Mira 4400 multicoat is a ready-mixed polymer based membrane which is easy to apply and distribute on surface all floor and wall substrates in wet room.
Product description
Highly elastic, polymer based waterproofing membrane.
Ready to use - do NOT dilute. Easy to distribute on surface.
Application areas
Use 4400 multicoat as waterproofing membrane on wall and floor surfaces, at wall/floor junctions, corners, joints between boards and panels, and pipe penetrations.
Do NOT apply in swimming pools etc. with water column pressure.
Type of substrate
Waterproofing membrane can be used on substrate of concrete, lightweight concrete, waterproof screed, brick, render, gypsum/wooden based boards and gypsum blocks. Waterproofing membrane can be used on newly cast concrete.
Pre-treatment of substrate
Ensure substrate has carrying capacity, is stable, coherent, cleaned for dust, grease and cement laitance. The substrate
shall be dry. Absorbent substrate shall be primed with 4180 primer. Relative humidity of the substrate should be less than 90%.
Preparation
4400 multicoat is usually not stirred. 4400 multicoat is thixotropic and loses its consistency by stirring. If it is necessary
to stir mixture it must be done with gentle movements and mixture must then rest until normal consistency is achieved
before applying. With vigorous stirring you risk making air bubbles in mixture which may cause fine holes in finished
membrane
For more detailed application instructions, please consult the Mira Waterproofing Instructions in the "Download" tab.
Further surface finish can be applied after 6-12 hours at 18°C.
Follow applying instructions of wet room constructions with ceramic tiles.
