Preparation for Owl Lava 20 Application

Proper preparation is crucial for the successful application of Owl Lava 20. Here’s what you need to do:

1. Surface Inspection and Cleaning

1. Thoroughly inspect the surface for any damages, cracks, or loose materials.
2. For timber (OSB/Plywood), make sure the surface is clean, dry, and dust free.
3. For refurbishing surfaces (such as Felt, Asphalt, Trocal, PVC, Metal, etc.), clean the surface with a pressure washer or a stiff brush to remove dirt, debris, and any loose particles.
4. Allow the surface to dry completely. Remember, Owl Lava 20 must be applied to a clean and dry surface for optimal results, with a maximum moisture content of 10%.

2. Repairing Damages and Cracks

1. Fill all cracks, gaps, joints or holes using OWL PU Mastic sealant.
2. For larger damages or areas prone to movement, consider using a reinforcement matting in conjunction with Owl Lava 20.

3. Priming Requirements

1. Apply Owl Lava Super Quick Prime to all substrates before applying Owl Lava 20.
2. Allow the primer to dry according to the manufacturer’s instructions.

For a hassle-free application process, consider using the comprehensive Owl Lava 20 repair kits available from Global Coatings, which include all the essential components you’ll need.

Step-by-Step Owl Lava 20 Application Guide

Now that you’re prepared, let’s dive into the application process:

1. Mixing Instructions

1. Open the Owl Lava 20 bucket and stir thoroughly using a mixing paddle attached to an electric drill.
2. If using the Owl Lava 20 Accelerator/Catalyst for coatings heavier than 1.5 kg/m², mix it in now. This will ensure uniform curing with a work time of 25 to 30 minutes.

2. Application Techniques

Owl Lava 20 can be applied using a brush, roller, squeegee or spray equipment. Choose the method that best suits your project:

1. Brush Application: Ideal for small areas and detailed work.
2. Roller Application: Best for large, flat surfaces.
3. Squeegee Application: Recommended for a seamless finish.

Regardless of the method, ensure even coverage and watch for any missed spots.

3. Applying Multiple Coats

For optimal protection and longevity, apply Owl Lava 20 in multiple coats:

1. For a 10-year life expectancy, apply a single coat at a rate of 1.8 kg/m².
2. For a 20-year life expectancy, apply two coats at 1.5 kg/m² each.
3. On porous substrates like concrete or felt, apply a minimum of 3 kg/m².
4. Allow each coat to dry for 6-8 hours at 20°C before applying the next coat.
5. Apply subsequent coats perpendicular to the previous coat for even coverage.

4. Reinforcement and Spot Repairs

For any joints, overlaps or areas prone to movement expansion and contraction:

1. Apply a first coat of Owl Lava 20.
2. While still wet, embed a reinforcement fabric into the coating.
3. Apply a second coat of Owl Lava 20 over the fabric.

For all applications over existing Felt/Asphalt, Trocal, EPDM, failed GRP etc., apply the Lava20 system in conjunction with ChopStrand Matting for full reinforcement (180g or 225g).

Pro Tip: When reinforcing joints, avoid using the Catalyst/Accelerator. This allows for slower curing, giving you more time for joint work (wet on wet application).

Optional Coloured Top Coats

To protect the waterproofing coating and add a splash of colour:

1. Allow the final coat of Owl Lava 20 to cure fully.
2. Apply the chosen Lava 20 coloured top coat (available in dark grey, black, blue, green, brown, and white) according to the manufacturer’s instructions.

Optimizing Owl Lava 20 Performance

To get the best out of your Owl Lava 20 application, consider these factors:

Understanding Coverage Rates and Calculations>

• For a 10-year life expectancy, apply a single coat at 1.8 kg/m².
• For a 20-year life expectancy, apply two coats at 1.5 kg/m² each.
• On porous substrates like concrete or felt, apply a minimum of 3 kg/m².

To calculate the amount needed, multiply the coverage rate by the surface area in square meters.

Ideal Application Temperature and Weather Conditions

• Apply Owl Lava 20 when the ambient temperature is between 5°C and 35°C.
• The product can cure in temperatures as low as 0°C (Catalyst/Accelerator required).
• Relative humidity should be below 85% for optimal curing.

Drying Time and Curing Process

• Owl Lava 20 is typically touch-dry within 45 minutes at 20°C.
• Allow 6-8 hours between coats at 20°C.
• Full cure is achieved after 7 days.

Safety and Troubleshooting

Personal Protective Equipment (PPE)

Always wear appropriate PPE when working with Owl Lava 20:

• Protective gloves
• Safety goggles
• Respiratory protection (when spraying)
• Protective clothing

Ventilation Requirements

Ensure adequate ventilation when applying Owl Lava 20, especially in enclosed spaces.

Common Issues and Solutions

1. Bubbling or Blistering
   • Cause: Application of more than 1.5kg/m² at one time without the use of Catalyst/Accelerator.
   • Solution: Once Lava 20 has cured, address the blisters by sanding the surface and applying more Lava 20 for smaller blisters. For larger blisters that require cutting, fill the gap with OWL PU Mastic before applying another coat of Lava 20 over the repaired area.
2. Poor Adhesion
   • Cause: Inadequate surface preparation or priming.
   • Solution: Remove the existing coating, clean and dry the surface, prime the area, and then reapply the Lava 20 coating.
3. Uneven Application
   • Cause: Inconsistent application technique
   • Solution: Sand the uneven surface and apply Owl Lava 20 to level it.
4. Slow Drying or Curing
   • Cause: Low temperature or high humidity
   • Solution: Apply in suitable weather conditions and/or use the Accelerator/Catalyst. Allow for extra time until the coating is cured.

Maintenance and Long-Term Care

To ensure the longevity of your Owl Lava 20 waterproofing system:

Cleaning the Owl Lava 20 Surface

• Regularly remove debris and dirt using a soft brush or low-pressure water.
• Avoid harsh chemicals that could damage the coating.

Periodic Inspections

• Conduct visual inspections at least twice a year.
• Pay special attention to joints, seams, and areas of high foot traffic.

Repairing Damages

For minor damages:

1. Clean the damaged area thoroughly.
2. Apply a small amount of Owl Fast Primer.
3. Apply Owl Lava 20 over the damage, feathering the edges.
4. Allow it to cure fully.

Reapplication Guidelines

• For optimal protection, consider reapplying Owl Lava 20 every 10-20 years, depending on the initial application thickness and environmental conditions.
