MTA is a ready-mixed high quality joint grout with high plasticity and good adherence, has ability to resist glissade excellently thanks to extremely thin glue. Components of MTA include binding materials of polymer concrete mixture, are mixed with dry sand and other special admixtures according to formula developed and researched by IRONX’s Laboratory
MTA is used to tile all kinds of ceramic tiles, mosaic tiles, unburned tiles, natural or artificial tiles with different sizes, tiling all kinds of normal tiles with size of <400 x 400 mm in indoor and outdoor areas.
Indoor and outdoor floors:
- Concrete plates, intermediate beams, concrete floor
- Cement overlay and sand cement mortar layer on the ground
- Floor with hot air duct system below
- Indoor and outdoor walls
- Concrete walls, cement mortar
- Indoor gypsum walls
Improving floor and old wall:
Especially, MTA allows to directly fill joints in the surface layer of old brick and stone tiles without destroying the entire paving materials including mortar layer of base coat, old brick layer and stone tiles as traditional construction methods
Firstly, using the straight edge of smoothing trowel to coat a thin layer (around 1mm) to the surface of base. Then using the serrated edge of trowel to cover an adhesive layer in the base with appropriate thickness of materials
MTA allows to execute with one layer with amount of 3 kg/m2
If the thickness is greater, 2 sticky layers shall be implemented by using serrated trowel to cover another thin layer of glue in the back of bricks and tone tiles before sticking.
The thickness of adhesive: from 2 to 10mm
The use of glue amount depends on the size of brick and stone tiles in accordance with sizes of serrated trowel as recommended by the manufacturer as follows:
1. Using trowel size 4 with thickness of 2mm for brick tiles and stone tiles with size of < 300 x 300 x 10mm.
2. Using trowel size 6 with thickness of 3mm for brick tiles and stone tiles with size of < 600 x 600 x 10mm
3. Using trowel size 8 with thickness of 6 mm for brick tiles and stone tiles with size of < 600 x 600 x 10mm
Precautions: MTA is a cement based product so that it has alkaline features. It is necessary to implement appropriate
measures to minimize the contact with skin. If it contacts with eyes, cleaning immediately with water and go to the doctor
