Description Product Overview p>Mapei Mapeprim SP is a two-component, solvent-free primer formulated to enhance the adhesion of smoothing and levelling compounds on difficult, non-absorbent substrates. Once mixed, it creates a uniform, tacky film that promotes reliable bonding for subsequent floor preparation systems. It is specifically designed for use over smooth and compact surfaces such as ceramic tiles, natural stone, timber, metal, and existing coatings where traditional primers may struggle to achieve adequate adhesion. Mapei Mapeprim SP is commonly used in flooring preparation prior to applying levelling compounds, ensuring consistent performance across a wide range of substrates. Key Features Two-component solvent-free primer Designed for non-absorbent and difficult substrates Improves adhesion of smoothing and levelling compounds Creates a tacky, keyable surface for overlays Low consumption rate for efficient coverage Suitable for a wide range of substrate types Water-dispersed formulation with no flammability concerns Consistent performance across renovation and new work Applications Priming ceramic tiles, natural stone, and polished surfaces Preparation of timber, metal, and painted substrates Use prior to levelling compounds such as Ultraplan or Planolit Priming gypsum and anhydrite substrates Surface preparation for cementitious flooring systems Renovation work over existing finished surfaces Notes Mix Part A and Part B in a 1:1 ratio until uniform colour is achieved Apply using brush, roller, or smooth trowel Apply evenly to avoid pooling or excessive build-up Workability time approximately 1 hour Apply levelling compound while primer remains tacky (1–3 hours) Do not apply on damp substrates or where rising moisture is present Ensure substrate is clean, dry, and structurally sound Do not exceed 24 hours before overlay application Technical Information Technical Specifications: Type Two-component solvent-free primer Components Part A (blue liquid), Part B (white liquid) Mix Ratio 1 : 1 (A:B) Consistency Fluid liquid Pot Life Approx. 1 hour Waiting Time 1 – 3 hours before levelling compound Application Method Brush, roller, or smooth trowel Consumption Approx. 0.1 – 0.2 kg/m² Substrates Tiles, stone, timber, metal, gypsum, concrete Application Temperature 5°C to 40°C Packaging 4 kg (2 2) and 8 kg (4 4) kits Shelf Life Approx. 12 months (sealed, frost-free) This primer is designed for professional flooring applications where strong adhesion over non-porous substrates is critical. Its two-component formulation ensures consistent bonding performance across both renovation and new installation environments.
