Features & Benefits

• Specially formulated to form a transparent, opaque, wear-resistant protective finishing coat on epoxy products, such as Mapefloor I 300 SL and Mapefloor I 500 W
• Particularly suitable as a primer for Mapefloor Finish 58 W on cementitious systems such as Ultratop, Ultratop Living and Ultratop Loft and as a dust and oil repellent treatment for concrete and natural-finish concrete floors, without leaving the surface with a “wet-look” finish
• Thanks to its penetration properties when applied on cementitious substrates, Mapefloor Finish 52 W may also be used for protecting concrete structures subject to light attack by chemical agents
• Solvent-free, two-component, low-yellowing polyurethane finishing product in water dispersion, produced according to a formula developed in MAPEI’s own R&D laboratories
• Once dry, Mapefloor Finish 52 W does not significantly modify the colour of the surface treated. This characteristic is particularly advantageous when the original appearance of the surface to be treated needs to remain unchanged
• Applied using a roller or the airless spray system, at a thickness of 60 to 100 microns
• When applied on absorbent cementitious substrates, Mapefloor Finish 52 W is used to even out the absorbency of the surface before applying the final treatment of Mapefloor Finish 58 W

Preparation

Resin coatings: Mapefloor Finish 52 W may be applied on both new and old resin coatings.If the product is applied on new resin coatings, the said coating must be perfectly hard, dry and must have been laid no more than 24 hours before. If the recommended maximum time of 24 hours is longer, the surface must be sanded down using a single-headed sander with fine (80-100 grade) sandpaper or abrasive mesh, in order to guarantee that the product bonds well.

If Mapefloor Finish 52 W is applied on old resin surfaces, they must be perfectly clean and free of oil, greasy substances and any other product which could affect bonding. Also in this case, the entire surface must be sanded down to guarantee that the product bonds well to the substrate.

Ultratop, Ultratop Living, Ultratop Loft and concrete surfaces: Surfaces in Ultratop, Ultratop Living or Ultratop Loft which are to be treated with Mapefloor Finish 52 W must be perfectly hard. According to the temperature and thickness of the surface, wait at least 48 hours before applying Mapefloor Finish 52 W. Sand the surface and immediately remove the dust. Wash the floor and leave it to dry before carrying out the impregnation treatment.

Concrete surfaces must be solid and perfectly clean. Remove any traces of dust, grease and form-release compound before applying the finishing treatment.

Mapefloor Finish 52 W is a polyurethane-based finishing product made up of two pre-dosed components. To prepare the product, pour component B into the container with component A and mix well with a low-speed drill with a blending attachment until a homogenous mix is obtained.

On absorbent surfaces, such as concrete, Ultratop, Ultratop Living or Ultratop Loft, the product must be diluted with 1:1 by weight of clean water

Application

• Apply Mapefloor Finish 52 W uniformly using a smooth-haired roller or the airless spray system on resin coatings. When used as a primer on the surface of Ultratop, Ultratop Living and Ultratop Loft, spread the product over the surface with a wax mop
• If a non-slip finish is required add Mapefloor Filler while mixing slowly and continuously at a ratio of 3-5% in weight
• We recommend applying the product immediately after mixing to avoid the Mapefloor Filler settling
• Tools and equipment used to prepare and apply Mapefloor Finish 52 W must be cleaned with plenty of running water immediately after use. After hardening, the product may only be removed using mechanical means
• Coverage 50-150 g/m² per coat, according to the characteristics of the substrate.

Limitations

• Do not apply Mapefloor Finish 52 W on dusty, crumbling or irregular substrates
• Do not apply Mapefloor Finish 52 W on surfaces which are wet or which have oil or grease stains
• When applied on dark coloured non-cementitious substrates white light streak may appear
• Carry out preliminary tests beforehand
