MURALE

Universal adhesive for wall coverings, ready to use

Uses

QUELYD MURALE is a ready-to-use adhesive suitable for hanging:

  • textured string wallcoverings/stringcloth on a paper- or non-woven fabric backing
  • needlepunch with paper backing
  • paper-backed or coated textile wall coverings
  • paintable fibreglass
  • flocked or velvet wallcoverings on a paper- or non-woven fabric backing
  • PVC wall coverings on a paper with woven or mineral backing
  • thin expanded polystyrene in rolls (2 to 5 mm thick).


IMPORTANT: The backing of some wallcoverings (e.g. textured string wallcoverings) must be carefully moistened prior to hanging. An appropriate soaking time must be observed. Follow the manufacturer's recommendations.

Application

PREPARATION
For use onto gypsum-based substrates, gypsum wallboards, prepared old wallboards, painted walls, plaster coatings, particleboards and wooden substrates.
Preparation should be in accordance with building standards. Walls must be sound, even, smooth, permanently dry and free from dust, grease or other contaminants, and have normal porosity.
The moisture content for plaster based substrates should be lower than 5%, for wood and derivatives between 10 and 14%.
 
Absorbent substrates
Fill all cracks and holes. Fix flaky and chalking substrates with QUELYD PRIMA primer.
For gypsum wallboards, particleboards and plywood use QUELYD PRIMA primer.
On waterproof and fireproof wallboards it is compulsory to use solvent-based primer IMPREGLUE.
Do not use rich, nutritive primers or "remaining paint" type mixtures, which may reduce substrate porosity.
 
Painted surfaces
Scrape off any flaking paint and smooth the surface with a sanding block. Glossy and semi-gloss paint should be sanded to bring porosity to the substrate. Eliminate sanding dust. A coat of adhesion promoting primer QUELYD PRIMA should be applied prior to wallcovering installation. Allow to dry for at least 24 hours.
 
Old wallpapers and wallcoverings
Remove old wallpaper and colour wash using Quelyd Dissoucol Wallpaper Remover. Rinse thoroughly to get perfectly clean substrate.
 
PASTING THE WALL
Stir well before application.
Adhesive is READY TO USE. DO NOT DILUTE.
Using a medium pile roller or a notched  trowel N°0, paste the wall generously and regularly over a surface area slightly greater than the strip width (consumption: 150-250 g/m²).
 
HANGING WALLCOVERING
Use a plumb line to make sure the first strip is perfectly straight. Hang the first strip. Gently slide the wallcovering until the outer edge is lined up with the starting line. Hang subsequent strips edge to edge, or overlapping, according to the manufacturer's recommendations and in the predefined order.
 
Using a wallpaper brush or a plastic spatula, carefully press the wallpaper from the top downwards and from the centre toward the edges, taking care to roll out air bubbles and spread out any uneven patches of paste.
 
Flatten the joints according to manufacturer’s instructions. Excess lengths near the ceiling and skirting board will be trimmed using a cutting blade, guided by a broad knife.
 
Immediately remove fresh splashes by eliminating the maximum amount of adhesive with the tip of a knife, then wipe down with a clean damp sponge (do not rub).
 
REMARKS 
- Carefully read the hanging instructions and strictly follow the manufacturer's recommendations
- Do not start hanging wallcoverings from an outside corner
- Not suitable for use with a pasting machine
 
Cleaning
Hands, tools and spillages can be easily cleaned with cold water
