GENERAL DISCRIPTION

Bonding liquid provides good bonding properties with excellent sealing properties for interior and exterior surfaces of concrete, brick, plaster, hardboard and fibre cement.

  • Provides good adhesion for Universal Undercoat over absorbent surfaces;

  • Bonding Liquid is designed to penetrate and bind surfaces previously painted with distemper, limewash and cement paints before overcoating with Emulsion paints.


USES

Recommended on interior and exterior masonry or plaster to provide a sound base for subsequent coats of emulsion paint.

  • Sealer for porous surfaces such as gypsum plaster, concrete, cement stone, hardboard, paper-faced boards and various other types of composition boarding;

  • Bonding Liquid for penetrating and binding chalked, but sound PVA or limewash to the original surface for subsequent coats of emulsion paint.


TECHNICAL DATA

All above technical data, coverage/spreading rate of Classiguard depend on condition and porosity of the surface and the manner in which Classiguard is applied and used. For best results, do not exceed a spreading rate of 12 sq. m. per litre.

  • PACKING SIZE  -  1 Litre and 5 Litre.


APPLICATION

  • READY   -  For use with brush. Brush application preferred to ensure adequate penetration;

  • SPRAY  -  For spray application thin with Spraying Enamel Thinner or Mineral Turps;

  • THINNING  -  Not recommended - Bonding Liquid is supplied ready for use;

  • EQUIPMENT CLEANING  -  Mineral Turps.


STANDARD APPLICATION PROCEDURE

NEW SURFACES - GYPSUM, PLASTER, CONCRETE AND HARDBOARD

  • Remove dust, dirt and plaster splashes;

  • Cut out large cracks and imperfections;

  • Fill with a recommended Crack Filler and sand smooth when dry;

  • Apply one coat of Bonding Liquid;

  • Allow to dry before overcoating.


PREVIOUSLY PAINTED SURFACES - INCLUSING LIMEWASH DISTEMPER

  • Chalked surfaces must be thoroughly wirebrushed and washed down;

  • All loose flaking paint must be removed;

  • Apply one coat of Bonding Liquid, allow to dry before overcoating;

  • Surfaces must always be dry before applying Bonding Liquid.


NOTE: Bonding Liquid will not penetrate a multiplicity of coats of powder and it is essential to prepare the surface prior to the application of Bonding Liquid.

PRECAUTIONS

  • Not suitable as a primer for metal surfaces;

  • Not suitable on alkaline surfaces. In these conditions, Classiseal Plaster Primer should be used;

  • When Bonding Liquid is dry, there should be little or no gloss. A glossy surface indicates that Bonding Liquid has been applied too liberally;

  • Conversely, a loose or powdery surface after application of Bonding Liquid indicates that Bonding Liquid has been applied too sparingly and a further application is required;

  • Do not use Lacquer Thinner or Meths for diluting as this will alter or destroy the quality and performance of Bonding Liquid;

  • Clean all equipment and tools with Mineral Turps after use.


IMPORTANT

  • The ambient temperature must be between 4ºC and 40ºC and humidity between 10% and 85%;

  • Do not paint too early as the wall may still be damp - paint only when the walls are dry;

  • Do not paint in too hot weather, rather paint early morning and after lunch, the slower the paint dries, the longer it lasts;

  • Excessive application thickness and/or rapid drying could lead to cracking;

  • Avoid applying under adverse weather conditions as this could result in poor product performance;

  • Excessively friable surfaces should be cleaned down prior to primer application.


SAFETY

Painting is a relatively user-friendly activity if the proper precautions are taken to ensure safety

  • Always keep out of reach of children and animals;

  • Do not take in orally - harmful if swallowed. Seek medical attention and do not induce vomiting;

  • If accidental contact with skin, wash immediately with soap and water or a good quality skin cleaner;

  • If accidental contact with eyes, rinse immediately with plenty of water and seek medical advice;

  • Do not let a freshly painted room be occupied, particularly not by older people, children, or pets;

  • Wear a respirator if the area being painted cannot be adequately ventilated, and work for short periods only;

  • Ventilate the area to be painted, opening all doors and windows and using fans during application and drying;

  • Protect floors with cloth dropcloths, not plastic, which is far more slippery;

  • Do not paint or store paint near any heat source such as a water heater or fireplace, and never smoke while painting;

  • Make sure your ladder is in good shape. Set the legs on an even surface and lock the cross braces. Do not stand on the top of the ladder nor on the utility shelf. If you are having difficulty reaching a spot, get down from the ladder and move it rather than leaning out;

  • Clean up carefully and thoroughly when you are done for the day;

  • If rags have alkyd paint or thinner on them, leave them to dry outside to avoid any chance of spontaneous combustion;

  • Choose an area inaccessible to children and pets, and when they are thoroughly dry, take them to a toxic-waste dump site.


GENERAL

Different surfaces and environmental conditions require specific painting systems to produce the best possible results - It is, therefore, recommended that you contact a representative from Classic Paints for advice on all your painting requirements, whenever possible.
