Coverage calculator
How much you need.
The arithmetic uses Mapei's published consumption for Planiseal 88 and the pack sizes we stock. Set your own wastage allowance.
The figures behind it.
- approx. 1.5 kg/m2 per mm of thickness.
Consumption on site depends on the substrate, the tool and the applicator, which is why wastage is yours to set. The result is a quantity to plan and quote with, not a guarantee of coverage. Confirm the system against the current Mapei technical data sheet before ordering.

Where it is not the right product.
- Do not use Planiseal 88 for solving internal condensation problems (use de-humidifying renders, improve ventilation to the area or provide adequate insulation)
- Do not use on plasters, plasterboards, painted walls, plywood, chipboard, asbestos cement
- Do not use on surfaces subject to dynamic stresses
- In no case should Planiseal 88 be applied to a substrate that shows signs of standing water on the surface
- Even though Planiseal 88 is resistant to abrasion and wear from solids normally present in liquids flowing in hydraulic structures, it must not be exposed to traffic
