Quick answer: Table View, Blouberg and Big Bay homes face four damp pressures — high atmospheric humidity, salt-laden air, prevailing southwester rain, and overnight condensation cycles. The fix is exterior waterproofing with Rhinoluxe Shield Exterior on the worst-exposed walls, plus interior Shield Indoor on cold-spot walls.
Four climate factors that drive damp
- Atlantic humidity. Table View sits 1–2 km from the coastline. Relative humidity sits in the 70–85% bracket for most of the year.
- Salt air. Salt particles deposit on walls and roofs, attract moisture, and degrade cheap paint binders.
- Southwester driving rain. Winter cold fronts push rain horizontally into south- and southwest-facing walls.
- Diurnal temperature swings. Cold nights, warm days — vapour condenses on cold internal walls overnight, especially north- and east-facing rooms.
How to diagnose what kind of damp you have
| Sign | Likely cause | Treatment |
|---|---|---|
| Wet patches on outside walls after rain | Penetrating damp through failed render or paint | Strip back, Bond and Key, Shield Exterior ×2 |
| Tide-line halfway up internal wall | Rising damp (failed DPC) | Source repair + Shield Indoor |
| Black mould in corners and behind furniture | Condensation | Improve ventilation + Shield Indoor |
| Peeling paint, salt deposits | Damp + cheap paint binder | Strip, treat, switch to pure-acrylic Shield system |
Exterior fix — Shield Exterior
For walls that get hit by southwester storms, the right system is one coat of Rhinoluxe Bond and Key primer followed by two full coats of Rhinoluxe Shield Exterior. Shield Exterior uses a 100% acrylic binder with flexible polymers, so it bridges hairline cracks that would otherwise let water through.
Interior fix — Shield Indoor
For cold-spot internal walls where condensation builds up, follow the four-step interior system: mould wash → Bond and Key (if needed) → two coats Shield Indoor → two coats Premium Pure Acrylic Semi-Gloss or Low Sheen.
Why coastal homes need pure-acrylic specifically
Styrenated acrylics (most cheap "acrylic" paints) chalk and yellow under salt-laden UV within 3–4 years. A pure-acrylic binder costs more upfront but lasts 7–10 years on exterior walls in Table View conditions — meaning fewer repaints, less scaffold cost, and a cleaner-looking home for longer.
