QUICK-SETTING MORTAR (from 5 mm to 30 mm) FOR CONCRETE SUBSTRATES AS WELL AS SUBFLOORS AND SCREEDS MAKING

FOR INTERNAL AND EXTERNAL USE

USE

ATLAS TEN-10 is a quick-setting mortar designed for repairs of concrete and ferroconcrete as well as subfloors and rough floors on which large loads are imposed. ATLAS TEN-10 is suitable for very quick renovation or restoration of damaged concrete or ferroconcrete elements e.g. columns and binding joists, rough floors and subfloors. It is perfect for edges and whole surfaces of balconies and terraces, stairs and staircase landings, road curbs as well as for repairs of loading ramps and access roads, and for substrates with a slope. The thickness of the mortar layer should be 5÷30 mm. It is suitable for indoor and outdoor use.

PROPERTIES

ATLAS TEN-10 is ready-to-use dry mix based on top-quality cement binder, quartz fillers and improvers. It is characterised by high initial strength, very good resistance to concentrated and abrasive loads (compressive strength after 1 day is min. 20 N/mm2, bending strength after 1 day is min. 3.5 N/mm2) and excellent adherence to the substrate. It is very easy and convenient to use. Thick consistency enables to form slopes freely and quick setting time enables to walk on the surface 3 hours after subfloor or rough floor preparation. ATLAS TEN-10 is frost- and water-proof.

SUBSTRATE PREPARATION

The substrate should be dry structurally sound i.e. i.e. strong enough, free from anything that may impede rough floor adhesion, in particular dust, dirt, lime, oil, grease, wax, bitumen, paint, etc. Mechanically remove loose elements and parts of substrate of poor strength. While preparing rough floor or subfloor, walls and other elements within the range of conducted work e.g. pillars should be separated (using expansion joints) from the underlayment using ATLAS EXPANSION TAPE or thin foamed polystyrene boards. Make additional marks on the walls to mark the location of expansion joints in the substrate that will be transferred to the rough floor. Substrate surface should be rough and porous. Existing scratches and cracks should be widened mechanically up to at least 5 mm. Smooth substrates should be hammered in order to achieve rough surface. Immediately before mortar application, it is recommended to moisten the substrate with water and to apply a contact layer over the substrate, prepared as follows: 10 kg of ATLAS TEN-10 + 1.8 l of water + 0.9 l of ATLAS ELASTIC EMULSION. It is sufficient to cover ca. 10 m2.

MORTAR PREPARATION

In order to prepare an appropriate layer, pour dry mortar into a container with suitable amount of water (in proportion: 3.00÷3.75 l water for 25 kg of dry mortar) and mix until homogenous. It is best to mix it mechanically, using a drill with a mixer or in a concrete mixer. The mass is ready to use immediately after mixing. It maintains its properties for 40 minutes. Select the ratio of added water experimentally, following the desired consistency of the mortar, type of substrate and weather. Inappropriate amount of water for mass preparation results in deterioration of strength parameters of the rough floor or subfloor.

APPLICATION

When the substrate is prepared and moistened with water, apply liquid contact layer (prepared according to the instructions given above) with a brush or paintbrush. Only then ATLAS TEN-10 mortar can be applied, using the wet-on-wet method and a float made of steel. While placing the mortar the existing scratches and cracks should be filled thoroughly (by pressing). When the contact layer dries before the application of the main repair layer, it has to be prepared again. Combine successive portions of the mortar before material setting. The mortar, depending on the thermal conditions and humidity, begins to set after ca. 1 hour. At that time, as required, smooth the surface. Protect the surface from precipitation and drying too quickly during work and immediately afterwards (if required, moisten it with water or cover it with foil). When using ATLAS TEN-10 for making subfloors or rough floors, observe the same rules as those concerning concrete floors, taking into account the short setting time of the mortar as well as expansion joint preparation. It is possible to use the subfloor (walk on it) after ca. 3 hours. 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.

CONSUMPTION

On average, ca. 20 kg of dry mass is sufficient for 1 m2 for each 10 mm of thickness.

TOOLS

Drill with a mixer, trowel or float made of steel. Wash the tools with clean water directly after use. Clean the remainder of the set mortar, that is difficult to remove, with ATLAS SZOP.
