İsonem MS 80 – Transparent Exterior Waterproofing Preserving the Natural Appearance
Breathable transparent exterior waterproofing that preserves…
PRODUCT DESCRIPTION
İsonem MS 80 is a siloxane-based transparent waterproofing product that protects absorbent exterior surfaces without altering their appearance or texture. Since it does not form a surface film, it preserves the natural breathability of the building or natural stone and maintains its original look. It does not cause darkening, blistering, or surface gloss.
Thanks to its high alkali resistance, it can be safely applied on both new and old concrete surfaces. It helps prevent efflorescence and staining caused by mortar on pressed brick, natural and artificial stone, and plastered surfaces. By preventing water penetration, it helps maintain the thermal insulation performance of building elements. It also protects structures against rain-induced erosion and corrosion, thereby extending the lifespan of buildings.

Surface Preparation – İsonem MS 80
The surface must be dry, sound, and completely free of any dirt, oil, dust, or other contaminants that may reduce adhesion. Do not apply on wet surfaces; ensure the substrate is fully dry. Any old coatings, residues, or weak layers that may reduce absorbency should be removed. Cracks larger than 1 mm must be repaired using suitable repair products before application.
Application Method
Apply the product from top to bottom using a brush, roller, or spray, in at least two coats. The second coat should be applied wet-on-wet before the first coat fully dries to ensure complete penetration and saturation of the surface. Do not use flammable materials during application. Avoid contact with eyes and skin; protective gloves and goggles are recommended.
Consumption – İsonem MS 80
-
Depending on the surface absorbency, approximately 100 – 200 mL/m² is required.
Coverage Area:
-
A 3.5 L can covers approximately 17.5 – 35 m², depending on surface absorbency.
