Elastomeric, pigmented acrylic, anti-chloride ion, and carbonation protective and decorative coating for concrete and masonry
Vetotop AC441 is a single component penetrating silane-siloxane primer and a single component elastomeric pigmented coating, ready for immediate site use. Vetoprime AP443 is supplied as a clear liquid and is based on an acrylic resin and a silane-siloxane dissolved in a penetrating organic carrier. Vetoprime AP443 is reactive and capable of producing a chemically bound hydrophobic barrier, thus inhibiting the passage of water and water-borne contaminants. Vetotop AC441 is a crack-accommodating, water-based protective coating based on a special acrylic polymer, providing outstanding elongation and recovery, resistance to aggressive elements, UV light, and rain.
Vetotop AC441 is supplied in 2a 0Kg Container. Consumption: 4m2/kg @200 mic WFT.
Vetoprime AP443 is supplied in a 5 Liter Container. Consumption: 0.4Liter/m2
Stated consumption data are for general guidance. Actual consumption depends on the nature of the substrate, method of application, and wastage.
The original sealed Containers of Vetotop AC441 and Vetoprime AP443 have a shelf life of 12 months, provided it is stored clear of ground in a dry and shaded place below 35ºC.
Vetotop AC441 should generally be applied in two coats to achieve a total dry film thickness of not less than 200 microns to accommodate substrate cracking up to 2 mm and cyclic movement up to 0.3 mm. It is possible to achieve the total dry film thickness in one coat; however, this depends on the substrate type, and the finish required. Trials are recommended before the full application to ensure the finish meets the client’s requirements. Vetotop AC441 must be applied to the substrate at the coverage rates suggested achieving the correct protective properties.
Firstly, apply Vetoprime AP443 in one or more coats until achieving the recommended application rate of 0.4 liters per square meter. This is best accomplished by using portable spray equipment. Conduct a uniform surface appearance (sheen).
Allow the primer to dry for a minimum of two hours (at 20°C) before overcoated with Vetotop AC441.
To obtain the Vetotop AC441 system’s protective properties, the correct rates of application and overcoating times must be observed.
Apply Vetotop AC441 in two coats. The first coat can be thinned with clean water depending on the substrate. The recoat time for the second coat is two hours. If necessary, apply a third coat to achieve a hiding power.
No gaps or ‘raw edges’ must appear in the finished coating. Take special care to provide an unbroken layer at the external corners and similarly exposed protrusions.
Vetotop AC441 may be applied by the use of suitable brushes, rollers, or airless spray equipment.
Remove Vetotop AC441 from tools and equipment with clean water immediately after use.
All surfaces should be dry and free from contamination, traces of mold-release oils, and curing compounds. This is best achieved by lightly grit-blasting the surface. Where moss, algae, or similar growths have occurred, treatment with a proprietary biocide should be carried out after the grit-blasting process.
Where required to apply over existing sound coatings, conduct trials to ensure compatibility and retention of the bond between the underlying and substrate layer. It is essential to produce an unbroken coating of Vetotop AC441. Fill surfaces that contain blow-holes or pitting areas using Vetorep CR523, a cementitious fairing coat. Level rougher substrates by using a cementitious product from Saveto Concrete Repair Range.
Vetotop AC441 should not come in contact with the skin and eyes or be swallowed. In case of skin contact, rinse with plenty of clean water, cleanse with soap and water.
In contact with the eyes, rinse immediately with plenty of clean water and seek medical advice.
If swallowed, seek medical attention immediately, do not induce vomiting.
Vetotop AC441 is non-flammable.
