MasterSeal® NP 474 is a single component polyurethane based sealant for floor & walls joints with excellent resilience and pick resistance. It cures under the influence of atmospheric humidity and forms an elastic, chemical resistant joint sealant with excellent mechanical properties.
Forms a smooth blister free surface, only when applied onto dry substrates.
No thermo plasticity (no temperature softening).
Good weathering and aging resistance.
Fast skinning time. Low risk of dirt pickup. No residual tackiness
Application
Interior and exterior application.
Connection and expansion joints in buildings and civil structures.
Pedestrian and traffic areas (e.g. car decks/parks) Warehouse and production areas.
Ceramic tile coverings exposed to traffic (e.g. public areas, shopping centers).
Expansion and construction joints in water management, e.g. water transport channels
Areas constantly submerged in water.
Dosage
The consumption depends on the size of the joint. Consumption can be calculated as follows: Joint width (mm) x Joint depth (mm) = ml of product / linear meter of joint. Example; 10 mm x 10 mm joints: approx. 100 ml/m.
