AK 530

Substrate type
Cement, cement-lime and lime plasters. Walls made of bricks, ceramic, silicate and cellular concrete blocks, concrete surfaces.

Substrate preparation
Substrate should be clean, dry, stable and sound. New plaster work and concrete should be set and seasoned. Remove loose, cracked and brittle plasters and widen joints. Patch slightly chipped areas with ALPOL AZ 130 quick setting or ALPOL AZ 135 levelling mortar, apply ALPOL AT 310 plaster on larger surfaces. Remove contamination and peeling paint from sound plasterwork. Dedust the surfaces. Treat the loose substrate with ALPOL AG 700 and ALPOL AG 703 deep penetrating primer to reduce absorption, if necessary.

Instructions for use
Stir the bag contents manually or mechanically with a specified amount of cold and fresh water to reach a homogeneous mix and required consistency. After 5 minutes, stir the prepared mix again. Use the adhesive within 1.5 hour from mixing with water. If the adhesive thickens in that period of time, stir it thoroughly again without adding water. Adding too much water impairs all adhesive characteristics: adhesion, stripping strength and setting time.

Bonding EPS boards:
Apply spots of the adhesive with a trowel onto the EPS board and around its edges, or spread a thin layer with a notched trowel, bearing in mind that it should cover at least 40% of the effective bonding surface. Press the boards slightly against the wall. Board position can be adjusted within 10 minutes after bonding. Bond the boards within max. 20 minutes from spreading adhesive on the substrate. Fixing with the use of mechanical fasteners can be performed after at least 1 day after bonding the boards.

Tools
Mixer or low-speed electric drill, basket mixer, notched trowel, float, trowel, 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 freshly applied adhesive work from excessive drying and moisture.

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 given for the temperature of (20±2)°C and relative air humidity of (60±5)%. The workability may alter in different conditions. Becomes alkaline after mixing with water. Irritating to eyes and respiratory system. Appropriate eye, respiratory system and skin protection measures should be used. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Keep away from children. Use water to clean fresh dirt or the ALPOL AI 770 clinker cleaner for cleaning hardened dirt. The manufacturer accepts no responsibility for damage caused by unskilful or inappropriate use of the product.

General recommendations
Always follow good building practices, observing health & safety standards and regulations. Refer to the application manuals for ALPOL insulation systems, ITB instructions or indications provided in this data sheet for details on bonding insulation boards and insulating walls.
