Description

Fosroc Nitoproof 410 Internal Waterproofing Membrane is a water-based, fast-drying, flexible, two-component, polymer-modified cementitious waterproofing membrane for use under trafficable floor finishes in internal wet areas.

Scope

1. Fosroc Nitoproof 410 has been appraised for use internally under trafficable floor finishes within the following scope:

• on floor substrates of concrete, plywood, fibre cement compressed sheet and fibre cement sheet tile underlay, and on wall substrates of concrete, concrete masonry, cement render, wet area fibre cement sheet lining systems and wet area plasterboard lining systems; and,
• when protected from physical damage by trafficable floor finishes; and,
• where floors are designed and constructed such that deflections do not exceed 1/360th of the span.

2. The use of Fosroc Nitoproof 410 on concrete slabs where a hydrostatic or vapour pressure is present from below is outside the scope of this Appraisal.

3. Movement and control joints in the substrate must be carried through the membrane and trafficable floor finish. The design and construction of the substrate and movement and control joints is specific to each building and is therefore the responsibility of the building designer and building contractor and is outside the scope of this Appraisal.

4. The trafficable floor finishes are outside the scope of this Appraisal.

5. The membrane must be applied by Fosroc trained and approved applicators.
