MAPEI Planitop 400 Rapid-Set Repair Mortar R3 1-40mm 25kg

MAPEI Planitop 400 25 kg – fast-setting repair, modeling and slope mortar R3

Planitop 400 is a non-slump, shrinkage-compensated and fast-setting repair and modeling mortar for indoor and outdoor use. It meets the requirements of class R3 (type CC) according to EN 1504-3 and can be subjected to loads after approx. 4–5 hours – ideal for quick repairs, coves and small-area slope screeding.

Thanks to fine aggregates (maximum grain size 0.5 mm), it can be used in layer thicknesses from 1 mm to 40 mm – even as a fine filler.

Scope of delivery: 25 kg paper bag, individually or as a pallet with 40 bags. Color: gray.

Advantages of Planitop 400

• Fast-setting – load-bearing after approx. 4–5 hours
• Layer thickness 1 to 40 mm per application
• Non-slump and shrinkage-compensated
• High adhesion and high mechanical strength (compressive strength > 35 MPa)
• Can be used as a fine filler in the 1 mm range
• Class R3 according to EN 1504-3, non-combustible (A1)

Typical areas of application

• Repair of balcony parapets and edges in case of reinforcement corrosion
• Reprofiling of corners, concrete beams, columns and slabs
• Repair of precast concrete elements and concrete pipes
• Formation of coves prior to waterproofing work
• Small-area slope screeding at drains on balconies and terraces
• Filling of blowholes and honeycombs

Consumption

Consumption is approx. 1.85 kg/m² per mm of layer thickness. A 25 kg bag is therefore sufficient for approx. 13.5 m² at 1 mm or approx. 2.7 m² at 5 mm layer thickness, for example.

Processing of Planitop 400

1. Prepare the substrate

The substrate must be clean, solid and load-bearing. Remove loose areas down to the sound core concrete, expose corroded reinforcement, remove rust to Sa 2½ standard and coat twice with Mapefer or Mapefer 1K. Pre-wet absorbent surfaces until saturated and allow to dry to a matt-damp state – do not apply to shiny wet surfaces.

2. Mixing

Add 3.75–4.0 l of water first and mix the powder in without lumps using a slow-speed mixer (max. 400 rpm) while stirring continuously. Due to the short pot life, only mix as much as can be processed in approx. 10 minutes. For layer thicknesses over 10 mm, add 20–25% quartz sand (2–4 mm) according to the manufacturer.

3. Application

Apply with a trowel or spatula, maximum 4 cm per application. A second layer can be applied after approx. 15 minutes. Smooth the surface, e.g., with a trowel.

4. Aftercare

Protect from drying out too quickly for at least 24 hours and protect from sun, frost and wind during and after application.
