UltraFloor Level IT Base: Heavy Duty

For a quick-setting and hardening smoothing underlayment for internal floors, buy the UltraFloor Level IT Base: Heavy Duty.

This heavy duty, deep-fill smoothing underlayment has a high-compressive strength and comes in a single 25kg bag. It is incorporated with recycled raw materials.

You can mix and apply this Level IT Base as single units. Either a pump or trowel can be used to apply this rapid setting underlayment, and is especially the ideal choice with pumping applications. Level IT Base is particularly suited for projects on the larger side.

A 25kg bag of UltraFloor Level IT Base will cover approximately 3-metre² when using a thickness of 5mm. However you can apply this product at a thickness of 5-50mm. It is also moisture tolerant.

As a quick-setting and hardening product, you have an application time of 30-40 minutes. And after just three hours the underlayment will have dried enough that you can walk on the area – it is that rapid.

UltraFloor Level IT Base is ideal to use with UltraFloor’s Level IT Top which provides a heavy-duty abrasive resistant surface finish to your floorings also comes in 25kg bags.

Summary of features – UltraFloor Level IT Base: Heavy Duty

  • Rapid-setting and hardening
  • High compressive strength
  • Tolerant to moisture
  • Apply using a pump or trowel
  • Application time: 30-40 minutes
  • Walk on after 3 hours
  • Coverage: approx. 3 metre² at 5mm thickness
  • Can apply 5-50mm thickness
  • Use for internal floors
  • Ideal to use with Level IT Top
  • Size: 25kg bag

Technical information

  • Level IT BASE should not be applied on projects unless it can be guaranteed that subfloor and air temperatures do not drop below 6oC during application and throughout curing (nominally 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 locallised rapid drying and may result in surface crazing.
  • Level IT BASE 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 mix and apply Level IT Base

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 the 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. When applying at thicker sections a long handled float or dapple bar is preferred.
  5. 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. The depth of spike must be a minimum of 30% longer than the application depth of product otherwise it will not be able to rotate in the product. This is particularly important in deeper applications (15mm +).

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.
  • We recommend the logging of flow test results, site conditions, batch numbers and pump equipment for future reference.
  • When using an Ultra Floor 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.
