Exterior Wall Waterproofing in Plattekloof
Painters Cape Town provides inspection-led waterproofing preparation and protective treatment of suitable exterior masonry in Plattekloof. Our work includes exposed horizontal surfaces, parapet tops, windowsills, boundary-wall copings, appropriate crack repairs and defective seals associated with exterior painting.
With 27 years of painting experience, full-time employed painters and written diagnostic quotations, we assess visible water-entry routes before specifying suitable repairs and coatings.
Our completed Baronetcy Estate and Plattekloof 2 projects provide genuine evidence of waterproofing work specified as part of substantial exterior repainting projects. The original quotations recorded moisture observations, defective seals, cracks, unprotected horizontal surfaces and limitations around continuing ground moisture.
Real Plattekloof Projects with Waterproofing Specifications
Both projects were completed in 2026. The photographs below show the completed exterior properties; the inspection findings and treatment specifications are drawn from their original written quotations.
Baronetcy Estate – Exposed Masonry and Failed Seals
Completed Baronetcy Estate exterior painting project, March 2026.
Completed project period: 9–24 March 2026.
Recorded Protimeter readings: Minimum 9, maximum 13.
The original inspection identified cracks in walls and windowsills, defective sealant around windows and doors, unsealed expansion joints, unwaterproofed horizontal surfaces and moisture-related coating discolouration.
Specified treatment included preparation and sealing of appropriate defects, Dulux Rainshield on designated horizontal masonry and Dulux Dampshield where appropriate to the affected substrate.
The written quotation also explained why ongoing ground moisture in certain boundary and foundation walls cannot be permanently stopped by decorative coatings.
Completed Plattekloof 2 exterior painting project, February 2026.
Completed project period: 2–11 February 2026.
Recorded Protimeter readings: Minimum 15, maximum 18.1.
The original quotation recorded map cracking, defects in vertical and horizontal masonry, failed window and door sealant, open expansion joints, weathered windowsills and horizontal surfaces that had not been adequately waterproofed.
The written specification included Dulux Rainshield for relevant horizontal surfaces, suitable sealing and crack preparation, and Dulux Dampshield for specified moisture-affected masonry.
It was prepared with reference to a Dulux warranty specification. This does not, on its own, establish that a separate manufacturer’s warranty certificate was issued.
Common Sources of Water Entry on Plattekloof Exteriors
Some apparent paint failures are caused by moisture entering the masonry, rather than by the quality of the finishing paint alone. The original Baronetcy and Plattekloof 2 inspections recorded several different potential entry routes.
Parapet Tops and Horizontal Wall Surfaces
Exposed tops of parapets, retaining features and exterior walls may experience standing or wind-driven rain. Where those surfaces are unprotected or cracked, moisture can enter and affect adjoining painted vertical masonry.
Our specifications included Dulux Rainshield treatment of suitable parapet tops, windowsills and boundary-wall copings after the required preparation.
Windowsills
Windowsills are exposed to sunlight, rainwater and repeated wetting. Cracks or deteriorated coatings can allow moisture to penetrate adjacent plaster.
Both original Plattekloof quotations recorded deterioration around windowsill or horizontal areas. The appropriate repairs and protective coating system depend on the actual substrate and defect.
Failed Window and Door Sealant
Sealant around windows and doors can lose adhesion, crack or deteriorate over time. When gaps develop, water may penetrate behind adjacent finishes.
The project quotations specified removing deteriorated sealant and resealing applicable joints with a compatible single-pack polyurethane sealant.
Expansion and Movement Joints
Movement joints are intended to accommodate changes within the building. If their sealant fails, water may enter the gap and affect surrounding plaster and paint.
Our original project specifications addressed relevant failed expansion joints separately from ordinary plaster cracks.
Cracks in Masonry
Hairline cracks, map cracking and wider plaster defects require assessment before repainting. The original specifications used different repair methods for fine cracks and larger plaster cracks, including suitable sealers, masonry repair materials and protective treatment where specified.
Where movement is continuing or a defect is structural, an appropriate specialist assessment may be necessary. Decorative waterproofing coatings are not substitutes for correcting structural defects.
Dulux Rainshield and the Specified Horizontal Waterproofing System
Both Plattekloof project quotations included Dulux Rainshield for suitable exposed horizontal masonry surfaces.
The specifications required the substrate to be prepared first and included two coats applied in different directions for the designated surfaces.
These applications were specified for selected parapet tops, windowsills and boundary-wall copings, rather than as a universal treatment for every wall surface.
Cracks, failed seals, unsuitable previous coatings and other defects must be addressed as part of the agreed preparation. A waterproof coating applied over a continuing defect may not resolve the source of water entry.
Damp Proofing Is Not the Same as Waterproofing
The original project quotations also specified Dulux Dampshield for designated damp-related areas, together with written moisture-related limitations.
Rainshield and Dampshield were therefore specified for different purposes within the overall protective coating systems.
A moisture-affected wall must be assessed to distinguish water entering through an exposed surface or defective joint from moisture continuing to migrate through the wall from the ground or from behind.
Boundary Walls Without a Damp-Proof Barrier
Both original quotations specifically identified boundary walls without an effective barrier separating the masonry from ground moisture.
Where moisture continues entering from the soil or behind the wall, even a properly prepared breathable coating may experience staining, bubbling or deterioration in the future.
The quotations expressly excluded coating failures caused by continuing ground moisture from the relevant coating warranty.
Foundation Walls and Backfilled Areas
The original inspections also identified moisture-related discolouration below expansion-joint or weep-hole levels, where masonry can be exposed to moisture from backfilled areas.
Dulux Dampshield was specified for the relevant prepared areas, but the quotations did not promise that the coating would permanently eliminate moisture migrating through the masonry.
Our approach is to explain these limitations before quoting rather than promising that paint can permanently cure every damp condition.
Alkali Attack and Moisture-Related Discolouration
Both original quotations recorded moisture-related discolouration associated with alkali attack. This can occur when moisture moves through cement-based substrates and affects the paint film.
Applying new finishing coats without first addressing the relevant entry routes and substrate condition may result in a recurring problem.
Our project specifications therefore combined appropriate crack preparation, joint sealing, horizontal waterproofing and substrate-specific treatment before the decorative exterior finishes.
How We Assess and Quote Exterior Waterproofing Work
Inspection: We examine the relevant masonry, cracks, joints, exposed horizontal areas and visible moisture symptoms.
Diagnostic observations: We record relevant conditions and Protimeter readings where appropriate.
Assessment of water-entry routes: We distinguish defects that may be treated within the proposed scope from continuing moisture or structural problems.
Written specification: We identify the agreed preparation, repairs, sealing, products and limitations.
Preparation and treatment: Our employed painters complete the specified work under working-foreman supervision.
Final review: We inspect the completed work against the agreed scope.

What waterproofing work do you undertake in Plattekloof?
We inspect and treat suitable exterior masonry and painting-related water-entry defects, including exposed parapet tops, windowsills, boundary-wall copings, cracks and defective sealant within the agreed scope.
Have you completed waterproofing-related work in Plattekloof?
Yes. Our completed exterior painting projects at Baronetcy Estate and Plattekloof 2 included written specifications for horizontal waterproofing, joint sealing, crack repairs and designated damp-related areas.
Which product was specified for horizontal surfaces?
The original project quotations specified Dulux Rainshield for suitable exposed horizontal masonry, including designated parapet tops, windowsills and boundary-wall copings.
Can failed sealant around windows cause damp-related paint failure?
Yes. Defective window or door seals can allow rainwater into adjacent masonry. Both original Plattekloof inspections identified failed sealant requiring suitable preparation and resealing.
Do you repair expansion joints?
We assess appropriate failed sealant in expansion joints and specify suitable flexible resealing where it forms part of the agreed painting and protective-treatment scope.
Is Dulux Dampshield the same as Dulux Rainshield?
No. Our original specifications used Rainshield for designated exposed horizontal waterproofing and Dampshield for specified moisture-affected masonry. Product selection depends on the surface and condition.
Can waterproof paint permanently stop rising damp in boundary walls?
No. Where a wall lacks an effective damp-proof barrier and moisture continues entering from the ground or behind, decorative coatings cannot permanently eliminate that moisture source.
Do you use moisture readings during inspections?
Yes, where appropriate. The original Baronetcy Estate quotation recorded Protimeter readings of 9 to 13, and Plattekloof 2 recorded readings of 15 to 18.1. Readings are interpreted alongside visible site conditions.
Do you provide a written specification?
Yes. Our quotations include diagnostic observations, specified preparation, suitable materials, the agreed scope and relevant exclusions or limitations.
