Mapeprim SP is a primer consisting of two components (A+B). After accurate mixing, application to the substrate, and drying, Mapeprim SP hardens to a compact film resistant to water and ageing.
Mapei Mapeprim SP is ideal for preparing smooth and compact cementitious floors and for levelling existing ceramic tile and natural stone surfaces when used with Mapei smoothing compounds, such as Mapei Ultraplan or Mapei Planolit. Also ideal for the preparation of anhydrite, magnesium, and gypsum surfaces before smoothing or before laying ceramic tiles. Suitable for the preparation of cast asphalt, wood, chipboard, metal sheeting, PVC, painted surfaces.
The substrate must be dry, clean, free from oil, grease, paint residue, loose plaster and laitance. Mapeprim SP should not be applied when the substrate is damp or subject to rising damp. Mapeprim SP is composed of two prepackaged components (A+B), of different colours (light blue and white), which must be mixed in equal proportions to obtain a homogeneous colour. Use the primer within 3 hours of mixing.
Mapeprim SP can be applied with a brush, roller, rubber float, or smooth trowel in an amount varying from 100 to 200 g/m2, according to the degree of absorption and texture of the substrate. To improve workability, Mapeprim SP can be diluted with approx. 5-10% water. Before applying the smoothing compound or the mortar, wait until the primer has turned transparent but remains tacky. Dependent on the type of substrate, temperature, humidity and ventilation on site, drying occurs in approx. 1-3 hours. However, waiting longer than 24 hours is not recommended.
