SAFEBLOCK SEAL is a blend of high performance polyurethanes and acrylic resins formulated for sealing concrete surfaces, blocks and paving.
It forms a film after evaporation of water. The film is clear and highly resilient. SAFEBLOCK SEAL penetrates and seals paving surfaces to protect against the effects of weathering.
• Penetrates and seals masonry surfaces to protect against the effects of weathering.
• Dries to a clear transparent film that resists yellowing under exterior or ultraviolet exposure.
• Gives an alternative to solvent based materials where fumes may be objectionable, undesirable, or noncompliant.
• Suitable for use on renders and block work
• Reduces or eliminates efflorescence
• Complies with SI 2773 Environmental Protection. Sub Category c; Exterior Walls of Mineral Substrate with a maximum VOC of 30g/l
Surface Preparation:
The surface should be clean and free of mold, mildew or other plant growth. Remove any other materials that may prevent adhesion of the SAFEBLOCK SEAL. Avoid spraying onto windows, doors or surrounds by masking where necessary. Surfaces need not be dry but excessive dampness will reduce penetration.
Mixing:
SAFEBLOCK SEAL should be used directly from the container.
Application:
Apply at a uniform coverage by spray, brush or roller. SAFEBLOCK SEAL may be sprayed with a hand held “pump-up” sprayer or with an airless industrial sprayer. If roller applied, use a short 8-10mm nap sleeve.
Sealing:
Generally a second coat will be required, apply within 24 hours.
Cleaning:
Immediately after spraying, clean line and nozzle thoroughly with water. Brushes and rollers can also be cleaned with water.
Limitations:
Do not use in rain or if rain is expected in next 4 hours. Do not use in freezing temperatures. Suitable for most general applications but should not be used where persistent moisture is present. Where bricks have softened or pointing is friable, repairs should be carried out before
application of SAFEBLOCK SEAL
Technical Information:
The following results were developed under laboratory conditions for a 0.1mm wet film.
• Drying Time* at 20°C, 60% RH 1-2 hours
• Recoat Time** 3-4 hours but <24 hrs
• VOC Content 30g/l
**Where a second coat is to be applied, application must be within 24 hours to ensure proper inter-coat adhesion.
• Adhesion to clay bricks ASTM D-4541 excellent Weatherometer testing
• Ultraviolet resistance good
• Chalk resistance no chalking
• Check/peel resistance no deterioration
• Low surface or air temperatures and/or high relative humidity will extend drying times.
Sealing and Dustproofing Masonry: First Coat 3-5 m2/litre Optional Second coat: 5-7 m2/litre. *Coverage rates assume dense bricks, and will vary from the above rates depending on surface porosity and texture.
AVOID EXCESSIVE BUILD-UP. THICKER APPLICATIONS MAY LEAD TO DISCOLOURATION AND IMPROPER SEALER PERFORMANCE.
Keep containers sealed. Store in dry conditions at room temperature and away from direct heat. Protect from frost. When stored correctly in unopened container storage stability is 1 year. Stir or mix thoroughly if stored for more than 21 days.
1 year when stored as per the instructions above.
