Preparation:
Surfaces should be clean from dust, debris, dirt, oils, grease, curing compounds, other coatings, efflorescence and laitance before applying. If strong acidic or caustic cleaners are used, neutralise the surface with a diluted solution of PCA Stone Degreaser™, thoroughly and completely wash/rinse to remove any residues.
Application:
- Ensure the surface is clean and dry.
- Any existing stains must be removed prior to sealant application.
- Cover surfaces not intended to be treated.
- Apply an even first coat using a low-pressure sprayer or a lamb’s wool applicator.
- Allow sealer to completely penetrate prior to applying a second coat (if needed) and remove any excess sealer.
- If a second coat is required on porous surfaces, repeat steps 4 and 5.
- After final application, thoroughly wipe all excess sealer with clean and absorbent towels.
- A full cure is achieved in 24 – 72 hours. Foot traffic can resume in 8 hours, driving in 24 hours.
- It is important that no water comes into contact with newly sealed surfaces for at least 24 hours after application.
- Clean tools used during application with water.
Coverage:
Application rate depends on porosity of the tile or paver, temperature and method of application and ranges between 4 – 15 SQMs per litre. USE AS IS, DO NOT DILUTE.
Maintenance:
Use PCA Stone Soap™ for daily/weekly cleaning. Use PCA Stone Degreaser™ for stain spot cleaning and periodical cleans.
