Summary

Flexible, water and frost resistant, quick hardening special tile adhesive mortar. Has the same application areas as 3130 superfix, and is used where a quicker hardening time is demanded. Grouting after approx 1 hour.

Supplied in 15 kg plastic strengthened paper bags.

Further Details

mira 3230 superrapidfix, white

Use

mira 3230 superrapidfix is applicable for fixing of wall and floor tiles on stable substrates made of concrete, concrete elements, light weight concrete, gypsum cardboard, anhydrite or cement based plaster, cast asphalt, water or electric heated substrates, painted or primed surfaces, old tiles, terrazzo, marmox insulation board, surfaces insulated with 4400 multicoat and 4120 sealer, where quick progress of works is needed. Concrete substrates are deemed stable when approx. half of the drying shrinkage has occurred. Can substitute 3130 superfix where faster hardening of the adhesive is required.

Substrate Preparation

The substrate must be stable, dry, compact, cleaned of dust, grease, oil etc. Concrete slurry (if any) should be removed, weaker parts of substrate should be removed and then repaired again. Dust can be removed with a vacuum cleaner. Grease, oil, dirt should be cleaned with 7110 base cleaner. Absorptive substrates should be primed with mira 4120 sealer, thinned with water, in the ratio: 1 part of 4120 sealer and 3 parts of water. Non-absorptive substrate e.g. made of ceramic tiles etc. need not to be primed.

Technical conditions

a. Mixing

The mortar should be mixed for 2-3 minutes using a slow-revolving glue mixer in proportion: approx. 0.25 litres of water for 1 kg of powder, then it is ready for use.

b. Application

Prepared mortar should be applied with a smooth side of a trowel and spread well on the surface, then spread with a toothed side of a trowel. Tooth size depends on the tile size.

c. Temperature:

Minimum air and substrate temperature +6°C

d. Application time:

After mixing with water the mortar should be applied within 25-30 minutes. Spreading of mortar and fixing of tiles should be made within 10-15 min.

e. Drying time:

Grouting of joints is allowed after a period depending on absorption of the tiles and substrate and on air temperature, usually 1 hour.

Consumption:

2.5 - 6.0 kg/m2 depending on tile type and size and surface smoothness.

Technical data:

Early tensile adhesion strength* ≥0,5 MPa after not more than 24 h

Adhesion to light concrete 0,5 MPa **

Adhesion to plasterboard 0,15 MPa **

Modulus of elasticity 1,4 GPa

The product is frost- and water resistant after hardening

*According to EN 12004 1b test method 8.2 of EN 1348:1997

** Fracture in substrate.

Cleaning of tools:

Tools should be cleaned with water directly after use. Hard to remove remainings can be
removed with mira 7120 ceramic cleaner.

Packing:

3230 superrapidfix is packed in 15 kg plastic-strengthened paper bags, with handle grips.

Storage and transportation:

Transport and store dry. Storage period; min.1 year from the production date in original and undamaged packing.

Industrial safety:

The product contains cement. Its reaction with water is strongly alkaline so protect skin and eyes. In case of contact clean irritated places with water and contact a physician. Keep out from reach of children.
