Substrate:
Substrates must be sound, clean, dry, free from frost, dust efflorescence and not water repellent.
Prepare smooth concrete or very low suction surfaces with a suitable Baumit contact mortar (e.g. Baumit HM 50).
Prepare mixed masonry substrates and natural stone with a spatterdash coating.
High suction substrates should be dampened with water using a mist sprayer. Do not saturate aircrete substrates.
Preparation and levelling coatings must be fully cured, well keyed and compatible with the plaster system.
Refer to Baumit technical support for further advice regarding substrate preparation.
Application:
Mixing: Baumit Klima RK 38 can be mixed with clean water in a tub to a lump free, creamy consistency with an electric hand mixer. Automated continuous horizontal mixers may also be used. For small areas the mixed plaster can be manually applied. For larger areas the fresh plaster can be fed into a mortar pump for spray application. Alternatively, mortar mixing pumps provide an all-in-one mixing and spraying solution.
Basecoat plaster: The plaster is applied onto the substrate to the required thickness in one or two passes (fresh-infresh) depending on the degree of suction from the substrate and ruled off with a straight edge, filling in undulations to produce a flat and even plaster layer.
On hardening the surface is finely floated or finely scraped in preparation for receiving the topcoat. The drying times (1 day/mm thickness) must be observed.
A maximum plaster thickness of 20 mm may be applied in a single application. Where necessary, greater thicknesses must be built up in multiple coats of at least 10 mm in thickness. Upon setting the surface of each additional coat is horizontally keyed with a plasterers comb to receive the following coat. Drying times between each coat (1 day/mm thickness) must be observed.
Topcoat plaster: Baumit Klima RK 38 as a topcoat plaster is applied onto the basecoat and smoothed out flat with a trowel or spatula to a thickness of 3 mm. Shortly afterwards the surface is lightly rubbed over with a fine sponge float in tight circular motions to produce a fine, plain finish. A paint finish may be applied if required.
Baumit Kalkputz Klima Glätt W (lime skim finishing plaster) or Baumit decorative topcoat plasters are also suitable for application onto a basecoat of Baumit Klima RK 38
