Tibmix can also be used to suppress steel fibres in concrete floors. Coloured versions of Tibmix are also available which contain a high quality, durable pigment. When trowelled into freshly laid concrete, Tibmix produces a dense, tough, abrasion resistant surface suitable for most industrial floors. The product is designed for application either by hand or using automatic spreading equipment.
Tibmix should be used in conjunction with Setseal 6 polymer curing membrane/sealer/hardener.
25 kg polythene-lined paper sacks.
Recommended application rate of 5.4 kg/m² depending on application - please contact our Technical Department.
Store under cover, in unopened bags clear of the ground in cool dry conditions, protected from frost and excessive draught.
When stored as above, and used within 9 months of the date shown on the packaging, the activity of the reducing agent added will be maintained and the mixed product will contain no more than 0.0002% (2ppm) soluble chromium (VI) on the total dry weight of the cement.
9 months in unopened bags stored under good conditions.
* Anti-static properties: Conforms to the requirements of Table 2 of BS 2050: 1978, which specifies the requirements for anti-static industrial and hospital flooring.
The base concrete should be a minimum grade C32/40 with a cement content no less than 325 Kg/m³ and should be placed in accordance with good concrete practice.
The water: cement ratio should be kept to the minimum needed to produce a fully compacted concrete without excess surface water. Should free water be present at the surface this should be allowed to evaporate or brushed away, before the application of Tibmix.
Broadcast the Tibmix evenly over the surface of the base concrete. Where manual trowelling is involved, application in two stages is recommended. The first stage should be to apply two thirds of the coverage rate of Tibmix following removal or evaporation of surface bleed water. Immediately after this stage Tibmix should be trowelled in, either by hand or using a power float (pan fitted to blades). Stage two is to apply the remainder of the coverage rate and to repeat trowelling. For large floor constructions Tibmix can be spread and trowelled satisfactorily in one stage by mechanical means.
When the surface has sufficiently stiffened (usually about two hours from the first trowelling), a second trowelling should be carried out to close any pores and remove surface undulations. Further treatment may be necessary to remove disc marks and to achieve the final finish required.
All equipment and tools should be rinsed with water immediately after use and then dried.
CURING, HARDENING & SEALING
After final trowelling is complete, Setseal 6 (see appropriate data sheet) should be applied by spray taking care to avoid any puddling.
Appropriate measures must be taken to prevent the surface from drying out too rapidly.
The use of polythene sheeting is not recommended as this can cause blooming of the surface, particularly with coloured Tibmix.
Floor expansion joints should be formed using a polyurethane joint sealant.
Saw cut contraction joints may be filled with a polyurethane sealant or if a harder seal is required a flexible epoxy may be used.
Application of both the Tibmix and Setseal 6 should be carried out in as clean and protected an environment as possible.
