the colour with your quote.

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.

Written price: product list, or one fixed price for the whole job
Collection arranged in Durbanville, or a site date booked
Clean and dry the surface, then prime it correctly
