Shumoplast
Shumoplast sound-insulating leveling coating is applied in soundproof floor structures of a floating type as a leveling elastic layer below the screed over uneven monolithic, prefabricated, or combined structural floorings. Request PriceInnovative Sound-insulating Leveling Coating
Shumoplast is a pelletized polymerizable material made from expanded polystyrene which acts as an elastic sound-insulating layer in “floating” type floor structures.
Levels Unevenness of Floorings
Pelletized mixture eliminates local overflows, cracks, and cavities on the flooring surface , covers fine particles of construction waste as well as reinforcement protrusions and burrs.
Engineering Utility Lines may be Located Inside the Shumoplast Layer
Shumoplast can be used in premises with a large number of engineering utility lines.
Electric wiring, heating system pipes, water supply lines, and other utilities may be placed inside the Shumoplast layer.
Quick Installation without Preliminary Floor Leveling
Shumoplast pelletized mix may be easily, quickly, and uniformly applied on the floor surface with the use of a conventional float trowel.
The material does not need any pre-cutting and excludes waste and cut-offs.
Features
Shumoplast plays the role of an elastic sound-absorbing layer in the soundproofing "floating floor" design. Before applying the Shumoplast sound-insulating leveling compound, make sure that the local unevenness of the floor and the size of construction debris do not exceed 10 mm (0.4 in). Before installation of screed, it is necessary to wait for complete polymerization of the 20-mm (0.8 in) thick mix for 48 hours at a temperature no lower than 15°С (5 °F). A leveling screed with a thickness of at least 60 mm (2.4 in) is laid directly on the Shumoplast coating and must necessarily be reinforced with metal structures for increased mechanical strength.
Maintenance info
Composition and description of Ultrakustik Floor Plast
Shumoplast sound-insulating leveling coating is a ready-for-use mixture of an elastic vibration insulation material.
It is made of polystyrene foam pellets, Indian rubber, and acrylic binder developed using an innovative formula.
- Shumoplast is not a matrix for development of bacteria, mold, and other harmful microorganisms ensuring safety and durability
- Shumoplastt practically does not adsorb moisture and does not require any additional waterproofing
Storage and Transportation
Shumoplast can be transported by any means of transport. Transportation at subzero temperatures is allowed, provided that there are no more than three cycles of freezing-thawing.
A package of the Shumoplast pelletized mixture should be stored in warm, dry enclosed premises in a packed form.
When in storage, Shumoplast boxes should be placed on wooden pallets, boards, or other padding materials to avoid sagging.
Features of the material usage
Shumoplast sound-insulating leveling coating is a ready-to-use pelletized mix of elastic vibration insulating material which, after being applied on the flooring surface, performs the function of soundproofing lining under the leveling screed in the “floating floor” structures.
Before installation of a coating with a standard thickness of 20 mm (0.8 in), all debris with a fraction size of more than 10 mm (0.4 in) shall be removed from the flooring surface.
The 15-30 mm (0.6 – 1.1 in) thick coating is applied directly onto the flooring manually or mechanically.
The material is compacted to the required thickness using a polyurethane float trowel. The time of complete polymerization for a 20-mm (0.8 in) thick layer is 48 hours at a temperature no lower than 15°C (5 °F).
