Application Guide
- 1. Confirm the substrate is suitable and dry. Do not apply Mapeprim SP to damp substrates or areas subject to rising damp.
- 2. Remove oil, grease, loose plaster, laitance, paint residue and any other material that may impair adhesion.
- 3. Combine Component A and Component B in equal proportions and mix until the colour is homogeneous. Use the mixed primer within approximately 3 hours at +23°C.
- 4. Apply approximately 100–200 g/m² by brush, roller, rubber float or smooth trowel, adjusting consumption to substrate texture and absorption. If required for workability, dilute with approximately 5–10% clean water.
- 5. Allow the primer to turn transparent while remaining tacky. Under the TDS reference conditions, this normally occurs after approximately 1–3 hours.
- 6. Apply the compatible smoothing compound or cementitious mortar while the primer remains tacky and within 24 hours.
- 7. Wash tools, containers and affected clothing immediately with clean water before the material hardens.
