Description

Obaproof F1-88 is a water-resistant cement-based, thin or medium bed adhesive, suitable for fixing ceramic tiles, etc. to wall and floor, dry or wet interior and exterior areas with very good adhesion strength.

Uses

Obaproof F1-88 is suitable for bonding ceramic tiles, homogeneous tiles, mosaic, etc. on:

• Both wall and floor
• Internal and external areas
• Conventional cement-sand screeds and renders
• Used with Obaproof Latex 777 for higher bond strength and flexibility

Advantages

• Good bonding strength
• Easy installation/User-friendly
• Excellent water and impact resistance
• Non-flammable
• Non-toxic

Limitations

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

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 tilings. Cement renders and screeds must be allowed to be cured for 7 days and finished to semi-smooth finish with a wood float. Painted surfaces must be roughened with a wire brush and flaking paint removed. Waterbased paint are not a suitable surface for ceramic tiles and should be removed.

Mixing

Add 7-8 liters clean water or Obaproof Latex 777 into 25kg of Obaproof F1-188

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

Application

To achieve good adhesive to the substrates, first, apply a thin coat of Obaproof F1-188 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 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 layered 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.  

Curing

Grouting should not be carried out for at least 24 hours after completion of tiling or until the adhesive has set dried sufficiently. The setting may be delayed on a dense or impervious surface.

Cleaning

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.
