Technical information

• Level IT TOP should not be applied on projects unless it can be guaranteed that subfloor and air temperatures do not drop below 6°C during application and throughout curing (normally 7 days minimum).
• The use of radiant heaters is recommended to attain ideal application temperatures.
• Do not use fuel burning space heaters.
• Light ventilation is recommended, particularly in enclosed areas. Avoid strong draughts as this can cause localised rapid drying and may result in surface crazing.
• Level IT TOP can be applied both by hand mixing of individual units or by continuous pumping.
• Do not use warm water as this will reduce the products working time and may result in shrinkage.

How to apply Level IT Top Heavy Duty

For hand mixing application

1. Pour 4.25 litres of clean cold water into a clean oversized bucket (20+ Ltrs), and then gradually add the powder whilst mixing continually with an electric drill with power whisk.
2. When all powder is added mix for a further 2 mins, keeping the whisk below the surface (to minimise air entrapment), until a lump free creamy material is attained.
3. The product can then be poured onto the floor and, using a smooth steel trowel, spread out to the desired application depth.
4. A spiked roller can be used whilst the product is still fluid to minimise air entrapment and “marry” wet edges together to give a uniform finish.

For pump application

• Follow pump manufacturer’s recommended set up guidelines.
• Ensure the correct water ratio is used by carrying out a flow tube test at the beginning of the project and at regular intervals throughout (ideally once per pallet) to check that ideal flow is being maintained.
• When using an UltraFloor flow tube of capacity 200ml then a flow rate of 250 to 280 mm is acceptable.
• When using other flow tubes we recommend that a single unit be mixed by hand as above and the flow rate of the mixed unit be assessed with the specific flow tube.
• For large projects it is recommended that the area be sectioned off into manageable sized bays where a wet edge can be maintained throughout the pumping process.

Notes regarding joints when applying Level IT Top

• All joints within the subfloor that are designed for movement MUST be followed through to the surface of the Level IT TOP.
• It is recommend that subfloor joints should be marked out prior to applying Level IT TOP and re-established by disc cutting after 24-48 hours.
• It is also recommended that a movement joint also be incorporated at all perimeters, columns and at door threshold to ensure building movement does not result in the Level IT TOP cracking.
