Storage

Uses
Obaproof F1-88 is suitable for bonding ceramic tiles, homogeneous tiles, mosaics, etc. on:
• Both wall and floor
• Internal and external areas
• Conventional cement-sand screeds and renders
• Used with Obaproof Latex 288 for higher bond strength and flexibility
Surface Preparation
• All surfaces must be structurally sound, clean, free from dust, oil and any trace of foreign materials that may affect bonding.
• Brick and concrete walls/floors must be allowed to cure for a minimum of 4 weeks before tiling.
• Cement renders and screeds must be allowed to be cured for 7 days and finished to a semi-smooth finish with a wood float.
• Painted surfaces must be roughened with a wire brush and ensure flaking paint is removed. Water-based paints are not a suitable surface for ceramic tiles and should be removed.
Application
To achieve good adhesive to the substrates, first, apply a thin coat of Obaproof F1-88 using the smooth side of the trowel. Then, spread the adhesive mixture to the desired thickness using the toothed side of the trowel. Only spread enough adhesive so that the tiles can be fixed within the open time. Do not spot-fix or soak tiles. After spreading the adhesive, press the tiles firmly into the adhesive bed and knock the tiles lightly into position.
Remove excess adhesive from between the tiles and clean the tile faces with a damp sponge before the adhesive sets. Tiles with high ribs or lugs, grooves or an uneven back must be buttered flat or covered with a layer adhesive, in addition to the adhesive being trowelled on the substrate so that the voids are filled. The tiles must be adjusted within 30 minutes after laying and must be protected from rain or strong sun for at least 24 hours. Tile joints can be grouted usually 6 to 8 hours after laying the tiles.
For more details, please refer to our Technical Department.
Curing Time
Curing
Grouting should be carried out at least 24 hours after completion of tiling or until adhesive has dried sufficiently. Curing may be delayed on dense or impervious surfaces.
Coverage
3mm x 3mm notched trowel: Approx. 2.0-3.0kg/m²
6mm x 6mm notched trowel: Approx. 5.0-5.5kg/m²
12mm x 12mm notched trowel: Approx. 10-11kg/m²
Mixing
Add 7-8 litres clean water or Obaproof Latex 288 into 20kg of Obaproof F1-88.
Note
Do not use Obaproof F1-88 to:
• Bond tiles on walls subjected to flexing and vibration
• Bond tiles on metal surfaces
• Bond moisture sensitive stones
Cleaning of Tools
All tools and hands may be cleaned with abundant water before the adhesive sets. After setting, cleaning becomes very difficult but can usually be helped by mechanical means.

Safety
As cement is alkaline and may cause irritation, applicators are recommended to wear gloves and goggles when using Obaproof F1-88. In case of contact with eyes, flush immediately with clean water and seek medical assistance if symptoms persist.
