- Surface Preparation
- Ensure all areas are clean, dry and free from dust, dirt, corrosion and general surface contamination.
- All oils, grease, etc. should be removed with suitable degreasing solution.
- Always prime the substrate see PMMA-Based Universal Primer.
- Advice on Application
- Due to exothermic reaction with mixing process, please ensure the product is mixed in a steel container.
- First stir the PMMA-Based Waterproofing liquid Coating with a paddle mixer thoroughly.
- Then add the PMMA Catalyst while stirring the waterproofing liquid coating at a slow speed.
- Mix for 1 - 2 minutes.
- You must not dose less than the given quantity of PMMA Catalyst, as this will jeopardize the curing process.
- You must also avoid overdosing the PMMA Catalyst, as this can likewise lead to serious curing problems.
- The material must be applied as soon as the PMMA Catalyst has finished dissolving in the resin components.
- Equipment Cleaning
- If work is interrupted or when it is completed, clean the tools thoroughly with cleaning agent within the pot life of the material.
- This can be done with a brush.
- Do not use the tools again until the cleaning agent has evaporated fully.
- Simply immersing the tools in the cleaning agent will not prevent the material from hardening.
- Practical Coverage
Practical coverage can vary considerably depending on method of application, surface roughness, weather conditions and complexity of the structure.
- Theoretical Coverage
1.3 kg/m² per mm thickness.
