    Suitable Substrates

    The substrate must be sound/stable, dry, and clean and free from all substances that may prevent adhesion. In Germany: Follow VOB, part C, DIN 18 363, section 3.

    Depending on the substrate and its condition, a suitable priming coat must be applied prior to filler/surfacer application. Glossy, stable existing coatings must be roughened beforehand.

    Substrate preparation:

    Plasters of mortar group PII and PIII/compressive strength according to DIN EN 998-1 with min. 2 N/mm2: Solid, normally absorbent plasters without pretreatment. On coarsely porous, sanding, absorbent renders one priming coat with CapaSol RapidGrund or CapaSol Konzentrat.

    Gypsum plasters of mortar group PIV/compressive strength according to DIN EN 13279 with min. 2 N/mm2: One prime coat with HaftGrund EG. (Grind gypsum plasters with sintered skin, remove dust, prime with Dupa-Putzfestiger).

    Gypsum boards: Prime absorbent boards with CapaSol RapidGrund or CapaSol Konzentrat in appropriate dilution. On highly compacted, smooth boards apply a adhesion promoting priming coat with HaftGrund EG.

    Gypsum boards (plasterboard):
    Sand off high filler burrs. Strengthen soft gypsum filler areas with Dupa Putzfestiger to strengthen. For boards with water-soluble, discoloring ingredients, apply a priming coat of Caparol AquaSperrgrund. 

    Concrete: remove existing release agent residues as well as chalking, sanding substances.

    Aerated concrete:
    Apply one priming coat of Capaplex, diluted 1 : 3 with water.

    Sand-lime brick and exposed brickwork: Coat without pretreatment.

    Sound coatings:
    Recoat matt, weakly absorbent coatings directly. Roughen glossy surfaces and paint coatings. One priming coat of HaftGrund EG

    Distemper paint:
    Wash off. Apply one priming coat of Dupa-Putzfestiger

    Paper wall coverings: Remove without residue. Wash off paste and waste paper. Prime with Dupa-Putzfestiger.


    Mold-infested surfaces: Remove mold or fungal infestation by wet cleaning. Wash thoroughly with Capatox or treat with FungiGrund and allow to dry well.

    Surfaces with nicotine, water, soot or grease stains: Wash off nicotine stains and soot or grease stains with water, adding a grease-dissolving household detergent, and allow to dry well. Clean dried water stains dry by brushing. After application, surfaces with migrated stains are to be coated with Caparol AquaSperrgrund.


    Chipping, joints and defects: Filling the recess with Füllspachtel P.

    Note Q2/Q3 Filling / thin layers of gypsum < 0.5 mm: When using gypsum-containing, hydraulically setting filling compounds in quality grade Q2/Q3, a transparent water-based primer is recommended. Please refer to the Maler & Lackierer data sheet no. 2 -9/2020 "Adhesion problems of coatings on filled gypsum (cardboard) boards" of German Bundesverband Farbe, Gestaltung, Bautenschutz - Bundesausschuss Farbe und Sachwertschutz. As an alternative to gypsum-based Q3 putties, putties containing pasty fillers have proven their worth.



    Method of Application

    Manual Smoothing:
    Stir well before use and apply with a stainless steel trowel.

    Suitable spraying equipment:
    The filler can be applied with plaster conveyors and with powerful airless equipment. The conveying distance of the product depends on the performance of the airless equipment and must be obtained from the equipment manufacturers of the equipment. Remove all filters from airless guns. As an airless gun, spray guns with a higher flow rate recommended by the respective manufacturer should be used for fillers. Depending on the capacity of the airless unit, it is possible that at temperatures below +10 °C due to slight changes in the viscosity of the filler. Restrictions in conveying may occur. For these devices, a material temperature of +10 °C must be ensured.

    Spray application:

    Coating is efficient and economical, especially when used in conjunction with high-performance spray equipment of wall and ceiling surfaces.

    Working procedure:

    Supply the unit with putty. We recommend using a material hopper to be used. Full-surface, saturated spraying with filler, undiluted, and immediate smoothing with a suitable steel trowel. The filler can be sanded after thorough drying. Sanding grids such as Abranet from Mirka or GranatNet from Festool with a grit size of 120 enable a more effective working performance.

    Suitable spraying equipment:

    The filler can be applied with plaster conveyors and with powerful airless equipment. As airless gun, spray guns recommended by the respective manufacturer should be used. These guns have a higher flow rate and make it considerably easier to apply the filler. In the case of buckets, stirring with a stirrer is recommended.

     Device-dependent spray coke necessary

    Spray application with mottling:
    The coating and mottling of wall and ceiling surfaces is rational and economical of e.g. precast concrete elements, smoothly formed in-situ concrete, and aerated concrete as well as gypsum building boards and gypsum boards in the thin plaster method with powerful spraying equipment.

    Working procedure:

    Connecting the sprayer to the container with the connection tap available from us for this purpose and an appropriate connection hose. Full-surface, saturated spray application with spatula, undiluted and immediate flat smoothing with a suitable steel trowel.
    After drying, the filler can be felt by wetting or dry sanded. After good drying the levelled surface, a mottling application can be made in fine to coarse structure. The texture can be varied depending on the degree of dilution and related nozzle width. The mottle application can be left untreated on ceiling surfaces. For substrates that have not yet reached their moisture content, partial light/dark variations may be perceptible after speckle application. Dark variations may be noticeable. In this case, a leveling coat is recommended.

    Work team and performance:

    A spray crew consists of a team of 2-3 craftsmen. One of the team applies the material with the sprayer in a constant layer thickness, 2 workers pull off the applied material evenly and then smooth the surface. material evenly and then smooth the surface.

    Special processing instructions for flat filling and mottling:

    For larger rooms, first smooth the ceiling before spraying the wall surfaces. In In this case, however, the upper part of the wall surfaces (the so-called head) should be sprayed and from the floor should also be sprayed and smoothed. Then the lower part of the wall surfaces is sprayed and smoothed as well.
    If only the ceiling surface is to be processed, it is advisable to first spray an edge from the wall surfaces and then spray the surface. All corners should be smoothed and slightly after smoothing and slight drying with a wet radiator brush. Remove bubbles after slight drying by smoothing again, repeat if necessary. Existing nests by hand.

    After good drying of the filler, rust penetrations with a suitable anti-corrosion primer, e.g. Capalac AquaMulti Pimer, applied by stippling. Subsequently, apply a coat of paint.

    Insertion of reinforcing fleece:

    Observe the specifications in the Technical Information on Capaver AkkordVlies G45 SP.




    Surface Coating System

    Recoatability:

    Paint / plastic masses (plasters):
    After thorough drying, smoothed surfaces can be coated with all suitable Caparol dispersion and latex paints or Capacryl acrylic paints, latex paints or Capacryl acrylic paints. Before further treatment with Sylitol® interior paints, Sylitol® renders, a priming coat with Caparol Haftgrund EG, CapaSol Konzentrat in appropriate dilution or CapaSol RapidGrund is recommended.  For subsequent dispersion renders, a priming coat with Putzgrund 610 is required.

    Glas- cellulose polyester wall coverings for subsequent coating:
    Smoothed surfaces can be recoated with glass fabric or cellulose polyester wall coverings after thorough drying. For this purpose, a priming coat of Caparol-Haftgrund EG is required.

    Surface-finished, strongly diffusion-blocking or diffusion-tight wall coverings:

    At least Akkordspachtel KF must be used. In addition, the technical data of the wall covering manufacturer must also be observed.

    Consumption

    Spray application:
    Approx. 1600 g/m2 per mm of coating thickness.

    Spatter technique:
    Approx. 400 - 700 g/m2, depending on the desired texture.

    Application Conditions

    Lower Temperature Limit for Application and Drying:
    +5° C for substrate and ambient air.
    Temperature of product during application must be > + 10° C.

    Drying/Drying Time

    Approx. 12 - 48 hours, depending on building moisture, temperature and coating thickness.

    Tool Cleaning

    Clean tools/equipment immediately after use with clean water.

    Note

    Caparol-Akkordspachtel SF "plus" is unsuitable for damp locations. Slight colour differences may occur due to the use of natural fillers. If the surface will remain unpainted after spray application (spatter technique), then it is suggested to use material of same batch for filling and spray application.

    Abrasion can occur if using plaster conveyor equipment, particularly when new conveyor screws and tubes are used. Please follow the instructions given by the relative manufacturers.

    For spray application on wall areas in spatter technique, recoating with Caparol emulsion paints is advisable to obtain a higher resistance.

    Fine blistering may appear on compact, low absorbent substrates. This can be removed by repeated smoothing after having allowed to flash off for a short time. The proper timing for re-smoothing depends on temperature and air moisture on site. When small blisters recur, even after re-smoothing, the smoothing process which obviously had been made too early must be repeated.

    On roughly textured substrates an additional smoothing process may be necessary.

    Reworking gypsum filling compounds may lead to swelling, blistering and flaking due to long lasting moisture exposure. Provide for quick drying by sufficient ventilation and temperature. In Germany: Follow Data Sheet No. 2 "Verspachtelung von Gipsplatten" (Trowel Application on Plasterboards) issued by the German Association of Gypsum and Plasterboard Industry.
