Osmotic two-component type weatherstrip adhesive cement

Code: OSM.0083

Components: 2

Appearance: Powder + Liquid

Two-component adhesive cement for interior and exterior use, based on hydraulic binders, modifying and flexibilising resins, selected siliceous aggregates, for the preparation of adhesive mixtures, easy to spread, with high deformation capacity and watertightness. Perfect for bonding coatings even low absorption, on cement surfaces with low porosity (for example interior coverings for swimming pools).

Use from 5 to 6 kg/m² of OSMOKOLL depending on the type of support and the type of material to be bonded.

Use fields

Bonding tiles, waterproofing and anti-humidity coatings, structures and masonry exposed or underground provided they are sufficiently porous and absorbent and free from any waterproofing and / or water-repellent surface treatment, whether chemical (siloxanes, epoxies, polyurethanes, etc.) or natural (wax-up). Bonding small vitreous tiles for swimming pools. Bonding tiles on OSMOCEM FLEX or OSMOCEM D type osmotic coatings on terraces and balconies.

Preparation of supports

Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., water repellent treatments in general, etc. conveniently saturated with water until they reach the condition "saturated with dry surface".

Use method

Mix the powder component (component A) with the hydrating solution (component B) with a drill at a low number of revolutions, pouring the powder progressively in the liquid, continue mixing until a homogeneous lump-free mixture is obtained. After mixing is completed wait a few minutes and stir again before proceeding with the application.

Application methods

- Notched finishing trowel

Tool cleaning

- Water

Permitted supports

- Concrete

- Tiles

- Floor screed

Warnings, precautions and Ecology

It is always essential to carry out preliminary tests to verify the appropriateness of the product, depending on specific requirements.

Do not apply in case of direct exposure to sunlight and cure the protection and moist hardening.
Do not apply on little or non-porous substrates or previously coated with water-repellent treatments in general, if not after appropriate roughening by bush hammers, sanders and equipment suitable for preparatory treatments of substrates, or after appropriate treatment with suitable polymeric primers.
