Sunny Cove Fish Hoek Interior Painting

Documented Interior Painting in Sunny Cove, Fish Hoek

This case study documents a genuine interior repaint completed by Painters Cape Town at a private home in Sunny Cove, Fish Hoek from 18 to 26 May 2026.

Before painting started, the written inspection recorded visible mould, moisture-related symptoms, peeling and discoloured paint, wall cracks, movement at Rhinoboard ceiling and cornice junctions, failed bath and basin sealant and wear to painted doors, frames and skirting.

Protimeter readings ranged from 7.6% to 14.2%.

The project forms part of our wider Painters Fish Hoek evidence cluster and the regional False Bay Painters hub.

For comparison, our separate Fish Hoek Mountainside exterior painting project documents a completely different set of local conditions, including 13%–21% readings, exterior cracking, failed seals, waterproofing, deteriorated glazing putty and weathered timber.

What the Sunny Cove Inspection Documented

This was not treated as a simple colour-change project.

The original inspection recorded:

• Protimeter readings from 7.6% to 14.2%;
• visible mould across several ceilings and upper-wall areas;
• general damp-related symptoms;
• peeling and discoloured coating on selected walls;
• hairline and approximately 1 mm wall cracks;
• Rhinoboard ceilings;
• gaps between cornices and walls;
• gaps between cornices and ceilings;
• movement at these junctions during windy conditions;
• failed sealant around baths and basins; and
• chip marks and coating deterioration on doors, frames and painted skirting.

Each condition required the preparation method to match the substrate and defect rather than using one filler, one primer and one topcoat throughout the house.

7.6%–14.2% Protimeter Readings

The moisture readings are included because they form part of the genuine project evidence.

They should not be misinterpreted.

A meter reading does not automatically prove rising damp, a roof leak, a plumbing defect or condensation.

The correct interpretation depends on the position of the reading, visible staining, building construction, ventilation, recent moisture exposure and other site evidence.

For this reason, the project documents the readings and the visible symptoms without claiming a specific moisture mechanism that the available evidence does not establish.

Visible Mould Required Treatment Before Paint

The original photograph documents substantial visible mould across part of the ceiling and upper-wall area.

Applying decorative paint directly over active mould would merely conceal biological contamination beneath the new film.

The written specification therefore included fungicidal treatment using Dulux Weathershield Fungicidal Wash, followed by cleaning and rinsing before the subsequent preparation stages.

Stained surfaces could receive Dulux Universal Undercoat where specified to reduce stain migration through the final finish.

Ventilation Was Improved Before Painting

The owner had installed extractor fans before the painting work commenced.

This is important first-hand project context because paint cannot correct poor ventilation.

Where humid interior air repeatedly condenses on cooler surfaces, mould can return even after careful cleaning and repainting.

Improving ventilation before the repaint therefore addressed a building-use factor rather than expecting the coating system to solve the entire moisture environment.

If mould returns after painting, the cause should be investigated rather than repeatedly covering the symptom.

Protecting an Occupied Interior

The written scope began with protection of floors, furniture and surrounding finishes before preparation and painting.

Electrical switch and plug covers were removed where practical, while masking was used around junctions to maintain clean finishing lines.

These details are particularly important during interior painting in Cape Town, where clients may continue living in the property while work proceeds.

Hairline and Approximately 1 mm Wall Cracks

The project included both hairline and approximately 1 mm wall cracks.

The written preparation system specified alkali-resistant sealer at relevant fine cracks, followed by Dulux Rainshield as a flexible crack-treatment component where appropriate.

A thin layer of filler was then used to restore a smooth finish before sanding, priming and application of the decorative coatings.

Cracks were therefore treated as substrate defects before the walls were repainted.

Rhinoboard Ceiling and Cornice Movement

One of the more distinctive findings at this property involved the Rhinoboard ceilings.

The inspection recorded gaps between:

• cornices and walls; and
• cornices and ceilings.

The quotation associated these gaps with movement occurring during windy conditions.

That is important because a moving junction should not automatically be repaired using only a hard brittle filler.

Relevant gaps were specified for single-pack polyurethane sealant with approximately 25% flexibility.

This allows more movement than an ordinary rigid patching compound.

Ceiling Preparation and Painting

The Rhinoboard ceilings were prepared before decorative painting commenced.

Water-stained areas were specified for Universal Undercoat where required to help prevent staining from migrating through subsequent coatings.

After preparation, the quotation specified two coats of Dulux Paints Wall & Ceiling Paint to the Rhinoboard ceilings.

Interior Wall Preparation and Painting

Wall surfaces were inspected for cracks, holes, damaged plaster and other imperfections before priming and painting.

After the required preparation, the documented finishing specification was two coats of Dulux Luxurious Silk.

The finishing paint was therefore the final stage of the process—not the treatment for the underlying defects.

Damp-Affected Wall Preparation

The written project specification included Dulux Pre-Paint Dampshield for designated prepared damp-affected wall areas where applicable.

The specification contained additional treatment requirements for higher moisture ranges.

However, the actual readings documented at this Sunny Cove property were 7.6%–14.2%.

This page therefore does not use a generic product instruction to exaggerate the measured conditions at the property.

Paint products intended for damp-affected substrates remain preparation tools; they do not repair an active plumbing leak, roof defect, failed waterproofing system or other continuing water source.

Doors, Frames and Painted Skirting

The inspection documented chipped and worn areas on doors, frames and painted skirting.

The written preparation system included:

• repairing relevant cracks or junctions;
• filling chip marks;
• sanding repaired areas smooth;
• removing loose and flaking coating;
• feathering hard coating edges;
• spot priming exposed timber with Dulux Wood Primer;
• a full coat of Dulux Universal Undercoat; and
• two coats of Dulux Pearlglo Water Based Enamel.

This provides a coating system appropriate to higher-contact painted joinery rather than using ordinary wall paint as a shortcut.

Bath and Basin Sealant Repairs

Failed sealing was documented around baths and basins.

The written scope specified removal of failed material and resealing of relevant joints using flexible single-pack polyurethane sealant.

A decorative coating cannot correct a defective wet-area joint—the joint itself has to be repaired where it falls within the painting scope.

Supplier Approval, Specifications and Warranty Options

Painters Cape Town is approved by major paint suppliers.

Where technical involvement is appropriate, we can work to formal supplier painting specifications rather than relying only on a contractor-selected generic system.

Supplier-backed warranties are available on qualifying projects.

Qualifying new-build projects on correctly prepared raw plaster can receive supplier-backed specifications of up to 10 years where the complete specified system is followed from the initial primer through preparation, waterproofing and finishing coats.

For qualifying redecoration or repainting, supplier-backed warranties are typically 7–8 years, depending on the supplier and written specification, because the original preparation and primer system beneath existing coatings cannot always be verified.

Formal warranties always remain subject to the supplier’s written conditions, maintenance requirements and exclusions.

This Sunny Cove interior case study is not being presented as a formal supplier-warranty project because the available project records do not establish that status.

Supplier approval at company level should not be confused with supplier endorsement of every individual job.

Completed Sunny Cove Interior

The completed interior represents the visible result of a preparation process that considered mould, ventilation, moisture readings, ceiling movement, wall cracking, wet-area joints and different painted substrates.

Continued ventilation remains important after completion.

If mould, staining or peeling returns, the moisture or ventilation conditions should be investigated rather than repeatedly applying more paint over the symptom.

What This Sunny Cove Project Demonstrates

This project provides particularly useful first-hand evidence because it documents interior maintenance conditions that are completely different from the exterior problems at our Fish Hoek Mountainside project.

The Sunny Cove case study records:

• actual 7.6%–14.2% Protimeter readings;
• visible mould rather than an assumed mould problem;
• ventilation improvement before repainting;
• Rhinoboard ceiling and cornice movement;
• flexible movement-joint repairs;
• interior crack preparation;
• wet-area seal repairs;
• substrate-specific ceiling, wall and joinery finishes;
• a named working foreman;
• original before-and-after photography; and
• a documented completion period in May 2026.

Together with the Fish Hoek Mountainside exterior project, this creates genuine evidence of both interior and exterior painting work completed in Fish Hoek.
