ATLAS TERPLAN R
USE
TERPLAN R is a product suitable to be used for mechanically or manually making rough floors inside buildings, under terracotta or floor covering of various kinds (PVC, carpeting, parquet, floor panels, terracotta, stone, marble). It is a self-levelling cement mass, designed for levelling and adjusting the surfaces made of concrete, cement and anhydrite jointless floors as well as of other rigid and hard substrates, or for "difficult surfaces" including vinyl, ceramic, PVC, natural stone or terrazzo substrates. ATLAS TERPLAN R may be used as a connected subfloor or as a subfloor on a separation layer. TERPLAN R may be used to obtain even surfaces both in new buildings and in modernised existing buildings, in both residential and public buildings. The thickness of one layer of subfloor should be from 5 to 30 mm.
PROPERTIES
TERPLAN R is a dry mixture, reinforced with fibre, containing mineral binding agents, fillers and new generation modifying agents. It does not contain casein. After being mixed with water, TERPLAN R forms a liquid, self-levelling mass which, when bound and dried, obtains parameters required for subfloors. ATLAS TERPLAN R is efficient, convenient and easy to use.
SUBSTRATE PREPARATION
The substrate should be structurally sound and of adequate load capacity. It should be free from dust, dirt, lime, oil, fat, wax, bituminous substances, remains of paint . If it is necessary to reduce the substrate's absorptivity (high-absorption substrates, such as raw concrete, cement subfloor, rough and coarse stone floors), it is recommended to use ATLAS UNI-GRUNT PRIMING EMULSION, once or (if the substrate is characterised by higher absorptivity) twice. The second layer of the emulsion should be laid cross-wise to the first layer after about 2 hours, and no pools should be left. The priming emulsion strengthens the substrate surface, reduces absorption of water into the substrate and prevents the formation of air bubbles at its surface. Before pouring out the mass one should make additional marks on the walls to mark the location of expansion joints in the rough floor, which will be transferred to the finishing layer. During the process of the substrate preparation pay special attention to the following: the substrate should have tank-like appearance due to the risk of outflow of strongly penetrating mass; purity - contamination will float upwards to the surface; expansion joints are not necessary in case of pouring of a jointless floor over an area smaller than 20 m2. However, separation of the subfloor from the walls with the help of expansion joint tape or thin strips of foamed polystyrene is required.
MORTAR PREPARATION
In order to prepare TERPLAN R, pour dry mass into water and mix the resulting substance for several minutes with a slow-speed drill with mixer (about 400 r.p.m.), until a homogenous mixture without lumps has been obtained. The mass becomes fit for use after about 5 minutes and re-mixing. Prepare in a single step only such an amount of mortar, which can be used within 20 minutes. A mixing-pumping unit, which enables continuous flow proportioning of water, may also be used to pour the mass mechanically.
APPLICATION
To obtain rough floor of a certain height, for example in order to level the height of two contacting floors of different thickness, 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, for example, with the help of a level and portable ATLAS HEIGHT BENCH-MARKS. The mass may be poured manually or mechanically (in the latter case clean the equipment if technological breaks exceed 20 minutes). The subsequent parts of the subfloor should be connected within not more than 10 minutes. The material in the setting phase must not be diluted. It is recommended to start working at the wall situated farthest from the exit, maintaining proper pouring sequence. Do not walk on the poured mass. The mass should be poured along the wall in the form of approximately 50 cm wide belts, parallel to the wall. After having poured the mass, spread it first with a tool such as smooth metal float, raking up the excess mass and controlling the layer's thickness in this way. It is recommended that for larger areas mechanical equipment be used. Using this technology the minimum layer thickness will be approximately 6 mm. It is also recommended to de-aerate the mass using an ATLAS ROLLER or a brush with hard long hair, which has to be moved in a shaking movement along and across the surface. This operation improves the spreading process and helps to obtain a more homogenous surface. Prevent the poured mass 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. The expansion joints existing in the substrate should be repeated in the form of cuts. The drying time of subfloor depends on the layer's thickness as well as thermal conditions and humidity in a given room. Minimum drying time is 1 week. It is possible to begin the subfloor use (to walk on it) after about 6 hours and to place loads on it after approx. 3 days. Ceramic and stone floor covering can be fixed after about 3 days, and carpeting, PVC, linoleum floor covering or parquet after about 7 days (depending on the humidity of the air and the substrate).
CONNECTED SUBFLOOR
It is characterised by direct and whole-surface connection with the substrate, which should not be absorptive, therefore it is necessary to prime it first, using ATLAS UNI-GRUNT PRIMING EMULSION. Minimum thickness of layer is 5 mm (if poured manually) or 6 mm (if poured mechanically).
SUBFLOOR ON SEPARATION LAYER
This method is used on ,difficult substrates" including vinyl, ceramic, PVC, natural stone or terrazzo. On very weak, absorptive or oiled substrates TERPLAN R should be placed on a separation layer (for example one made of 0.2 mm thick polyethylene foil). The insulation should be laid tightly without creases and folded onto the walls (onto the expansion joint strips), at least up to the rough floor's height. In the 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. The minimum thickness of the subfloor is 20 mm.
COVERAGE
On average 20 kg of mortar will be used for 1 m2 for each 10 mm of the mortar layer.
TOOLS
Slow-speed drill with mixer or mixing-pumping unit, ATLAS VENTING ROLLER or hard brush with long hair, ATLAS HEIGHT BENCH-MARKS. Wash the tools with clean water directly after use. The remainder of the set mortar, which is difficult to remove, can be cleaned with ATLAS SZOP, designed to remove old cement residue.
