Technical Information
Preparation:
Surfaces should be clean from dust, dirt, oils, grease, curing compounds, efflorescence and laitance before applying PCA PreSeal™. If strong acidic or caustic cleaners are used for floor preparation, 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 penetrate the surface for 5 minutes.
- If a second coat is required on porous surfaces, please repeat step 4 and 5 while the first coat is still wet. (wet on wet application)
- After final application, thoroughly wipe all excess sealer with clean and absorbent towels.
- Should a product residue appear (white), agitate the surface with a white nylon scrubbing pad to loosen the residue.
- 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 6 – 15 sqms per litre per coat. Please note that dip sealing will require more product as all 6 sides of the tile or paver are being sealed.
Maintenance:
For regular cleaning use PCA Stone Soap™. For heavy duty cleaning use PCA Stone Degreaser™.
