PU Floor 3D

One-component aliphatic polyurethane binder for decorative flooring

Product Description

PU Floor 3D is a one-component, moisture-curing, non-yellowing, transparent aliphatic polyurethane binder. When PU Floor 3D is mixed with clean, dry natural aggregates at the correct aggregate/binder ratio, it may be used to create surfaces with very high resistance to wear and yellowing. Preparation is very simple and consists of mixing assorted aggregates, such as marble, quartz or natural stone with particle size 2-4 mm or 4-8 mm with PU Floor 3D and then placing the mix to form a multitude of decorative effects. What is more, its excellent resistance to atmospheric agents means it may also be used for external applications, particularly for pervious surfaces. PU Floor 3D also resists the action of the most commonly used de-icing salts.

Field of Application

PU Floor 3D is a one-component, moisture-curing, non-yellowing, transparent aliphatic polyurethane binder. When mixed with natural aggregates, such as marble, natural stone or quartz, it may be used to make pervious floorings for internal and external surroundings. When PU Floor 3D is mixed with monochrome or multi-colored assorted aggregates, it may be used to create unique flooring with an unlimited variety of patterns and aesthetic effects. PU Floor 3D may be used for the following:

· Street furniture, creating decorative surfacing for squares, avenues and sidewalks.

· Decorative resin surfacing for external surroundings such as terraces, balconies, walkways.

· Decorative pervious resin systems around swimming pools.

· Decorative flooring for internal surroundings such as showrooms, department stores and retail outlets.

Application Procedure

Preparation of the substrate

The surface of concrete floors must be dry, clean and sound and have no crumbling or detached areas. The compressive strength of the concrete used for the substrate must be at least 25 N/mm² and its tensile strength must be at least 1.5 N/mm². The strength of the substrate must also be suitable for its final use and the types of load to which it will undergo. The level of moisture in the substrate must be a maximum of 4% and there must be no capillary rising damp. The surface of the floor to be treated must be prepared with a suitable mechanical process to remove all traces of dirt, cement laitance and crumbling or detached portions, and to make the surface slightly rough and absorbent. Before applying the product remove all dust from the surface with a vacuum cleaner. Any cracks must be repaired by filling them with Epoinject, while any deteriorated areas in the concrete must be repaired epoxy mortar. Apply primer as is or mixed with Quartz 0.5 on the substrate after it has been prepared as specified with a straight trowel or a rake. Immediately after applying primer, lightly broadcast the surface while still wet with Quartz 0.5 at a rate of 0.5 kg/m²; we advise against exceeding this consumption rate. Make sure there are no open pores in the surface of the substrate, otherwise air bubbles could escape and form small craters or pinholes in the self-leveling finishing coat.

Preparing the product

Mix PU Floor 3D one-component polyurethane binder with the aggregates selected for the mix natural stone, crushed marble or quartz, particle size 2-4 mm or 4-8 mm at a binder/aggregates ratio of 1 : 20 by weight. Aggregates must be perfectly clean and dry. Mix with a drill at low-speed with a spiral mixing attachment or in a traditional cement mixer.

Applying the product

Pour PU Floor 3D on the surface of the floor and spread it out evenly with a smooth or notched trowel with “V” shaped. Using a notched trowel allows the thickness of the layer and the consumption rate of the product to be controlled more easily. Go over the surface with a spike roller several times while the product is still wet to even out the thickness of the coat and to remove any air entrained into the product during mixing.
