Information
System Structure
Use products mentioned below as indicated in their respective Product Data
Sheets.
Substrate: Fresh concrete slab (See Substrate Quality below)
Dryshake: Manual or machine application of Sikafloor ® -1 MetalTop
Levelling of surface by means of power trowel or laser screed.
Final smoothing with power trowel.
Curing compound: Application of any of the solvent based products in the
Sikafloor® ProSeal or Sikafloor® curehard 24 range.
Application Details
Consumption
~ 7 kg/m2 . This figure does not allow for surface profile and wastage.
Substrate Quality
The concrete deliveries must be of consistent quality.
A concrete slump in the range 75 to 110 mm will normally give best results.
The slab must be of good quality concrete with a minimum water/cement ratio
consistent with the production of a fully compacted slab.
The compressive strength must be a minimum of 25 N/mm2 .
Use of Sikament® or Sika Viscocrete® super plasticisers is advised to ensure the
optimum quality of concrete and where fibres are used, their optimum dispersion
within the mix.
Air Entrained Concrete is not a suitable substrate for the application of dryshake
hardeners.

Application
Instructions
Application Method /
Tools
(i) Mechanical Application - Automatic spreader in conjunction with a laser screed:
Spread Sikafloor® -1 MetalTop evenly onto the concrete immediately after screeding
at 7 kg/m2 in one application.
(ii) Manual application:
Dependent on the conditions, remove the surface “bleed” water or allow it to
evaporate. Sprinkle Sikafloor® -1 MetalTop onto the screeded concrete evenly in
2 stages (first stage: 4 kg/m2 ; second stage: 3 kg/m2 ).
Care must be taken to apply the product without creating ripples etc. in the concrete
surface. Overall application rate 7 kg/m2 . Casting Sikafloor® -1 MetalTop powder
carelessly or further than 2 metres from point of casting will reduce the consistency
of finish.
Compaction:
The first application must be worked into the slab followed immediately by the
application of the second stage quantity of Sikafloor ® -1 MetalTop.
Notes:
- Never add water to the surface where the dryshake has been applied.
- Sikafloor® -1 MetalTop results in the slab surface becoming “stiff” more quickly
than usual. Careful trimming must take place along the edges where adjoining
slabs are to be poured.
- Final finishing to close pores and remove undulations can be achieved either
by hand or powered trowels.
Cleaning of Tools
Clean all tools and application equipment with water immediately after use.
Hardened / cured material can only be removed mechanically.
Application Time
Application time for dryshake products is influenced by every variable which affects
the placing of concrete, and can therefore vary substantially, depending on the
prevailing conditions.
For mechanical application with automatic spreader and laser screed, the spreading
can start almost immediately after the concrete has been levelled to allow for the
hydration of the dryshake. Compaction with the trowel can start as soon as the
weight of the power trowels is supported by the concrete.
For manual application, the dryshake must be spread once the concrete can be
stepped on, without leaving a print deeper than 3 - 5 mm.
Periodical checking of the condition and development of the concrete will determine
the correct time frame for each stage and sequence of application.
Notes on Application /
Limitations
The application of the dry shake powder must not be carried out in strong wind or
draughts.
Do not use concrete where some cement has been replaced by fly ash, as this
makes the mix sticky and less workable.
Variations in concrete characteristics such as water content and cement quality
may lead to slight colour variations.
Dry shake hardeners give a finish to concrete with some colour variation across the
floor due to the natural variability of the concrete onto which they are applied.
To ensure optimum of colour consistency, it is essential that the floor laying
operation is as clean and protected from the environment as possible.
Colour variation during the drying out period is normal for this system and is to be
expected.
Every effort must be made to ensure an even application of Sikafloor® -1 MetalTop.
Correct timing and trowelling techniques are essential.
At low relative humidities (below 40%), efflorescence can appear on the surface.
At high relative humidites (above 80%), bleeding, slower curing and hardening can
occur and extended finishing operations be required.
Slip resistance can be enhanced through chemical ageing. 4

Curing Details
Curing Treatment
Cure and seal Sikafloor® -1 MetalTop immediately after finishing using any of the
solvent based products in the Sikafloor® ProSeal or Sikafloor® curehard 24 range.
(Refer to separate Product Data Sheet). Apply by roller of fine mist spray.
Disperse any excess pools using a roller.
Joints:
After finishing operations and completing saw cuts, clean off any residual saw
lubricant / slurry without delay. Joints can be filled with Sikaflex® PRO-3 WF or
another appropriate Sikaflex® sealant in accordance with the floor design
requirements.
Substrate temperature +10°C +20°C +30°C
Foot traffic ~ 18 hours ~ 12 hours ~ 8 hours
Fully serviceable ~ 10 days ~ 7 days ~ 5 days

for use
The above values are dependent upon the concrete reaching its design strength for
serviceability and will be affected by changing ambient conditions, particularly
temperature and relative humidity.
Cleaning /
Maintenance
Methods
To maintain the appearance of the floor after application, Sikafloor® -1 MetalTop
must have all spillages removed immediately and must be regularly cleaned using
rotary brushes, mechanical scrubbers, scrubber dryers, high pressure washers,
wash and vacuum techniques, etc., using suitable detergents and waxes.
