Description
BAL SPF S1 Standard Set Tile Adhesive is a standard-setting, highly polymer-modified, water/frost-resistant cementitious tile adhesive for walls and floors. Available only in white, in 20kg bags.
BAL SPF S1 Standard Set Tile Adhesive features an extended open time of 30 minutes and a pot life of 5 hours. Tiles can be grouted after 16 hours (at 20°C). Suitable for bed thicknesses of 2-6mm.
BAL SPF S1 Standard Set Tile Adhesive can be used for fixing ceramics, porcelain and vitrified tiles, mosaics, certain natural stones, terrazzo, rigid foam insulating materials and brick slips in dry or wet interior and exterior environments. NOTE: Certain types of natural stone (i.e. limestone, marble, travertine and some granite) may be susceptible to water staining. In this case, use of a BAL Flexible Rapid-setting white BAL adhesive is recommended i.e. BAL RAPID-FLEX ONE.
BAL SPF S1 Standard Set Tile Adhesive is recommended for large format wall tiles, areas of total immersion in water (e.g. swimming pools and showers), installations subject to limited movement and vibration, and heated screeds.
However, BAL SPF S1 Standard Set Tile Adhesive is NOT suitable for: Metal, painted, Glass/metal tiles with water-sensitive coating on back, plywood walls and tiling to existing glazed tiles, ceramic panels (e.g.3m x 1m in size).
Surface Preparation:
BAL SPF S1 Standard Set Tile Adhesive is suitable for surfaces include: Brick/Concrete, Rendering, BAL Board/Tile Backer Board/Fibre Cement Boards, Cement:Sand Screed, Anhydrite/Calcium Sulfate Screeds, Mastic Asphalt, Vinyl Tiles/Sheets, Plaster, Plasterboard, Unglazed Ceramic Tiles/Hard Natural Stone, Lightweight Blockwork, Overlaid Timber Floors (15mm min), Timber Floors, Glazed Tiles.
Ensure surfaces to be tiled are flat, clean, dry, sound, free from contamination and all barriers to adhesion.
In wet areas: waterproof background with BAL TANK IT and BAL Waterproof 1C .
If tiling externally, provide protection against inclement weather during fixing and grouting and for as long as possible afterwards. It is recommended that all direct to earth sub floors include a DPM or, if required a surface DPM can be applied prior to tiling.
Application/Usage:
Do NOT use BAL SPF S1 Standard Set Tile Adhesive in temperatures below 5°C or in damp conditions.
BAL SPF S1 Standard Set Tile Adhesive may be applied on walls and floors using a suitable notched trowel. N.B. For larger format tiles, the reverse of the tile should be back buttered with a thin layer of adhesive to ensure solid bedding. NOTE: For thick applications, the mixing water should be reduced to achieve the necessary slump resistance. Do not use thicker beds of adhesive with porous or soft bodied tiles.
Fixing procedure:
1. Apply adhesive to wall or floor surface and comb to required bed thickness ensuring the ribs of adhesive all run in one direction. The adhesive may be applied to a bed thickness of 2 – 6mm or up to 12mm in limited, localised areas. (i.e. MAX 0.5m²) If fixing large/heavily patterned tiles, apply additional adhesive to tile reverse.
2. For mosaics: using a rubber tile float, press mosaics into adhesive and beat into required position. For tiles: press tile firmly into the ribs of the adhesive and into position, with slight twisting/sliding action to ensure optimum adhesive contact.
3. Fix mosaics/tiles before adhesive forms skin (typically over 30 minutes at 20°C, depending on surface porosity /atmospheric conditions). If skin has formed, remove adhesive and apply fresh layer). Discard any adhesive that has begun to set. Do not add further water.
Mixing:
Use a BAL MIXING BUCKET or other suitable bucket.
1. Add approximately 3.5 to 4 parts powder to 1 part clean cold water by weight. (5.4 – 5.6 litres per 20kg of BAL SPF S1 Standard Set Tile Adhesive Powder) Never add more water than recommended as this may lead to excess shrinkage or de-bonding.
2. Mix until lump-free mortar achieved.
3. Allow mixed BAL SPF S1 Standard Set Tile Adhesive adhesive to stand for 2 minutes before re-mixing for 30 seconds. If using electric drill mixer, blend at slow speed (i.e. under 300rpm). Pot life at 20°C: approx. 5 hours. NOTE: Pot life/setting time of BAL SPF S1 Standard Set Tile Adhesive will vary slightly with temperature: higher temperatures = shorter; lower temperatures = longer.
4. Occasionally lift a mosaic/tile to check adhesive contact area. When solid bed fixing, leave no voids behind tiles.
5. Leave adequate joints between individual tiles. Install movement joints to BS 5385, Parts 1-5.
6. Clean off surplus adhesive from tile face and between tile joints before the adhesive has dried.
Grouting:
1. Wait minimum 16 hours (at 20°C) after tile fixing. Select a BAL cementitious such as BAL MICROMAX3 ECO GROUT or epoxy grout i.e BAL ABSOLUTE GROUT.
If using paper-faced mosaics: Pre-grout sheet and remove surplus. Place in position and tap down to achieve full contact with adhesive. Ensure joints between sheets match joints between mosaic tesserae (i.e. staggered). Wet paper and carefully remove before adhesive fully hardens. Clean off surplus adhesive and grout from mosaic face. Finish grouting.
2. Fill movement joints with suitable sealant i.e. BAL MICROMAX SILICONE SEALANT. However, do NOT use on sensitive surfaces that could react to acetic acids released during cure. For intermediate movement joints, a more durable hard-wearing material may be needed e.g. an epoxy polysulphide sealant or a suitable pre-formed movement joint strip.
NOTE: If completing a swimming pool using BAL SPF S1 Standard Set Tile Adhesive, do NOT fill pool for at least 3 weeks after grouting (contact BAL TECHNICAL ADVISORY AND SPECIFICATION SERVICE for further advice). If completing a shower, do NOT use shower for at least 2 weeks (as required by latest version of BS 5385: Part 4).
