TIBMIX 500 can also be used to suppress steel fibres in concrete floors. When troweled into freshly laid concrete, TIBMIX 500 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.
Abrasion resistance conforms to EN 13892-4 AR0,5 (Special Class).
TIBMIX 500 should be used in conjunction with Setseal 6 polymer curing membrane/sealer/hardener.
Coloured versions of TIBMIX 500 are also available which contain a high quality, durable pigment.
TIBMIX 500 is available in 25 kg bags.
Recommended application rate of 3-5 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.
12 months in unopened bags stored under good conditions.
The base concrete should be a minimum grade C30/37 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 maximum 0,55 and 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 500.
Broadcast the TIBMIX 500 evenly over the surface of the base concrete. Where manual troweling is involved, application in two stages is recommended. The first stage should be to apply two thirds of the coverage rate of TIBMIX 500 following removal or evaporation of surface bleed water. Immediately after this stage TIBMIX 500 should be troweled 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 troweling. For large floor constructions TIBMIX 500 can be spread and troweled satisfactorily in one stage by mechanical means.
When the surface has sufficiently stiffened (usually about two hours from the first troweling), a second troweling 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 troweling 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 colored TIBMIX 500.
Floor expansion joints should be formed using Flexseal PU440 polyurethane joint sealant.
