Ultraplan Marine 900

Lightweight, Fiber-Reinforced, Quick-Setting, Self-Leveling Underlayment

Ultraplan Marine 900 is a lightweight, fiber-reinforced, quick-setting, self-leveling underlayment for interior decks. It can withstand light foot traffic after 2 to 3 hours and rubber-wheel traffic after 3 days. Thanks to MAPEI’s High-Hydrated Cement Technology (HCT™), Ultraplan Marine 900 offers superior drying-out characteristics for quick curing and does not contribute to efflorescence.

Application

1. Pour approx. 5.7-6.0 litres of clean water into a clean container large enough to hold the mix. Pour a 15 kg bag of Ultraplan Marine 900 into the water while mixing and keep mixing with an electric mixer at low-speed to form a smooth, lump-free, self-levelling mix.

2. Prepare larger quantities of Ultraplan Marine 900 in a mortar mixer. Leave the mix to stand for 2-3 minutes, mix again and spread the mortar within its specified open time. The open time of the mortar will be shorter if the temperature is higher than +23°C. It is good practice to only mix quantities of Ultraplan Marine 900 that will be used within 30-40 minutes. Spread a single layer of Ultraplan Marine 900 from 3 to 20 mm thick over Eco Prim Marine with a metal trowel.

3. Check the consumption rate of the product during spreading to make sure the thickness required is applied. Ultraplan Marine 900 may also be applied with a rendering pump.

If a second layer is required, we recommend waiting until the first one has set to foot traffic (approximately 3 hours at +23°C and never more than three hours after the set to foot traffic time). If this time limit is exceeded, another coat of Eco Prim Marine must be applied beforehand to help adhesion. Various types of floor covering may be applied to Ultraplan Marine 900. Always adhere to the specified recoating time of the product (at +23°C and 50% R.H, refered to the maximum applicable thickness) : ▪ 3 days for resilient, textile, resin-based and wood coverings ▪ 1 day for ceramic coverings These times vary depending on the thickness of mortar applied, the surrounding temperature and the level of humidity in the environment. It is recommended to check the level of residual moisture in the hardened layer of mortar to make sure it is compatible with the floor coating or dressing to be applied.

In case of resin floor coverings, a layer of Mapedeck Epofloor mixed with 20-30% by weight of quartz (particle size depending on the desired thickness) must be applied with a smooth steel trowel on a duly prepared and dust-free surface. Then sprinkle quartz with a particle size of no more than 0-0.5 mm onto the product while it is still fresh to saturation. If the mortar needs to be applied over several days, it is necessary to create suitable joints with a twocomponent epoxy product (i.e. Mapedeck Epofloor).
