Used for pointing gypsum plasterboards with an oblique edge, does not crack at joints, filling minor damage to the wall or ceiling surface, for masking heads with a screw in used for fixing plasterboards to the grid, for smoothing plaster surfaces in traditional or concrete, creates a solid and a dust-free surface with high white density. Perfect for all types of paints. 

• Bonds to the majority of masonry substrates.  

• Easy to mix and apply.  

• Dabs are quickly applied and allows adjustment during boarding. 

 • Capable of accommodating nominal background irregularities. 

• Hand use. 

TECHNICAL DEFINITION  

UNIVERSAL BONDING COMPOUND is an Gypsum based adhesives for interior fixing of plasterboard with or without insulation. Also allows filling of gaps between boards.  

COMPOSITION AND APPEARANCE  

Plaster-based powder filler, containing calcium carbonate and various additives. The mix obtained is white.  

ACCEPTED SUBSTRATES  

Any type of plasterboard with paper face, with or without insulation (glass wool, rock wool, polystyrene).  

• Concrete.  

• Cement filler.  

• Render.  

• Cellular concrete.  

• Clay brick. 

TECHNICAL CHARACTERISTICS  

• Setting time: 2 hours.  

• Adherence on concrete: > 1 MPa.  

• Adherence on polystyrene: breakage of polystyrene.  

• A1 class reaction to fire. 

PRECAUTIONS FOR USE  

The temperature during application and drying must be between 5 and 30° C. Do not apply to damp substrates. Do not use mix that has begun to set. Do not apply to old paint.  

PREPARATION OF SURFACES  

Wall surfaces must be sound, free of dust, oil, and should not sweat damp. In summer, if the substrates are too dry, dampen them slightly. Differences in flatness of up to 15 mm are  

acceptable.  

Old substrates covered by mortar/plaster must be checked for soundness and washed down.  

MIXING FACTOR  

From 13 to 14 l of water per 25 kg sack. Mixing is preferably mechanical.  

APPLICATION Generally, apply in dabs of approximately 10 cm at horizontal intervals of 30 cm and vertical intervals of 40 cm. For insulation containing fibre (glass wool, rock wool), apply an initial coat of gypsum based adhesives.  

ISOCOL MORTAR is then applied in dabs to this line of filler. The surface glued up after applica – tion of the panel should correspond to around 15 % of the overall panel surface. APPLICATION THICKNESS From 5 to 15 mm, depending on flatness of substrate.  

CONSUMPTION From 1.5 to 3 kg/m 2 depending on number and thickness of dabs.  

DRYING TIME UNIVERSAL BONDING COMPOUND is hard in 2 to 3 hours. Complete drying requires 24 hours.
