Living near the ocean has its perks—fresh sea air, stunning views, and a relaxed coastal lifestyle. However, the same conditions that make Hermanus special also create challenges for homeowners, especially when it comes to maintaining exterior walls, roofs, doors, and trims.
Salt in the air, strong sun exposure, and constant humidity can quickly damage standard paint products.
That is why choosing the right exterior paint in Hermanus is not just a cosmetic decision—it is a long-term investment in the protection and lifespan of your home.
Whether you’re repainting a beach house, sealing a holiday home, or refreshing a commercial building, the right paint makes all the difference in durability, appearance, and maintenance costs.
In this guide, we’ll explore the climate challenges you need to consider, the best exterior paint options for coastal homes, how to prepare and apply them correctly, and where to find locally approved products and expert advice in Hermanus.
Coastal Climate Challenges: Salt, Sun & Humidity
Hermanus’s coastal location exposes buildings to weather conditions that can shorten the lifespan of exterior paint if the wrong products are used.
Key Environmental Factors:
- Salt-laden air – causes corrosion, blistering, and premature peeling.
- High UV exposure – leads to fading, chalking, and surface breakdown.
- Moisture and humidity – can cause mould, mildew, and bubbling paint.
- Strong winds – carry abrasive sand and dust that wear away coatings.
Because of these conditions, the best exterior paint in Hermanus must be specially designed for coastal environments.
Standard household paints often fail within a few seasons, resulting in constant repainting and unnecessary repair costs.
Top Exterior Paints & Finishes for Coastal Homes
Not all paints offer the same level of protection. In Hermanus, durability and weather resistance are essential.
The following types of paint and finishes perform best in seaside environments:
1. 100% Acrylic Exterior Paints
- Flexible and crack-resistant
- Excellent UV and weather protection
- Long-lasting colour retention
2. Elastomeric Coatings
- Ideal for walls with fine surface cracks
- Waterproof yet breathable
- Expands and contracts with temperature changes
3. UV-Resistant Roof Paints
- Reflects sunlight to reduce heat absorption
- Protects tiles, metal sheets, and asbestos roofs
- Available in anti-fungal and anti-rust formulas
4. Marine-Grade Varnishes & Sealers (for wood)
- Prevents rot, swelling, and saltwater damage
- Enhances natural wood grain
- Used on decks, doors, shutters, pergolas
5. Anti-Corrosion Metal Paints
- Essential for gates, railings, trims, gutters
- Includes rust inhibitors and protective primers
When selecting exterior paint in Hermanus, always check for:
- Built-in UV blockers
- Moisture-resistant technology
- Anti-fungal or anti-mould properties
- “Coastal grade” or “marine approved” product labelling
Preparation & Application Guide for Maximum Durability
Even the best paint will fail if the surface is poorly prepared. Proper prep work extends the lifespan of your coating—especially in coastal conditions.
Step-by-Step Painting Process
- Surface Cleaning
- Wash walls and roofs to remove salt, dirt, algae, and mildew
- Use high-pressure cleaning where safe
- Repair & Sanding
- Fill cracks, patch holes, smooth rough spots
- Remove loose or peeling paint with a scraper or wire brush
- Priming
- Use the correct primer for plaster, brick, wood, or metal
- Rusted metal MUST be primed with anti-corrosion primer
- Apply at Least Two Coats
- Thinner, even coats last longer than one thick layer
- Avoid painting in direct midday sun or during high humidity
- Final Seal (Optional but Recommended)
- Clear sealants are beneficial on stone, wood, and porous surfaces
A properly painted coastal home should last 8–12 years before needing repainting—if the right products and preparation methods are used.
