Capable of accumulating water, the gel adhesive can be used for bonding claddings with different water absorption. It can be used to fix porcelain, glazed, terracotta, cement, stone (except for marble), stoneware, clinker and other tiles with different water absorption and size, including large tiles. The unique combination of specially modified minerals (including reactive silica) and additives makes the working mix highly adjustable while still maintaining the appropriate parameters and ease of application. Depending on the amount of mixing water and layer thickness, it can be used as a thixotropic adhesive for slip-free bonding of claddings on vertical surfaces or as a liquefied adhesive that eliminates air voids under the tiles and increases the contact surface on horizontal surfaces. It allows simultaneous substrate levelling with a coat thickness between 2 and 15 mm and fixing tiles. It can be used on non-deformed as well on critical substrates, such as terraces and balconies, heated or heavy-traffic surfaces, in schools, public buildings, shopping malls, train stations, public areas exposed to moisture (e.g. bathrooms, showers, kitchens, laundries). In case of fixing stone cladding, it is necessary each time to test material resistance to discolouration each time. Intended for interior and exterior use.
Product is a Component of waterproofing system ALPOL HYDRO PLUS and ALPOL HYDRO PLUS T.

Package
Single: 25 kg bag / Collective: 1200 kg shrink-wrapped pallet
Substrate type
Properly cured and seasoned cement, cement-lime and gypsum plaster, concrete substrates, cement, stone, terrazzo and anhydrite floors. Walls made of ceramic and silicate bricks and hollow clay blocks as well as of cellular concrete blocks. Old glazed, terracotta and porcelain tiles (indoors), as well as gypsum, cement fibre and gypsum fibre boards, adhering, sound and stable paint coats, stable OSB boards (with thickness ≥ 22 mm). Waterproofing layers of liquid polymer films (such as ALPOL AH 751) or polymer-cement-based sealing mortars (such as ALPOL AH 752, ALPOL AH 753, ALPOL AH 754).
Substrate preparation
Substrate should be clean, stable and sound. New plaster work and concrete should be set and seasoned. Old, loose, brittle and peeling material of poor adhesion should be removed. Chipped areas should be patched with ALPOL AZ 130 quick setting mortar or ALPOL AZ 135 levelling mortar. Treat the loose substrate with ALPOL AG 700 and ALPOL AG 703 deep penetrating primer to reduce absorption, if necessary. Remove impurities and coatings impairing adhesion from terrazzo and stone substrates and treat them with ALPOL AG 700 or ALPOL AG 702 primer. To provide a bonding coat, apply a thin layer of adhesive on old tiles, after degreasing and roughening their surface, or treat the surface with ALPOL AG 702 primer. Gypsum substrates, anhydrite floor and gypsum fibre boards should be primed twice with ALPOL AG 703 primer. Apply not thinned ALPOL AG 708 primer on OSB boards cleaned of substances impairing adhesion (e.g. by machine sanding).
Instructions for use
Stir the contents of the bag mechanically or manually with the right amount of cold and fresh water (suitable for the application) to bring the mixture to homogenous and required consistency. After 5 minutes, stir the prepared mix again. Apply the adhesive mix with a float or a putty knife and spread it with a notched trowel of appropriate notch size. When fixing tiles on critical substrate and those exposed to water penetration, apply the adhesive also on tile bottom. This step can be omitted when using the adhesive as a liquefied adhesive on horizontal surfaces, if applied using a float for medium-bed mortars, with rounded gaps between the notches. Do not soak the tiles before fixing. Apply tiles and press them against the substrate. Position can be adjusted within 20 minutes from fixing. Fix the tiles within max. 30 minutes from spreading adhesive on the substrate. There is no need to use tile spacers as the thixotropic adhesive does not flow down (no slip). Use the adhesive within 4 hours from mixing with water. If the adhesive thickens in that period of time, stir it thoroughly again without adding water. Adding too much water prolongs setting time and impairs all adhesive characteristics, such as adhesion and floating properties (slip). Unused hardening slurry cannot be mixed with water again. Throw it away.
Tools
Mixer or low-speed electric drill, basket mixer, notched trowel or trowel for medium-thick mortars with rounded inter-notch gaps, trowel, putty knife, container for the adhesive.
Working conditions
Work in ambient temperatures between +5°C and +30°C. Do not add any other agents to the adhesive. Protect the applied adhesive from excessive drying, moisture and frost.
Storage
Store in original, unopened packages in dry place – shelf life 12 months from production date. Protect from moisture during transport and storage.
Notes
The specifications and instructions for use are based on the temperature (23±2)°C and relative air humidity (50±5)%. The workability may vary depending on conditions. Becomes alkaline after mixing with water. Irritating to eyes, respiratory system and skin. Appropriate eye, respiratory system and skin protection measures should be used. In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Keep out of the reach of children. Use water to remove fresh dirt or ALPOL AI 770 cleaner to remove hardened dirt. The manufacturer assumes no liability for damage resulting from unskillful or improper use of the product.
General recommendations
Always follow best construction work practices, observing health & safety standards and regulations.
