PA-68   

PProduct Description :

Parquet Adhesive PA 68 is a one-part, moisture-curing, rigid/flexible polyurethane adhesive free from solvents,water, alcohol, and amine. Easily applied by trowel. Good filling properties, no-shrinkage and easy to apply using a dented spatula. Excellent resistance to water, temperatures and ageing. Characterised by a high shear resistance (DIN 281) and an exceptional resistance to the permeation of humidity, it guarantees the safe laying of wood floors on screeds with a high humidity level content.Parquet Adhersive is the first one-part adhesive for parquet flooring which is recognized by the architectural magazine ”NUOVO VERDE AUREO Architettura, Manuale Tecnico-Pratico della Casa Sana e dei Prodotti Ecologicamente Migliorativi” as a highly innovative solution both from the high product technical-performance as well as the ecological characteristics.

 

Applications :

Designed for structural bonding of wood elements on porous and non porous supports, Parquet Adhesive PA 68 isspecific for the bonding of any type of wood flooring (including beech-wood, maple and exotic woods),lamparquet, small slats, maxilstone, prefinished and laminate on all types of untreated or consolidated cement screeds and on existing flooring. Its high green strength keeps the elements to be bonded in place; therefore, it is ideal for large surfaces of wood (Parquet) flooring. Particularly suitable for heated floors and for the bonding of wooden floors on existing ceramic, marble, palladian, wood and natural stone floors.

 

Main Advantages:

Easy bonding between different materials

Compensation of the movements caused by thermal dilatation, vibration and shrinkage without the risk of breakage

One-part Clean and simple to use

Solvent-free, completely odourless

No product waste during and after use

High humidity resistance up to 3%

Application without harmful exhalations. Determination of VOC for Control of Emissions from Products for Flooring Installation1. Protocol n° 24271/1, 31/01/2002, CATAS S.p.A.

2. Protocol nr. 943 dated 10/09/99, Environmental Hygiene and Industrial Toxicology Laboratory,Pavia – Italy)

High shear strength (DIN 281).

Instructions

The support must be compact, seasoned, clean (free from oil residues and old adhesives) and dry at the moment of application. If the foundation humidity is more than 3% in weight, then a special pre-treatment of the floor basement is necessary. Apply the product in a uniform manner using a dented spatula and place the covering on the freshly applied adhesive.

PARQUET LAYING MUST BE EFFECTED WITHIN 1 HOUR FROM ADHESIVE APPLICATION

 

Application Advice :

Do not dilute product

Use latex gloves or protective hand-cream for quick cleaning

Remove immediately eventual product traces on the parquet before its hardening.

Avoid the leakage of material from the sides of the staves due to the risk of whitening effects resulting from the contact of the adhesive with solvent based polyurethane paints if used in particular humidity condition on specific types of wood like the exotic ones. No risk with water-based paints.
