TIBMIX 700 is designed to be applied onto freshly laid concrete floors, producing a very dense, tough, abrasion and impact resistant monolithic surface that significantly extends the service life of industrial concrete floor.
TIBMIX 700 is available in 25 kg double-layered sacks, 1500 kg (60 sacks) on a pallet.
Pallet dimensions are 1000 x 1200 mm.
General recommended dry shake floor hardener application rate for concrete floors is 3 - 5 kg/m² - please contact our Technical Department
The material does not lose any of its designed properties for at least 24 months if stored properly at temperatures between 5°C and 30°C.
TIBMIX 700 has a shelf life of 9 months from date of manufacture if stored at good conditions in its original unopened sacks. Keep away from freezing temperatures and moisture.
Recommended compressive strength of the concrete floor mix should be at least 25 MPa (cube), with a workability (slump) of S3 (100 - 150 mm) or S4 (160 - 210 mm). Use of super-plasticizers is highly recommended – this adds to the workability of the mix and reduces shrinkage-related early stresses and crack development. The required properties of a concrete mix should be agreed in advance with the concrete plant.
A "foot print method" is preferred to determine the proper time to start dry shake application. Careful walking should leave a 3 - 4 mm foot print into the concrete surface. Before dry shake hardener is spread, any bleed water should be removed and surface trowelled with pans to open the pores and to prepare for maximum dry shake bonding.
Dry shake floor hardener should be spread in two layers (60 - 65% and 35 - 40%), trowelling each layer with pans after the material has picked up moisture from below (dry shake will darken). Application rate of 3 kg/m² per layer is not recommended to be exceeded, unless large spreader machinery is used. While 2 - 3 kg/m² can be applied to suppress steel fibers, 3 - 5 kg/m² is required to increase wear and abrasion resistance of the surface. Coloured dry shakes may require higher application rate to produce a smooth shade (6 - 8 kg/m²).
When the surface has set enough, final power trowelling with blades will give the concrete floor the required finish.
Stainless steel blades are recommended for the trowelling of light coloured dry shakes. Avoid "burning" the surface which may lead to flaking or even delamination of the dry shake.
The concrete floor surface should be sealed and cured immediately after final trowelling with the curing aid Setseal 6. Keep the application rate at 0.08 - 0.1 litre/m² and avoid slops. Setseal 6 protects the concrete surface from rapid evaporation, thus DCP Technical Department making it less prone to cracking and surface flaking, and also increases surface abrasion and resistance to dirt, water, oils and other chemicals.
Joints should be cut 24 - 48 hours after final trowelling and filled with joint filler after 1 - 3 months (when joints have fully expanded)
All tools and equipment should be cleaned immediately after finishing by water and dried.
HEALTH AND SAFETY
TIBMIX 700 contains cement that powderers into very fine dust when thrown or blown in the air. In contact with moisture or water, cement undergoes an alkali reaction which irritates eyes, mucous membranes and skin. Avoid material contact with eyes, mouth, skin and food.
In case of accidental contact with skin or eyes, rinse with plenty of water and seek immediate medical advice.
In case of ingestion, seek immediate medical advice.
Exposure to cement could produce allergic reactions and long-term effects. Proper safety measures must be maintained working with materials containing cement – use gloves, respirators, protective goggles or masks.
