FOR INTERNAL AND EXTERNAL USE
|
| ATLAS HOTER S is a cement adhesive for fixing foamed polystyrene boards in ATLAS and ATLAS HOTER thermal insulation systems. It can be used on typical mineral substrates such as concrete of all grades, aerated concrete, cement render, cement-lime render, sandstone, and rough surfaces made of bricks, blocks, hollow bricks and other similar ceramic or lime-sand materials. It is suitable for indoor and outdoor use. |
 |
|
| ATLAS HOTER S is a ready-to-use dry mix of top-quality cement binder, aggregates and modifying agents. It is efficient, convenient and easy to use. It is characterised by very good workability and easy forming as well as increased adhesion, elasticity and vapour permeability. It is frost- and water-resistant. |
|
|
| The substrate should be stable, even and structurally sound i.e. strong enough; it should be free from anything that may weaken adhesion, in particular dust, dirt, lime, oil, fat, wax, remains of emulsion and oil paint. Before work commencement, clean the substrate (water under pressure) and, if necessary, use ATLAS UNI-GRUNT to reduce substrate’s excessive absorptivity. Prime also in case of such substrates as weak cement plasters, cement plasters and walls made of cellular concrete or slag concrete hollow bricks. Fill in larger irregularities and cavities with ATLAS LEVELLING MORTAR or ATLAS PLASTERING MIX. In case of adhesion of foamed polystyrene boards on weak substrates of bearing capacity that can hardly be determined (e.g. dusty, difficult to clean), it is recommended to make an adhesion test described in guidelines of the Building Research Institute no. 334/2002 “Jointless thermal insulation system of external building walls.” |

| In order to prepare the mortar, pour the whole content of the bag into a container with suitable amount of water (in proportion: 5.0÷5.5 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. The mortar is ready to use after 5 minutes and after remixing. It maintains its properties for ca. 3 hours. |
|
|
| Apply ATLAS HOTER S adhesive on the inside of the board using the “strip-point” method. It consists of preparation of continuous circumferential block (at least 3 cm wide) at the edge of the board and even distribution of 6÷8 patches of 8÷12 cm in diameter on the whole surface. In total, apply so much to cover at least 40% of board surface (after striking down to the substrate, min. 60%) and ensure appropriate board and wall connection. Immediately after application of the mortar on the board, fix the board to the substrate by firm pressing and press down so that mortar thickness under the board does not exceed 1 cm. In case of even and smooth substrates, the mortar can be evenly distributed using a notched float on the whole board surface to ensure 2÷5 mm layer thickness. If additional thermal insulation fixing using fasteners is required, begin not earlier than 24 hours after board fixing. The information comprises basic instructions of product application and do not relieve users of responsibility for work in accordance with good construction practice, method of thermal insulation work and OHS regulations. |

Foamed polystyrene board fixing - from 4.0 do 5.0 kg/m2
The exact amount of adhesive used depends on the substrate (among others, evenness) and used board adhering method. |
