Mapei Mapefloor Finish 52W

Mapei Mapefloor Finish 52W is a two-component, low yellowing, polyurethane finishing compound specially formulated to form a transparent, opaque, wear-resistant protective finishing coat on Mapei epoxy products.

Best Uses

Compatible with Mapei floor products such as Mapei Mapefloor I 300 SL and Mapei Mapefloor I 500 W. This product is 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.

Application

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.

For Resin Coatings: Mapefloor Finish 52 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.

For 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.

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.
