Before You Start: Essential Preparation

Materials and Tools You'll Need

Paint and Supplies:

• Coo-Var × Rock City Climbing Wall Paint (calculate coverage: approximately 6-8m² per litre)
• Paint stirring stick or paddle mixer attachment
• Paint tray or scuttle
• Measuring container (if thinning is needed)

Application Tools:

• Medium-pile paint roller (9" or 12" width)
• Roller frame and extension pole
• 2-3" angled brush for edges and corners
• Spare roller sleeves

Preparation Equipment:

• Sandpaper (120-180 grit)
• Sanding block or electric sander
• Vacuum cleaner or brush
• Clean cloths or tack cloth
• Dust sheets or plastic sheeting
• Masking tape
• Cleaning solution (sugar soap or mild detergent)

Safety Equipment:

• Dust mask or respirator
• Safety glasses
• Gloves
• Ventilation (open windows or fans)

Step 1: Surface Preparation (Critical for Success)

Proper surface preparation is the foundation of a successful climbing wall paint job. Skipping or rushing this stage will compromise adhesion, texture, and durability.

For New Plywood Surfaces

1. Inspect the plywood: Check for defects, splinters, or damage. Replace any damaged sheets.
2. Sand the surface: Use 120-180 grit sandpaper to smooth the plywood, removing any rough patches or raised grain. Pay special attention to edges and joints.
3. Fill gaps and holes: Use wood filler for any gaps between sheets or around T-nut holes. Sand smooth once dry.
4. Remove all dust: Vacuum thoroughly, then wipe down with a slightly damp cloth or tack cloth. The surface must be completely dust-free.
5. Check for moisture: Ensure plywood is completely dry. Moisture content should be below 12%.
6. Allow to acclimatise: If plywood has been stored in cold or damp conditions, allow it to reach room temperature and dry completely.

For Existing Painted Surfaces (Repainting)

1. Remove climbing holds: Take down all holds and store safely with their bolts.
2. Clean thoroughly: Wash the entire surface with sugar soap or mild detergent solution to remove chalk, dirt, grease, and grime. Rinse with clean water.
3. Allow to dry completely: Wait at least 24 hours for the surface to dry thoroughly.
4. Sand the surface: Lightly sand with 180 grit sandpaper to create a key for the new paint. You don't need to remove all old paint, just roughen the surface.
5. Repair damage: Fill any chips, cracks, or damaged areas with appropriate filler. Sand smooth once dry.
6. Remove dust: Vacuum and wipe down thoroughly to remove all sanding dust.
7. Check adhesion: If old paint is flaking or peeling badly, it may need complete removal before repainting.

Environmental Conditions

Ensure optimal painting conditions:

• Temperature: 10-25°C is ideal. Avoid painting in very cold or hot conditions.
• Humidity: Low to moderate humidity. Avoid painting on very humid or damp days.
• Ventilation: Ensure good air circulation, but avoid strong draughts that can cause uneven drying.
• Lighting: Good lighting helps you see coverage and avoid missed areas.

Step 2: Protect Surrounding Areas

1. Cover the floor: Lay dust sheets or plastic sheeting to protect flooring and crash mats.
2. Mask edges: Use masking tape to protect door frames, skirting boards, or adjacent walls.
3. Protect fixtures: Cover any light fittings, switches, or features you don't want painted.
4. Ensure ventilation: Open windows or set up fans for air circulation.

Step 3: Prepare the Paint (Crucial Step)

Proper paint preparation is essential for achieving the correct texture and performance.

1. Check the paint: Ensure you have the correct product and sufficient quantity for your project.
2. Stir thoroughly: This is critical! The textured additives in climbing wall paint settle at the bottom of the tin. Stir vigorously for at least 2-3 minutes using a stirring stick or paddle mixer attachment. Scrape the bottom and sides to ensure all settled material is mixed in.
3. Check consistency: The paint should be smooth and uniform with no lumps or separation. Continue stirring if needed.
4. Avoid over-thinning: Coo-Var × Rock City Climbing Wall Paint is ready to use. Only thin if absolutely necessary (maximum 5% water), as this can reduce texture effectiveness.
5. Pour into tray: Pour enough paint for your immediate needs into a paint tray or scuttle.
6. Keep stirring: Stir the paint periodically during application, especially if working for extended periods, to maintain consistent texture distribution.

Step 4: Apply the First Coat

Application Technique

1. Start at the top: Begin painting from the top of the wall and work downwards to avoid drips on completed areas.
2. Load the roller: Dip the roller in paint and roll on the tray to distribute evenly. Don't overload—the roller should be well-coated but not dripping.
3. Apply in sections: Work in manageable sections (approximately 1m²) to maintain a wet edge.
4. Use a W or M pattern: Apply paint in overlapping W or M patterns, then fill in with vertical strokes for even coverage.
5. Maintain consistent pressure: Apply even pressure to ensure uniform thickness and texture.
6. Work systematically: Move across the wall in a logical pattern to avoid missing areas.
7. Blend edges: Overlap slightly into previously painted areas while they're still wet to avoid visible lines.
8. Use a brush for edges: Cut in around edges, corners, and T-nut holes with a brush before rolling adjacent areas.

Coverage and Thickness

• Aim for even coverage without applying too thick or too thin
• Typical coverage: 6-8m² per litre (varies with surface porosity)
• Don't try to achieve full coverage in one coat—two coats are recommended
• Avoid runs, drips, or pooling in corners

Common First Coat Mistakes to Avoid

• Insufficient stirring before application
• Applying too thick (creates uncomfortable roughness)
• Applying too thin (inadequate texture development)
• Working too slowly (creates lap marks as edges dry)
• Overworking the paint (can reduce texture effectiveness)
• Missing areas or uneven coverage

Step 5: Drying Time Between Coats

Proper drying between coats is essential for optimal results:

• Touch dry: Typically 2-4 hours depending on temperature and humidity
• Recoat time: Wait at least 4-6 hours before applying the second coat
• Check readiness: The surface should be dry to touch and not tacky
• Don't rush: Applying the second coat too soon can compromise texture and adhesion
• Maintain conditions: Keep temperature and ventilation consistent during drying

During the drying period:

• Keep the area well-ventilated
• Maintain consistent temperature
• Protect from dust and debris
• Don't touch or test the surface
• Clean your tools ready for the second coat

Step 6: Apply the Second Coat

The second coat is crucial for achieving optimal texture and durability.

1. Inspect the first coat: Check for any missed areas, thin spots, or imperfections.
2. Stir the paint again: Just as thoroughly as before—texture additives settle quickly.
3. Apply using the same technique: Follow the same systematic approach as the first coat.
4. Ensure full coverage: The second coat should provide complete, even coverage.
5. Pay attention to high-contact areas: Areas where hands and feet frequently contact may benefit from slightly heavier coverage.
6. Maintain consistency: Keep application thickness uniform across the entire surface.
7. Final inspection: Check for any missed spots or uneven areas while the paint is still wet.

Step 7: Curing and Final Preparation

Curing Time

Allow proper curing time before use:

• Touch dry: 4-6 hours
• Light use: 24 hours minimum
• Full cure: 48-72 hours for optimal performance
• Heavy use: Wait at least 48 hours before intensive climbing

During the Curing Period

• Maintain good ventilation
• Keep temperature consistent (avoid extreme cold or heat)
• Protect from dust, moisture, and damage
• Don't attach holds or climb on the surface
• Allow the texture to fully develop and harden

Final Steps

1. Remove masking tape: Carefully remove tape while paint is still slightly soft (within 1-2 hours of final coat) to avoid peeling.
2. Clean up: Clean all tools immediately with water. Dispose of waste responsibly.
3. Inspect the finish: Check the entire surface for consistency and quality.
4. Touch up if needed: Address any missed spots or imperfections with a small brush.

Step 8: Installing Holds and Final Setup

Once the paint is fully cured (48+ hours):

1. Clean the surface: Wipe down to remove any dust that settled during curing.
2. Mark hold positions: Plan your route layout and mark T-nut locations.
3. Install holds: Bolt on climbing holds using appropriate bolts and Allen keys.
4. Tighten securely: Ensure all holds are firmly attached but don't overtighten.
5. Test holds: Check each hold is secure before allowing climbing.
6. Position crash mats: Ensure safety matting is properly positioned.
7. Final safety check: Inspect the entire wall, holds, and safety equipment.
