Stamped Concrete System Guide by Par chem Constr uction Suppl i es Stamped Concrete System Guide Stamped Concrete shape has shallow surface impressions to impart surface definition. Stamping is a system of adding an impressioned pattern, a two toned colour effect and texture to the surface of a newly poured concrete pavement. You can create a realistic effect of slate, stone and wood. The Release agent pigments the deepest points to highlight the pattern Suitable Uses Residential Setting - driveways, patio’s, paths and decorative kerbing. Caution: Due to the smooth surface, stamped is not suitable for sloping pavements, pool areas or for regular use by the elderly or disabled persons. Do not consider this finish on surfaces which require a slip resistant surface. Specifying a cove finish will assist but may not solve the slip issue. Distinctive Features and Benefits igh class decorative appeal H Wide range of stamps patterns and colours Two-toned appearance by combining colours Release Agent is darker than the base colour hardener Smooth high gloss surface or Cove finish to add some slip resistance New concrete application only Hardened surface of up to 47 MPa which in turn provides durability and increased wear Components Colour Hardener Colour Hardener: is a dry shake, surface colour system used as the base or main colour. It provides a vibrant depth of colour with the added benefit of strengthening the concrete surface up to 47 MPa. A variety of finishes can be achieved from smooth to rough texture. Some level of slip resistance can be achieved if specified. (Refer to finishes) Coloured Release Agent Release agents have a dual function. 1. When impressioned into the concrete, the Release Agent colours or stains the deeper impressioned areas creating the two toned look. 2. A water resistant wax coating which stops the stamp mats from sticking to the concrete Stamped Impression Mats Rubber or urethane matts which are moulded into shapes and impressioned with a surface texture. The set of mats fit together like a jigsaw puzzle allowing the contractor to impression a continuous pattern onto the pavement. The mats consist of a deep impression which outlines a shape such as rocks, pavers and timber boards. Each 2 Seamless matt is the only matt which does not consist of a shape, rather provides a large area of shallow impression creating a sandstone look. Seal Coat Sealer is added to achieve the high gloss look of Stamped Concrete. Please note, sealing a smooth surface will increase the risk of slipping. For a high gloss finish use M20 Urethane Sealer. For a semi -gloss use Parchem’s Acrylic Sealer. To achieve a natural look use Lustreseal Matt Finish Sealer. Sealing aids cleanability by helping to reduce the level of dirt ingress and helps enhance the decorative appearance. Whilst not chemical resistant, sealer provides protection from contaminants such as petrol and oil. Design Tip Stamped Concrete System Guide Installation / Application STEP 1: Preparation & Protection STEP 5: Apply Release Agent STEP 2: Place slab as per AS 3727 STEP 6: Stamp STEP 3: Apply Colour Hardener STEP 7: Three days curing to allow the Release Agent to take effect STEP 4: Apply surface texture STEP 8: Seal the surface adding slip resistant additive *If powdered Release Agent is used, an additional step is required to wash and remove the Release Agent from the surface. 3 Stamped Concrete System Guide Surface Finishes Limitations Slip and skid resistance is largely determines by the final finish. Slip resistant surfaces are easy to achieve with Colour Hardener due to the sands in the mix and application method. The following finishes are widely accepted within the construction and concrete industries: Smooth Trowel Timing is crucial to the success of stamp jobs. Powdered R/A will contaminate the water ways. Sand traps must be put on the drains to prevent the Release Agent entering the storm water. All Release Agent must be washed off as the sealer will not bond Licenced Contractor must be experienced in decorative concrete applications – not a DIY application Weather Freeze Thaw – adjust concrete mix accordingly Mess if preventative steps are not taken Suitability of this product must ultimately be determined by the contractor This document only discusses the decorative finish on the surface. Slab design must include all structural elements such as sound supporting sub base, reinforcement, and compaction and correct jointing required producing structural integrity within the slab itself. This system must be applied in accordance with product application manual and Technical Data. Application methods supplied in this document are a summary only. Cove Finished Stamp Relevant Standards & Documents of Interest Maintenance Regular maintenance and cleaning of the surface will prevent staining and keep the pavement looking at its best. Reseal every 12 – 18 months depending on the in service conditions. Please contact a Parchem Branch for instructions and further advice.
