ARMADILLO D sealer is a proprietary blend of silica (Si) polymers which penetrate concrete surfaces providing an increase in abrasion resistance and a reduction in the surface absorption of liquids. The Silicate compounds present in ARMADILLO D each play a unique role in densifying and sealing concrete. The silicates in ARMADILLO D chemically react with calcium hydroxide (also known as portlandite) in the surface to produce calcium silicate hydrate (CSH) – the primary strength-providing portion of concrete paste. Portlandite is a soft, porous mineral that is subject to carbonation and chemical attack, so replacing it with the much stronger CSH is a major benefit of ARMADILLO D. The ultimate result is a concrete floor that is harder and exceptionally dense which equals long-lasting protection and durability. ARMADILLO D is water based. It generally dries tack free in 2 to 4 hours at 21C @ 50% RH.
PRIMARY APPLICATIONS •Dust-proofing •Repair of rain damaged surfaces •Repair/reinstatement of weak mortar •Repair/restoration old carbonated concrete •Interior / exterior •Warehouse /Commercial floors •Manufacturing plants •Residential garages and basements •Reduces porosity, dustproof and increases hardness of the concrete surface •Combines with the concrete becoming part of the matrix and lasts the lifetime of the substrate. •Complies with GREEN STAR- OFFICE DESIGN V3 IEQ-13 •Resists penetration of oil and many chemicals •Reduces the ingress of carbon dioxide and resulting carbonation (degradation of the substrate) •Minimizes tyre marks and enables them to be more easily removed •Equipment can be cleaned with water •Can be applied to fresh, new or existing concrete •Will not blush •After Trades compatible ( can be over tiled or line marked #) •Compatible with bond breakers for tilt-up projects. •‘Cure’ * and seal capability
Apply ARMADILLO D at the suggested rate (5m2/L) by broom or low-pressure sprayer. Keep the entire surface of the concrete wet with ARMADILLO D for a minimum of 30 minutes. The material may be broomed around on the surface to ensure good coverage. As the ARMADILLO D begins to thicken and gel (but no more than 60 minutes after initial application) broom and squeegee the excess material on to the adjacent floor area next to be treated. If necessary, lightly sprinkle water on the surface to aid in removal. Continue until the entire floor has been treated. Vacuum or squeegee to remove any excess material.
Surface Preparation-The concrete surface must be clean, dry and free of any contaminant or coating.
For best results on large areas ARMADILLO D should be applied and scrubbed in using mechanical scrubbers. Select the section of floor for the initial application. Apply ARMADILLO D to the concrete surface in a continuous operation at a rate of approximately 5m2 /litre on steel trowelled surfaces. The liquid should be scrubbed into the surface with a mechanical scrubber.
For smaller areas and along the perimeter of the slab, application by watering-can then working in with a bristle broom is appropriate. The scrubbing action assists ARMADILLO D in penetrating the surface. Keep the surface wet with ARMADILLO D at all times during the application process and on porous slabs, several repeated applications may be necessary to achieve an excess on the surface.
When the product thickens (but no more than 60 minutes after initial application) the surface should then be squeegeed on to the adjacent floor area next to be treated. Continue until the entire floor area has been treated. Vacuum or squeegee to remove all excess liquid. The surface may be flushed with water to aid in removal of the excess material.
