Williams & Co Paint Contractors

Every roof surface, Durbanville, the Northern Suburbs and greater Cape Town

Rubber paint is not one job. It is six, and each surface has its own rules.

Metal, tile, slate, concrete, flat and asbestos sheeting all take liquid rubber, and all of them take a different primer, a different coverage figure and a different amount of preparation. Get the primer wrong and the best product in the country peels off anyway.

Problem & approach

Where these projects go wrong, and how we handle them.

The usual problem

Almost every early failure we are called out to comes down to the same mistake: the right product, put onto the wrong preparation. Rusted metal primed as though it were galvanised. Roof tile treated like smooth concrete, so a drum meant to cover 17 m² was stretched over 40. A painted surface coated without anyone checking whether the old paint was still holding. It all looks identical the day it is finished. That is the problem with waterproofing: the difference between a good job and a bad one is completely invisible for about eighteen months, and then it rains properly.

Our approach

So we start with the surface, not the product. Metal, including galvanised, Chromadek, IBR and corrugated, takes Etch Primer Rust Supreme, after the loose rust is off. Concrete, plaster, brick, roof tile, slate, old torch-on, sound paint and wood take Bonding Liquid Super+. Never both, never neither. Then the coverage figure changes with the surface. At the manufacturer's three coats a 20 litre drum covers about 40 m² on smooth flat surfaces, about 33 m² on metal sheeting, about 27 m² over old torch-on, about 20 m² on concrete or brick, about 17 m² on roof tile and about 13 m² on slate. Then the details: bolts and screws on sheeting, ridges and valleys on tile, upstands and outlets on flat roofs. Those get reinforced first, because that is where nearly every leak actually starts. Only then do the three coats go on.

What may be included

Scope you can actually read.

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.

  • Surface identified properly, including what is already on it
  • Correct primer named and used: Etch Primer Rust Supreme on metal, Bonding Liquid Super+ on everything else
  • Loose rust, flaking paint, blisters and lifting laps removed before priming
  • Coverage calculated at three coats for that specific surface
  • Bolts, screws, laps, ridges, valleys, upstands, outlets and cracks reinforced first
  • Three full coats of Rubber Sealant®, roughly 3mm cured
  • Black plus fourteen standard colours at no extra cost
  • Guarantee documentation at handover

Products we work with

The Systems Behind the Work.

  • Rubber Sealant® logo

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

  • Plascon logo

    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.

Honest limits

What we will tell you up front.

A proper contractor should be honest about what a service can and cannot do. These are the things we will always flag.

  • Structure comes first. Perforated sheets, rotten timber, broken tiles and sagging purlins are repaired or replaced before any coating is quoted.
  • Liquid rubber is the only waterproofing system we apply. We do not install torch-on membranes and we do not do injection damp courses.
  • We do not remove, cut, drill or dispose of asbestos sheeting. We seal sound sheets in place.
  • Rubber Sealant Aqua is the product for holding water in, such as dams and ponds, and is not for roofs. A pool shell takes Rubber Sealant Splash.
  • The 13-year manufacturer product guarantee applies only where the manufacturer inspects, the system is specified correctly, the application is certified to thickness and the maintenance conditions are met. Individual products applied on their own carry a shorter product guarantee.
  • Any asbestos-cement area is excluded from ordinary cleaning and preparation methods. South African asbestos rules prohibit cleaning or preparing asbestos-cement surfaces.
