BLUE LABEL

DESCRIPTION
Blue Label is a grey, acrylic based, flexible, pre-mixed, interior, thin bed, wall and floor tile adhesive.
USES

Blue Label can only be used for interior wall and floor tiling installations.

Blue Label can be used for thin bed fixing of tiles directly onto fibre cement sheeting, plasterboard and rendered walls, as well as timber floors, with a correctly installed fibre cement sheet tile underlay.

Blue Label, when used on floor areas is only suitable for light domestic trafficked areas.

Blue Label can be used to fix most types of porous ceramic and marble wall and floor tiles, with the exception of light coloured or green marbles.

When using Blue Label with translucent/ absorbent tiles, the colour of the adhesive must be considered, so as to avoid discolouration problems.

Blue Label must not be applied directly over concrete, timber or waterproofing membranes.
FEATURES & BENEFITS

Water resistant bond

Will absorb vibration and reduce sound transmission

Pre-mixed – ready for use!

High bond strength

Blue label surpasses the Australian Standard AS 2358-1990
SURFACE PREPARATION

All surfaces must be structurally sound, dry, clean and free from movement, oil, grease, wax, curing compounds and any other loose or contaminating materials.

All building boards must be flat and firmly fixed according to the manufacturer’s instructions and relevant Australian Standard(s).

Painted surfaces must be scabbled/abraded to expose at least 80% of the original substrate.

Newly rendered surfaces must be allowed to cure for at least 7 days and have a wood float finish.

Old rendered surfaces must be thoroughly cleaned prior to tiling and have a wood float finish.

Porous/dusty surfaces must initially be primed using Davco Ultraprime.
Movement joints should be provided as follows:
1.
Over movement joints in the background.
2.
At a junction between different background materials.
3.
At fixtures interrupting the tile surface e.g. columns.
4.
At internal vertical corners.
5.
Around the perimeter of the tiling system.
6.
At a maximum of 5 metre intervals in a grid pattern.
Note: Movement joints should go right through the tile and adhesive bed to the background and be kept free from dirt and adhesive droppings. Movement joints should not be more than 6mm wide nor greater than 10mm wide. Movement joints that are 6mm wide can be filled with Davco Sanitized® Colorcaulk. For wider applications use Davco Davsil, polysulphide or polyurethane type fillers.
APPLICATION

Spread the adhesive onto the substrate using a 6mm x 6mm notched trowel for installation of wall tiles up to 150mm x 150mm.

For the installation of floor tiles or wall tiles larger than 150mm x 150mm use a 10mm x 10mm-notched trowel.

Tiles with lugs, grooves or an uneven back must initially be butter coated with the adhesive, in addition to the adhesive being trowelled onto the substrate.

For mosaic tiles, use a 6mm x 6mm-notched trowel.

A minimum final bed thickness of 2mm is recommended for wall tiles, whilst a minimum final bed thickness of 3mm is recommended for floor tiles, but the final bed thickness in either case must not exceed 4mm.

Do not spread more than 1m2 of adhesive at any one time.

Press tiles firmly into position before the adhesive skins, ensuring that all the tiles are well bedded and that no voids occur under the tiles.

Occasionally, in order to ensure that full coverage is being maintained, a tile should be removed, the adhesive coverage noted and the tile relaid accordingly.

Once the tiles have been laid, they must not be disturbed for 24 hours at 20oC.

 GROUTING
PACKAGING

Grouting can be carried out 24 hours after the completion of tiling.
Available in 1, 4, 10 and 20 litre containers.

Use the Davco grout that best suits the tiling installation. Refer to the Davco Adhesive and Grout Selection Guide for further information.
SHELF LIFE
Blue Label in unopened containers, has a shelf life of up to 12 months, stored in a cool, dry place.

To enhance colour, increase water resistance and flexibility of the grout, use Davco Grout Additive. This is particularly recommended when grouting over timber or fibre cement sheeted floors, to minimise the likelihood of the grout cracking/powdering.
