Usage

Use 3650 multipox for bonding and grounting of tiles and clinkers on stable substrates. 3650 multipox is a very strong adhesive/grout. It resists most environmental influences and is therefore suitable for industrial environment with risk of chemical exposure, and where there are special requirements for hygiene and cleaning eg in food- and pharmaceutical industry etc.

3650 multipox is a 2-component adhesive/grout. Binder and hardener are mixed in the bucket immediately before use.

Product description

2-component epoxy adhesive and grout for professional use. Chemical resistant and with high tension and compression strength.

Applications areas

For mounting and grouting of ceramic tiles, mosaics, clinker, natural stones, ceramic granite tiles etc. inside and outside, in wet and dry areas - NOT recommended for absorbent natural stone and marble. 3650 multipox can be used outdoors, however, UV radiation may change colour of the joint.

Pre-treatment of substrate

Ensure the substrate has carrying capacity, is sound and coherent, free of dust, grease and oil etc. The substrate must be dry.

When mounting on old tiling and painted surfaces, ensure that old tiles or paint adheres to surface and do not come off.

Mixing

Products must have temperature of min. +10°C. Mix in the bucket in which product is supplied, with a slow rotating mixing paddle. Pour curing agent (component B) into binder (component A) and mix thoroughly with slow moving mixing paddle for about 2 min. to homogeneous mass. Pot life 30-60 minutes after mixing.

Adhesion

3650 adhesive is spread on the substrate with the smooth side of notched trowel, then draw the notched side through adhesive. Follow recommendation for correct choice of tooth size for tile type and substrate.

The tiles are pressed/twisted in place in the wet adhesive. Ensure that the back of tile is fully covered. Cavities create a risk of the adhesive sinking during the curing process and causing holes in the adhesive layer.

The hardening time of the product depends on the room temperature. At +20°C, the tiled surface is ready for grouting after 1-2 days.

Grouting

Apply the grout with the special epoxy float mira 4575 groutmaster. The groutmaster is drawn diagonally over the tiles, and the grout is worked thoroughly into the joints to achieve a compact filling. Excess grout is removed immediately with the float to ease the cleaning later on. When the grout has set after  15-30 minutes at least, moisten the entire surface with plenty of water mixed with mira 7250 epoxy remover (in a 1:20 ratio) and scrub with a padmaster. Then remove excess grout and grout haze with sponge and shape joints.

Joints can still be shaped after 3-6 hours.

Any excess grout can be removed after 9-12 hours with mira 7120 ceramic cleaner diluted with water in ration 1:2. Remove washing water from tiles with sponge (use warm water) or water vacuum cleaner (floor). Carefully remocve all haze from the surface of the tile, as the cured grout is much more difficult to remove (can only be removed mechanically).

Clean the tools immediately after use with warm water mixed with a a small amount of mira 7250 epoxy remover.
