PRi COAT LASTICK
Eco-friendly, two-component, elastomeric acrylic modified, cementitiousmembrane for flexible waterproofing with high levels of adhesion and durabilityof surfaces before fixing with adhesives, ideal for use in GreenBuilding. LowCO2 emissions, can itself be recycled as an inert material at the end of its life.
PRi coat lastick creates a water-resistant layer on balconies, terraces andshower cabinets before fixing tiles, even over existing coverings, doing awaywith the need for costly demolition work.
PRi COAT LASTICK
Preparation
PRi coat lastick is prepared by mixing component A with component B (present ratio of 2 : 1 in the packaging). The two components should be mixed with a suitable low-rev electrical mixer for approximately 2 minutes until a mixture with a homogenous consistency is obtained. Pour the latex into a clean recipient and gradually add the powder during the mixing operation. Leave the mixture to rest for approximately 2 minutes to allow the co-polymer to become completely dispersed and
mix again for approximately 20 seconds before use.
Application
PRi coat lastick should be applied to a previously prepared surface with a synthetic brush, plain trowel or roller. When waterproofing, apply the first coat and when the product has hardened apply the second coat in a direction transversal to the previous coat creating a minimum total thickness of 1 mm. PRi coat lastick layers must be laid with great care to ensure the surface is covered with no voids. Subsequent fixing of the covering must take place at least 24 hours after application of the last waterproofing coat, in the case of low temperatures and high humidity levels the waiting time before fixing must be extended.
Cleaning
Product residues can be removed with running water before the product has hardened.
• High adhesion to absorbent and non-absorbent substrates
• High compatibility with cement-based adhesives
• Breathable
• High workability
• Floors and walls, for internal and external use
• Suitable for overlaying
•High Crack Bridging
Waterproofing of balconies, terraces, kitchens, saunas, Turkish baths, showers before coverings in ceramic, glass mosaic and stonematerials are fixed.
Suitable for:
- concrete
- ement-based screeds/plaster
- old flooring that is dimensionally stable and anchored to a ceramic substrate
- natural stone
Do not use
Do not use on metal or wooden substrates, on bituminous coverings, to waterproof surfaces that are to be walked on and uncovered swimming pools, on lightened screeds.Do not use on metal or wooden substrates, on bituminous coverings, to waterproof surfaces that are to be walked on and uncovered swimming pools, on lightened screeds.
Preparation of substrates
- The surface must be perfectly cured and dry, solid (i.e. free of weak or easily removable parts) and free from oil, grease, paint andde-bonding agent. When working on weakened parts, when parts of the substrate are missing and also in the
case of honeycombs,the substrate must be restored with suitable repair mortars. Uneven areas must be corrected with suitable smoothing and finishingproducts. On ceramic substrates all traces of surface treatments such as wax and oil must be removed. Before application dampabsorbent surfaces without letting any stagnant water. - For external and internal angles and for water and drainage pipeline crossings use special pre-formed pieces applied using PRi coat lastick. Waterproof the structural joints with appropriate systems and arrange for continuous waterproofing..
