Adesilex PA synthetic resin-based wooden floor adhesive
Adesilex PA synthetic resin-based wooden floor adhesive: Adesilex PA is a single part adhesive based on synthetic resins, can be used for bonding small sized solid, wood block, strips and engineered wood flooring. Can be applied on most types of substrates including heated. Adesilex PA has excellent sound reduction properties, long working time, "low slump" properties and high tensile strength.
Characteristics and Advantages:
- one-component, easy to handle;
- good adhesion to almost all substrates and timber materials;
- firm texture – retains trowel pattern;
- water-free – no wood swelling;
- very high final strength;
- risk of cracks minimized;
- suitable for underfloor heating;
- rapid initial bonding strength;
- versatile usage;
- splashed material can be easy removed.
- Adesilex PA is available in 16-kg buckets.;
Use Adesilex PA for bonding:
- parquet in strips or mosaic;
- any type of wood flooring in small sizes;
- prefinished parquet in small sizes
- anhydrite and asphalt screeds;
- cementitious screeds;
- wood underlayments;
- chipboard and masonite panels;
- underfloor heating systems;
- Mapecem, Topcem and Topcem Pronto screeds.
Adesilex PA is a rapid-setting synthetic resin-based adhesive in alcohol formulated in a thixotropic, easy to trowel paste of a light wood colour.
Adesilex PA does not contain water and by the solvent evaporation it forms a film with high bonding strength and flexibility and absorbs the normal thermal and hygrometric movement of wood over the substrate.
- Do not use Adesilex PA for wooden planking and large size pre-finished wood sections (use Lignobond instead).
- Do not use in areas that are extremely cold: the area should be heated in winter.
- Do not use over screeds if rising damp is present (install a vapour barrier between the ground and the screed).
- Do not use in open areas without doors or closings.
- Do not use if the wood has a moisture content incompatible with the environmental humidity.
- Do not use if the screed is not dry or if the moisture content is higher than that recommended by the flooring manufacturer (check the moisture content throughout the entire thickness).
- Do not use if the walls and ceilings in the area are not completely dry.
Preparing the substrate:
The substrates must be dry, flat, sound, free of dust, loose particles, cement laitance, varnish, wax, oils, rust, and gypsum residues.
The moisture content must be as recommended by the flooring manufacturer.
Check the moisture content throughout the entire thickness of the substrate with an electric or carbide hygrometer, keeping in mind that the latter gives only approximate values.
For forming fast-drying cement screeds with controlled shrinkage use Mapei’s special hydraulic binders: Mapecem, which enables flooring to be installed after 24 hours and Topcem after 7 days.
Floating screeds over insulation or light-weight layers (eg. light-weight concrete) and concrete slabs on grade must be provided with a vapour barrier to prevent rising damp.
Weak concrete on screed surfaces must be removed or, where possible, consolidate with Prosfas or Primer EP.
Cracks or crazing should be repaired with Eporip.
If levelling is needed use Ultraplan or Nivorapid levelling compounds with high mechanical strength for thicknesses not lower than 3 mm.
For thicknesses over 15 mm, use Planicrete mixed with appropriately graded sand and portland cement, or Ultraplan Maxi.
Very absorbent cementitious or anhydrite substrates must first be primed with Primer PA. Asphalt surfaces need not be treated.
Spreading the adhesive:
Before applying, stir the Adesilex PA in the bucket thoroughly, then apply it on the substrate evenly with a Mapei n. 3 notched trowel (coverage: approx. 700 to 1000 g/m2) or with a Mapei n. 4 notched trowel (coverage: approx. 900 to 1200 g/m2), depending on the kind of wood or the type of substrate.
The open time of Adesilex PA is about 5 to 10 minutes. Spread about 1 m2 of the adhesive and set the wood immediately, pressing lightly. Make sure the adhesive transfers completely to the back. The room temperature should be at least +10°C÷+5°C (comply with national industry regulations).
Installing the parquet:
The parquet must be kept in a dry, sheltered place, must not be subject to condensation, and must not be stored directly on the ground.
Before installing, check that the moisture content of the wood is as recommended by the manufacturer and compatible with the ambient humidity.
Press the parquet firmly into place to make sure the Adesilex PA transfers completely. Never install the parquet in contact with the perimetral walls. Leave an expansion joint of about 1 cm around the perimeter, around columns and any elements crossing the floor. Do not bond the parquet pieces to each other (follow the flooring manufacturer’s instructions).
Sanding the parquet:
Before sanding, make sure the wood is stable and that the adhesive is completely dry (wait at least 2 to 3 days). At low temperatures and over substrates that are not very absorbent, drying time could be longer.
Clean tools and machinery with alcohol.
Consumption varies according to the type of substrate from 600 to 1200 g/m2 with MAPEI trowel n. 3 or n. 4.
Adesilex PA is stable for 24 months when stored in a cool, dry place in its original sealed packaging.
