Roof and Exterior Painting at a Paradyskloof Home, Stellenbosch

Paradyskloof Roof and Exterior Painting Project in Stellenbosch

Painters Cape Town completed this documented Paradyskloof roof and exterior painting project at a private residential home in Stellenbosch during the 17 August–2 September 2026 project window.

The scope was considerably broader than an ordinary house repaint.

It included the tiled roof, main-building and garage exterior walls, painted timber fascia boards, varnished garage doors, exterior windows and doors, waterproofing of vulnerable horizontal surfaces, damp-related preparation and sealing around openings and external fittings.

Protimeter readings taken during the assessment ranged from 10.4% to 15.6%.

The physical inspection also identified map cracking, cracks on vertical and horizontal surfaces, hollow plaster, deteriorating window and door seals, moisture-related coating discolouration, ageing waterproofing, failed expansion-joint sealant, mould on roof and wall surfaces and chalky roof tiles.

To protect the homeowner’s privacy, no client name or street address is published.

This project now forms important first-hand evidence for our Painters Stellenbosch, Roof Painting Stellenbosch, Exterior Painters Stellenbosch and Waterproofing Stellenbosch services.

What the Paradyskloof Inspection Found

The repaint was approached as a building-maintenance project because several different causes of coating deterioration were visible.

• Protimeter readings from 10.4% to 15.6%.
• Map cracking on exterior masonry.
• Cracks on walls, windowsills, parapets and expansion-joint areas.
• Hollow plaster detaching from some exterior walls.
• Window and door sealants beginning to fail.
• Discoloured coating associated with moisture ingress and alkali-related deterioration.
• Aged waterproofing on horizontal surfaces requiring renewal.
• Deteriorated expansion-joint sealant.
• Mould on roof tiles, walls and parapet areas.
• Chalky roof tiles requiring substrate stabilisation before coating.

10.4%–15.6% Protimeter Readings

The recorded masonry readings ranged from 10.4% to 15.6%.

These measurements were interpreted together with the physical condition of the walls rather than being treated as a stand-alone diagnosis.

Cracks, windowsills, parapets, sealants, expansion joints, foundation-wall construction and other building details can all influence how water enters or moves through exterior masonry.

The inspection therefore combined measurable moisture information with visible evidence before the preparation system was specified.

For more examples of how coating failure is diagnosed rather than simply painted over, see our Paint Failure Stellenbosch guide.

Alkali-Related Coating Discolouration

Selected exterior areas displayed discolouration consistent with moisture movement through cementitious surfaces and associated alkaline salts.

When moisture travels through plaster, soluble salts can migrate toward the surface and contribute to staining, powdering and deterioration of the paint film.

The project remedy therefore did not rely on topcoat paint alone.

The written specification combined crack preparation, sealing, horizontal waterproofing and damp-related coating preparation where applicable.

High-Pressure Cleaning of the Walls and Roof

The roof and suitable exterior wall surfaces were high-pressure cleaned before repainting.

The purpose was to remove loose and flaking coating material, grime, chalky deposits and biological contamination.

Where high-pressure cleaning was unsuitable, the specification allowed for manual cleaning with the specified ProGold GP Cleaner solution.

Fungal Treatment on the Roof and Walls

Mould was recorded on roof tiles, walls and parapet areas.

The roof tiles were particularly affected.

Fungus-affected areas received the specified ProGold Fungal Wash treatment before further preparation proceeded.

Painting directly over active biological contamination would leave an unstable and contaminated interface beneath the new coating.

Re-Waterproofing Horizontal Surfaces

The previous waterproofing on vulnerable horizontal surfaces had been completed several years earlier and had reached a stage where renewal was required.

Parapet tops, windowsills and similar upward-facing masonry were therefore included in the waterproofing preparation.

The documented system specified two coats of Dulux Rainshield, with the second coat applied perpendicular to the first.

This perpendicular application assists consistent coverage of the treated surface.

This documented work also supports our dedicated Waterproofing Stellenbosch service, where we explain the preparation and treatment of vulnerable masonry, joints and exposed horizontal surfaces before repainting.

Why Horizontal Masonry Matters in Stellenbosch

Unlike vertical walls, horizontal parapets and windowsills receive rainfall directly and can hold moisture for longer periods.

Small cracks or deteriorated waterproofing on these surfaces can allow moisture to enter the wall below.

This is particularly relevant during Stellenbosch’s wetter winter months, when repeated rain can expose weak waterproofing details before warmer conditions later accelerate visible coating deterioration.

Hairline Cracks

Hairline cracks up to approximately 1 mm were specified for alkali-resistant sealing followed by Dulux Rainshield worked into the crack.

Where walls displayed multiple spiderweb cracks, the affected areas received additional flexible Rainshield preparation after the specified primer.

This method treats the crack network before the decorative exterior topcoat is applied.

Wider Plaster Cracks

Plaster cracks between approximately 1 mm and 5 mm required a different preparation method.

Suitable cracks were opened to a V-shaped joint, cleaned and repaired with compatible masonry patching material.

Once the repaired area was smooth and dry, the specified Rainshield system was applied across the repaired zone.

This prevents a wider plaster defect from being treated as though it were merely a superficial hairline crack.

Map Cracking

Map or spiderweb cracking was recorded on exterior areas.

The specification included flexible Dulux Rainshield preparation over the affected surfaces.

Map cracking is important because a network of many fine defects can create substantially more vulnerable surface area than one isolated crack.

Our Wall Preparation Stellenbosch guide explains why hairline cracks, map cracking, wider cracks and movement joints should not all receive the same repair.

Hollow Plaster Required Removal and Replastering

One of the strongest technical features of the Paradyskloof project was the presence of hollow plaster on some exterior walls.

Hollow plaster cannot reliably support a new coating because the plaster itself is no longer firmly bonded to the wall underneath.

The documented remedial method required the loose or hollow plaster to be removed until firmly bonded material was reached.

The exposed masonry was then cleaned before a bonding agent was applied.

Deeper areas could receive a suitable base plaster before the finishing plaster was applied flush with the surrounding wall.

After curing, the repaired plaster was sanded and received Dulux Plaster Primer before final painting.

This is fundamentally different from simply filling visible surface cracks while leaving detached plaster in place.

Window and Door Perimeter Sealing

The existing sealant around selected windows and doors was beginning to deteriorate.

The specification required failed sealant to be removed where necessary and replaced with single-pack polyurethane sealant with approximately 25% flexibility.

Exterior wall and light-fitting penetrations were also included in the sealing process where required.

Small openings around frames and fittings can become significant rainwater-entry points over time.

Expansion Joints Required Flexible Resealing

Expansion joints showing failed or deteriorated sealant required resealing.

These joints were treated with flexible polyurethane rather than rigid plaster repair because they are intended to accommodate movement.

Rigidly filling an active movement joint can result in renewed cracking as the structure moves again.

Damp-Related Wall Preparation

The written specification included Dulux Pre-Paint Dampshield on prepared exterior wall areas affected by cracks or damp-related conditions.

Where substrate readings reached the specified elevated-moisture range, additional spot treatment was required.

Prepared bare areas received the specified Dulux Dampshield system and curing period before topcoating.

This was part of a wider preparation system and was not a replacement for repairing cracks, failed seals or waterproofing defects.

For Stellenbosch-specific moisture-entry details and preparatory waterproofing, visit our Waterproofing Stellenbosch page. Our Damp Proofing Cape Town page provides broader information about damp-related services and treatment limitations.

Foundation-Wall Moisture Limitations

The inspection also recorded moisture-related discolouration below weep-hole and expansion-joint levels on certain foundation-wall areas.

These walls were exposed to moisture from the backfilled side without an effective damp-proof separation.

Dulux Dampshield formed part of the specified preparation, but coating the accessible face cannot permanently stop moisture that continues migrating from behind the wall.

The quotation therefore specifically limited responsibility for future moisture-related discolouration, bubbling or peeling caused by continuing moisture migration.

Boundary and Garden Wall Limitations

The project documentation also records the same practical limitation for boundary and garden walls without effective damp-proof separation from ground moisture.

A suitable breathable or remedial coating can improve the painted face, but it cannot create a missing damp-proof barrier inside or behind the masonry.

Where ground moisture continues moving through the wall, future discolouration, bubbling or peeling remains possible.

These practical limitations are discussed further on our Boundary Wall Painting Stellenbosch page, including why boundary walls and stable main-building walls should not automatically be treated as identical coating environments.

Painted Timber Fascia Boards

The painted fascia boards required timber-specific preparation.

Loose and flaking paint was removed, the woodwork was sanded to a uniform finish and hard coating edges were feathered.

Exposed bare timber received Dulux Wood Primer, followed by a full coat of Dulux Universal Undercoat where specified.

The prepared fascia boards were finished with two coats of Dulux Pearlglo Waterbase.

Varnished Garage Doors, Windows and Exterior Doors

The property’s varnished timber required a different maintenance system from the painted fascia boards.

The existing varnished surfaces were lightly sanded with scouring pads or fine-grit sandpaper to reduce the sheen and create a suitable key.

The surfaces were required to be clean, dry and sound before receiving two coats of Dulux Woodgard varnish.

This included the relevant garage doors, window exteriors and exterior faces of doors within the project scope.

Exterior Wall Finish

After the cleaning, plaster repairs, crack preparation, waterproofing, sealing and damp-related work were completed, the main-building and garage walls received two coats of Dulux Wallguard.

The finished wall coating was therefore the final part of a much larger preparation process.

Tiled Roof Preparation at Paradyskloof

The Paradyskloof project provides strong first-hand evidence of tiled roof painting in Stellenbosch.

The roof tiles showed both extensive mould contamination and surface chalking before preparation.

Those conditions needed to be addressed before the new roof coating was applied.

Stabilising Chalky Roof Tiles

After cleaning and fungal treatment, the chalky roof tiles received a full coat of Dulux Bonding Liquid.

The purpose was to neutralise the chalkiness and stabilise the roof surface before topcoating.

This is important because applying roof paint directly over a weak powdery surface can leave the new coating dependent on an unstable layer underneath.

Two Coats of Charcoal Dulux Roofguard

The stabilised roof tiles were specified for two coats of charcoal Dulux Roofguard.

The roof photograph documents the coating work taking place on the actual Paradyskloof property.

The named coating products are included because they formed part of the written project specification. Their inclusion does not imply manufacturer endorsement of Painters Cape Town or this webpage.

Roof Coating Is Not a Leak Repair

This project involved preparation and protective coating of suitable roof tiles.

Roof painting should not be confused with structural roof repair or waterproofing of an active leak.

Broken tiles, defective flashings, leaking roof penetrations or other active roof defects should be repaired separately before a coating system is relied upon.

Paradyskloof and Rozendal Farm: Two Different Stellenbosch Roof Systems

Paradyskloof gives us a technically different roof example from our documented Rozendal Farm project.

The Paradyskloof roof was a tiled residential roof affected by mould and chalking. After cleaning and fungal treatment, the prepared substrate was stabilised with Dulux Bonding Liquid before two coats of charcoal Dulux Roofguard.

The Rozendal Farm exterior and roof project involved corrugated roof sheets requiring biological-growth removal, corrosion preparation, HydroEtch preparation and Dulux Roofguard.

These two genuine projects give our Roof Painting Stellenbosch page evidence across two very different roof substrates rather than one generic roof-painting claim.

What This Paradyskloof Project Demonstrates

• A roof-and-exterior repaint should begin with an inspection rather than colour selection.
• Chalky roof tiles need stabilisation before final roof coating.
• Mould should be treated before coating.
• Hollow plaster requires removal and replastering rather than cosmetic filling.
• Hairline cracks, wider cracks, map cracking and expansion joints require different treatments.
• Old parapet and windowsill waterproofing eventually requires maintenance.
• Failed window and door seals can become moisture-entry routes.
• Painted and varnished timber require different preparation systems.
• Continuing moisture from behind backfilled or ground-contact walls can limit coating performance.

Paradyskloof and Wall Preparation Stellenbosch

This project is one of our strongest practical examples of why wall preparation deserves its own technical guide.

The same property contained map cracking, wider cracks, hollow plaster, failed sealants, movement joints, waterproofing deterioration and moisture-related coating symptoms.

Each defect required a different preparation response.

Paradyskloof and Paint Failure Diagnosis

The Paradyskloof inspection also demonstrates why the visible coating is not always the underlying problem.

Peeling paint can be associated with unstable coating or moisture. Discolouration can relate to moisture movement. Cracking can create water-entry routes, while hollow plaster represents loss of the plaster bond rather than a paint defect.

These conditions need to be identified before the final coating system is selected.

Why This Project Cannot Be Priced by Square Metres Alone

Paradyskloof is also a useful example of why house-painting cost cannot be determined accurately from floor area or wall area alone.

The project combined:

• Tiled-roof cleaning and painting.
• Fungal treatment.
• Roof-substrate stabilisation.
• Hollow-plaster removal and replacement.
• Different crack-repair systems.
• Horizontal waterproofing.
• Sealant replacement.
• Expansion-joint work.
• Damp-related preparation.
• Painted timber fascia preparation.
• Varnished timber maintenance.
• Exterior wall repainting.

The documented source available for this page does not provide a reliable project-total figure, so no project price is claimed here.

The important point is that each of these preparation and substrate requirements affects labour, materials and project duration.
