SELF-LEVELLING RENOVATION ROUGH FLOOR (from 5 mm to 30 mm) FOR TERRACOTTA, FLOOR COVERINGS AND WOOD FLOORING
FOR INTERNAL USE
|
| ATLAS TERPLAN R is a self-levelling cement based compound designed for machine or manual rough floors preparation under floor covering made of PVC, carpet, wood flooring, floor panels, terracotta, stone and natural marble. It can be used for repair and modernisation work as well as for new projects. It is recommended in case of levelling of existing substrates, even elevation of rough floor level in the whole room, evening levels of two different floors, and when surface irregularities prevent application of appropriate thickness of an adhesive. Substrates of this self-levelling mass can be made of concrete, cement and anhydrite jointless floors and “difficult surfaces” including vinyl, ceramic, PVC, natural stone or terrazzo substrates. ATLAS TERPLAN can be used for rough floor in the following arrangements: connected with existing substrate (minimum layer thickness - 5 mm), on the separating layer (minimum layer thickness - 20 mm) or for levelling existing surfaces of heating jointless floor. It is suitable only for indoor use. Bed thickness , depending on selected solution, should be 5÷30 mm. |

| TERPLAN R is a dry mixture reinforced with fibre, containing mineral binders, fillers and new generation modifying agents. High elasticity and adhesion to various substrates as well as a wide range of underlayment layer thickness make it a general-purpose product. Easy mass preparation and its operating parameters (excellent fluidity and self-levelling ability) make it convenient to use. It ensures very even substrate characterised by excellent technical and operation parameters, facilitates preparation and increases standard of the final stage of finishing floor work. Optimum selection of setting time and quick increase of strength parameters make rough floor usable in a shorter period of time and ensure preparation of other work. |

|
| The method of preparation depends on the arrangement in which ATLAS TERPLAN R is to be used. In any case, the substrate should be stable and structurally sound. If rough floor is to be connected with substrate, the substrate should be free from anything that may impede adhesion, in particular dust, dirt, lime, oil, fat, wax, bitumen, paint, etc. Mechanically remove loose elements and parts of substrate of poor strength. If necessary, use one or two layers of ATLAS UNI-GRUNT PLUS priming emulsion to reduce substrate’s excessive absorption. Before pouring out the mass, make additional marks on the walls to mark the location of expansion joints in the substrate that will be transferred to the rough floor. Due to the risk of underlayment outflow, the substrate should have a tank-like appearance. The technological fields and possibly floor openings should also be secured, so as to prevent outflow of the mass. This can be achieved by providing adequate profile with adhesive tape or wooden strips, using a bed of dry material as a seal. It is prepared on very weak, absorptive or oily mineral substrates or on other substrates that do not provide appropriate adhesion. The separation layer can be made of 0.2 mm thick polyethylene foil. The insulation should be placed tightly without creases and folded onto the walls (onto the expansion joint strips), at least up to the rough floor height. In case of substrates which are exposed to moisture, a vapour-resistant or anti-moisture insulation placed on the substrate may serve as the separation layer. Rough floor should be reinforced with a glass fibre mesh protected in acrylic bath and fixed to the substrate. In both cases, intermediate expansion joins are not required as the pouring surface of the rough floor does not exceed 20 m2. However, it is required to separate rough floor from walls using ATLAS EXPANSION TAPE or thin strips of foamed polystyrene. |

| In case of mechanical pouring, appropriately set the fixed level of dosed water in a mixing-pumping unit that ensures correct consistency of the mix flowing out from a hose. To check consistency, pour out the mix from a 1 l container onto even non-absorptive substrate (for example - foil). The mix should then form a "patch" of ca. 40 cm in diameter.. In case of manual pouring, prepare it by pouring dry mortar into a container with suitable amount of water (in the ratio of 4.0÷4.5 l of water for 25 kg of container) and mix until homogenous. Do it mechanically; a drill with a mixer is recommended. The mix is ready to use right after mixing. It maintains its properties for 20 minutes. Inappropriate amount of water for mix preparation results in deterioration of strength parameters of the rough floor. |

|
| First, it is necessary to determine the desired level and mark it on the walls and in the area where the mass is to be poured. This can be done e.g. using a level and height bench-marks. ATLAS TERPLAN R may be poured mechanically, using in a mixing-pumping unit that enables continuous flow proportioning of water, but only on surfaces divided into technological fields that enable pouring within 45 minutes. Start pouring from the farthermost wall in relation to the exit. Pour it in the form of approximately 50 cm wide belts parallel to the wall, paying attention not to step on the surface. Connect successive parts of the underlayment in at most 10 minutes. Initially distribute the poured mix using e.g. a smooth float made of metal. Rake up excess of the mix, thus controlling bed thickness. It is also recommended to de-aerate the mix using a wire mesh roller or a brush with hard long horsehair, moving the brush in shaking manner along and across the poured surface. This operation improves the spreading process and helps to obtain a more homogenous surface. Do not dilute the setting material. Protect the poured mix from drying too quickly, direct sunlight, low air humidity and draughts. Sudden changes in temperature are not allowed. Reduce heating of the room. The surface maintained in such a way is very hard and is characterised by low absorptivity. Expansion joints existing in the substrate should be copied on rough floor in the form of cuts. The drying time depends on the bed thickness and also thermal conditions and humidity in a given room. It is possible to begin underlayment use after about 6 hours. Ceramic and stone floor covering can be fixed after about 3 days, whereas carpeting, PVC, linoleum or wood flooring after about 7 days (depending on the humidity of the air and the substrate). The information comprises basic instructions of product application and does not relieve users of responsibility for work in accordance with good construction practice and OHS regulations. |

| On average, ca. 20 kg of the mortar is used for 1 m2 for each 10 mm of the layer. |

| Mixing-pumping unit or slow-speed drill with mixer, wire mesh roller, brush with hard long horsehair, height bench-marks. Wash the tools with clean water directly after use. Clean the remainder of the set mortar that is difficult to remove with ATLAS SZOP. |
