ATLAS PLUS S2 HYDRO can be applied in three forms:
- as an adhesive for tiles,
- as an adhesive and waterproofing coat in one technological cycle,
- as a waterproofing coat.
 
Three technologies are used in the recipe of ATLAS PLUS S2 HYDRO adhesive: POLYMER TECHNOLOGY, DOUBLE FIBERS TECHNOLOGY and TECHNOLOGY OF MODIFIED RUBBER ELASTOMER FILLERS.
Owing to high content of polymer compounds, fibres and modified rubber fillers, the adhesive obtains unique properties and offers the highest technical and operational properties and long-term durability.

POLYMER TECHNOLOGY

Go top
The presence of polymers ensures great bonding between cladding and substrate of any type, also so called difficult and critical ones. Owing to the interchange of the polymer network with the network of inorganic hydration cement bindings, the adhesive offers outstanding parameters.
 
The use of the POLYMER TECHNOLOGY in ATLAS PLUS S2 HYDRO brings the following advantages:
• durable and strong bonding between cladding and difficult and non-absorbable substrates,
• possibility of use on substrates exposed to high deformation and vibration,
• high resistance to extreme operational loads – mechanical and thermal,
• excellent bonding to cladding of any type,
• safe use with tiles of any size, also with tiles up to 5 m² large,
• perfect workability and rheology.

DOUBLE FIBERS TECHNOLOGY

Go top
ATLAS DOUBLE FIBRES TECHNOLOGY is based on a mix of polypropylene and cellulose fibres.
The polypropylene fibres used in this technology are materials characterised by high chemical resistance to acids, bases, solvents or salt action. They are hydrophobic, almost non-absorbable, therefore resistant to microbiological corrosion. The fibres improve mechanical performance of the mortar as they form diffused reinforcing within the mortar structure. The cellulose fibres get elastic and ductile under water action. They increase their volume and enable free transport of water along fibres, thus significantly influence the mortar workability – improve mortars rheology, reduce slip, extend open time and increase the substrate wettability. Cellulose fibres prevent too quick water retention by the substrate, therefore set ATLAS PLUS S2 HYDRO gets the best technical performance, such as bonding to the substrate and strength.
 
DOUBLE FIBERS TECHNOLOGY in ATLAS PLUS S2 HYDRO brings the following benefits:
·         increase of strength parameters,
·         significant increase of resistance to the effects of high operational loads as well as impact loads and vibrations,
·         safe fixing at large temperature differences,
·         compensation of tension arising on deformable substrates,
·         improvement of water retention in adhesive mortar: fibres limit results of rapid water absorption, also in combination with absorbable substrate and absorbable tile and in evaporation area; during setting and drying of the adhesive mortar (especially applied with maximum thickness), fibres are accumulating and transporting water, maintaining its unified level within the whole layer,
·         reduction of the effect of tile ‘pulling’,
·         significant increase of working parameters,
·         increase the tiles stability immediately after bonding to the substrate.

TECHNOLOGY OF MODIFIED RUBBER ELASTOMER FIBERS

Go top
TECHNOLOGY OF MODIFIED RUBBER ELASTOMER FILLERS in ATLAS PLUS S2 HYDRO brings the following benefits:
·         quick and easy application,
·         perfect rheology and workability,
·         high deformability,
·         possibility of application on substrates exposed to high operational loads – mechanical and thermal, deformations and vibrations,
·         compensation of thermal tensions even on large-size dark tiles applied on terraces and façades.

PROPERTIES

Go top
ATLAS PLUS S2 HYDRO is manufactured as a dry mix of high quality cement binder, aggregates and special composition of modifiers.
 
Highly flexible – deformability of S2 class (test according to the PN-EN 12002 standard).
 
Three times greater initial bonding, i.e. ≥ 1.5 N/mm².
 
Range of adhesive thickness (2-10 mm) enables:
- thin-coat cladding fixing on even substrates,
- thin-coat cladding fixing on uneven substrates, preceded by the substrate floating.
 
Extended open time - allows placing tiles on the adhesive even 30 minutes since application upon the substrate – the mortar can be once applied onto larger surface which significantly reduces the time of application.
 
Reduced slip - enables fixing cladding “from top to bottom” – proper consistency and layer thickness eliminate the adhesive slip. Therefore one can tile from the wall top and avoid cut-to-size tiles on exposed wall zones.
 
Versatility of use – the adhesive is designed for almost any cladding type, regardless the tile size (even above 5m2), on various substrates, in any building type, even with high operational loads.

SUBSTRATE PREPARATION

Go top
The substrate should be:
• stable – sufficiently sound, resistant to deformation, free from materials which would impair bonding, stabilized.
• even – maximum adhesive thickness is 10 mm, in case of larger irregularities use ATLAS ZW 330 or ATLAS ZW 50 levelling mortars or ATLAS SMS, SAM or POSTAR screeds.
• clean – free from layers which would impair adhesive bonding, especially dust, dirt, lime, oils, greases, wax, residues of oil and emulsion paints; substrate coated with algae, fungi, etc. must be cleaned and protected with ATLAS MYKOS agent.
• primed:
- with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS – substrates of excessive or heterogenous absorptiveness,
- with ATLAS GRUNTO-PLAST – if the substrate absorptivity is poor or it is coated with layers limiting bonding,
- with ATLAS ULTRAGRUNT – while adhesive will be applied on critical substrates.
 
Detailed guidelines concerning the substrate preparation, depending on its type.
Substrate type
Preparation
Freshly applied cement screeds ATLAS POSTAR 80, ATLAS SMS 15 or ATLAS SMS 30
Stabilized min. 24 hours; optimum moisture content < 4% by weight.
Freshly applied cement screeds ATLAS POSTAR 20
Stabilized min. 2 days; optimum moisture content < 4% by weight.
Other cement screeds
Stabilized min. 28 days; optimum moisture content < 4% by weight. Prime with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS.
Anhydrite screeds ATLAS SAM 100, ATLAS SAM 150, ATLAS SAM 200 or ATLAS SAM 500
Stabilized min. 2-3 weeks; optimum moisture content < 0.5% by weight. Prime with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS. If, white surface tarnish forms during screed drying, it should be removed mechanically (grinded) and the surface dedusted. Screed grinding accelerates the process of drying.
Cement and anhydrite screeds on floor heating
Appropriately heated and primed with ATLAS UNI-GRUNT or ATLAS UNI-GRUNT PLUS
Terrazzo
De-grease the surface thoroughly, in case of waxed terrazzo remove the top layer or whole layer and execute a new one. Prime with ATLAS ULTRAGRUNT.
Walls made of silicate or ceramic bricks and hollow blocks, cellular concrete
Levelling coat required (plaster). Direct fixing onto rough wall is possible in case of appropriate substrate dimensional tolerance. In such case it is necessary to execute full joint wall (or re-fill the joints) and repair any gaps or irregularities with ready-to-use mortars.
Prime with ATLAS UNI-GRUNT.
Cement and cement-lime plasters made of ready ATLAS mortars
Stabilized min. 3 days* for each 10 mm of thickness; optimum moisture content < 4% by weight.
Other cement and cement-lime plasters
Stabilized min. 7 days*. Prime with ATLAS UNI-GRUNT.
Gypsum plasters
Prime with ATLAS UNI-GRUNT. If gypsum plaster is applied in a wet room it should be thoroughly protected against moisture. If dampness has form of short term action or moderate water splash, then the plaster should be coated with a preparation improving resistance against damp penetration, e.g. ATLAS GRUNTO-PLAST.
Substrates levelled with ATLAS ZW 330 mortar
Stabilized min. 5 h for layer thickness 5 mm.
Stabilized min. 10 h for layer thickness 10 mm.
Stabilized min. 20 h for layer thickness 20 mm.
Stabilized min. 48 h for layer thickness above 20 mm.
Substrates levelled with ATLAS ZW 50 mortar
Stabilized min. 12 h for layer thickness 5 mm.
Stabilized min. 24 h for layer thickness 10 mm.
Stabilized min. 3 days for layer thickness 20 mm.
Concrete
Stabilized min. 21 days; optimum moisture content < 4% by weight. Remove residues of formwork oils and other substances which would impair adhesion. Prime with ATLAS ULTRAGRUNT. Holes, cracks and other gaps should be filled with ATLAS TEN-10 or ATLAS ZW 330 mortars.
Concrete reservoirs for drinking water, technological tanks, pool basins, made of watertight concrete
Grinding, sanding or wet sanding required in order to open the surface pores.
Water reservoirs, pool basins, wading pools, etc., surfaces waterproofed with elastic mortars or liquid foils
If required, clean the waterproofing coat delicately, so the coat is not damaged.
Oil paints and resin lacquers coatings
Coatings of poor bonding to the substrate should be mechanically removed. Stable, well bonded coatings: grind, dust; prime oil coatings with ATLAS ULTRAGRUNT. Remove any gypsum fillers used for substrate evening.
OSB boards and wooden floors – the layer composition should be designed and executed in the way excluding the possibility of deformation which may lead to the cladding damage.
-check the boards type, on floors one may use boards OSB/3 and OSB/4 (acc. to PN-EN 300:2007), min. 25 mm thick, on walls – min. 18 mm thick,
- check the superstructure stability, boards must not move under operation load; fix additional, stiffening boards layer, if needed,
- matt the surface with 40-60 sand paper,
- dedust the surface.
Existing ceramic or stone tiles
- check bonding to the substrate of the existing cladding by tapping; individual loosening tiles must be removed,
- clean and de-grease the existing tiles surface,
- matt glazed tiles with a diamond grinder,
- dedust the surface
- prime with ATLAS ULTRAGRUNT
Metal and steel surfaces
Cleaning and rust removal required, prime with ATLAS ULTRAGRUNT.
Plastic surfaces
Cleaning, grinding and priming with ATLAS ULTRAGRUNT required. Perform the bonding test prior to the cladding fixing in order to confirm the plastic substrate binding ability.
*) The time shown in the table is recommended for application at the temperature 20°C and humidity 50%.

CLADDING FIXING

Go top
Adhesive preparation
Pour adhesive from a bag into a container with suitable amount of water (see Technical Data for ratio) and mix using a low speed mixer with a drill for mortars until homogenous. The dispersed adhesive should be left to rest for 5 minutes and remixed then after. So prepared adhesive should be used up within approx. 2 hours.
Application of waterproofing coat and tiles fixing in one technological cycle:
STEP 1: Application of ATLAS SEALING TAPES, CORNERS and RINGS or ATLAS HYDROBAND 3G. Apply a contact coat on the area of application of accessories by rubbing ATLAS PLUS S2 HYDRO into a moistened substrate with a sharp trowel edge or a brush for sludging. Then apply adhesive with a notched trowel of notch size 4. Excessive adhesive should be pressed out with a sharp edge of a trowel.
STEP 2: Installation of ATLAS eaves profiles for balconies and terraces. Installation should be carried out in compliance with the Technical Data Sheets of profiles, with waterproofing layer made of ATLAS PLUS S2 HYDRO.
STEP 3: Application of the waterproofing coat. Moisten the substrate. Apply a contact coat by rubbing ATLAS PLUS S2 HYDRO into the substrate with a sharp trowel edge. Apply the adhesive with a steel trowel of notch size 10, then smoothen the surface.
STEP 4: Installation of cladding with the ‘wet on wet’ method. The adhesive should be applied on the bottom side of a tile. It is recommended to rub a thin layer of the adhesive, then apply a a thicker layer of mortar with a notched trowel of notch size min. 6.
 
Application of waterproofing coat and tiles in two technological cycles:
The waterproofing coat application should be carried out in similar manner to the one detailed above, steps 1-3. Cladding fixing - when the waterproofing coat sets, the cladding can be fixed with the use of any application method and with a notched trowel of notch size min. 6.
 
Cladding fixing
The adhesive should be applied onto the surface with a steel trowel, distributed uniformly and shaped (possibly in one direction) with a notched trowel. It is advisable to spread a thin adhesive coat first and then apply the coat of desired thickness and shape it with a notched trowel. It is recommended to lead a notched trowel in one direction. On walls, it’s recommended to shape the adhesive vertically.
In the case of tiles installed on a floor, outdoor cladding or large-size tiles, it is recommended to coat the whole tile surface with an adhesive (if needed, use the combined method – apply the adhesive mortar on a substrate and the bottom side of a tile).
For fixing large-size tiles 300x100 mm and larger, one of three variations of the combined method is recommended:
-      adhesive mortar on the substrate with a trowel 8 mm + adhesive on a tile with a trowel 6 mm,
-      adhesive mortar on the substrate with a trowel 10 mm + adhesive on a tile with a trowel 4 mm,
-      adhesive mortar on the substrate with a trowel 12 mm + adhesive on a tile with a trowel, smoothened – 1 mm,
After application, the adhesive retains its properties for approx. 30 minutes (at temperature approx. 23 °C and 55 % humidity). Within this time, the tiles must be placed and pressed well (the contact surface between the adhesive and the tile should be uniform and as large as possible – min. 2/3 of the tile surface). Remove excessive adhesive pressed into the joints immediately. Keep the joint width appropriate for the tile size and operational conditions (check data in the data sheets of ATLAS grouts).
 
 
Tile adjustment
The position of a tile can be adjusted with delicate moves along the plane of bonding. It can be done within approximately 10 minutes since the tile is pressed (at temperature approx. 23 °C and 55 % humidity).
 
Grouting and cladding use
It is advisable to use ATLAS grouting mortars. Grouting of cladding applied on a wall is possible after 24 hours since the tiles fixing. Foot traffic and grouting of floor cladding is possible after 24 hours since the tiles fixing. The mortar reaches operational strength after 3 days (check the Technical Data section). Expansion joints, joints along the wall corners, at sanitary equipment, etc. should be filled with sanitary silicone ATLAS SILTON S or ATLAS ARTIS.

IMPORTANT ADDITIONAL INFORMATION

Go top
• The tiles must not be soaked before fixing. When determining the adhesive thickness under the cladding, one should consider the geometric deviation of tiles shape, e.g. plane warpage.
• Conduct test application prior to natural stone tiles or glass elements fixing – apply a single tile. Keep the 60% of surface bonding (leave 40% of a tile with no contact with adhesive). Check the tile appearance after 2-3 days. The test is passed when there is no difference of shade of tile surface in contact and not in contact with the adhesive.
• Open time – from the moment of application of adhesive to the moment of placing the tiles upon it – is limited. In order to check if it is still possible to fix tiles, performing a test is recommended. It consists in pressing fingers against the adhesive. If the adhesive remains on fingers, one can fix the tiles. If  fingers are clean, the old layer of adhesive has to be removed and a new one applied.
• The tools must be cleaned with clean water directly after use. Difficult to remove residues of set adhesive can be removed with the ATLAS AGENT FOR REMOVAL OF CEMENT DEPOSITS AND STAINS
• Contains cement. May cause respiratory irritation. Causes skin irritation. Causes serious eye damage. May cause an allergic skin reaction. Keep out of reach of children. Avoid breathing dust. Wear protective gloves/protective clothing/ eye protection/face protection. IF ON SKIN (or hair): Remove/Take off immediately all contaminated clothing. Rinse skin with water/shower. If skin irritation or a rash occurs: Get medical advice/attention. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing. Follow the instructions of the Safety Data Sheet.
• The adhesive must be transported and stored in tightly sealed bags, in dry conditions (most preferably on pallets). Protect against humidity. Shelf life of mortar packed in foil bags in conditions as specified is 15 months from the production date shown on the packaging. Content of soluble chromium (VI) in ready-to-use mix - ≤ 0.0002%.
