CLASSISEAL MULTI-PURPOSE PRIMER™ can be used on interior and exterior surfaces. Recommended for sealing new alkaline surfaces such as fibre cement and plaster and is outstanding for crete stone and surfaces that are highly absorbent such as gypsum board and rhino board are successfully sealed with CLASSISEAL MULTI-PURPOSE PRIMER™ for subsequent coats of high quality emulsion paints.

All above technical data are based on CLASSISEAL MULTI-PURPOSE PRIMER™ off White. Coverage/spreading rate of colours depend on condition and porosity of the surface and the manner in which CLASSISEAL MULTI-PURPOSE PRIMER™ is applied and used. For best results, do not exceed a spreading rate of 8m² per litre.

• READY   -  Brush application is preferred to obtain maximum penetration;
  

• SPRAY  -   Application is not recommended;
  

• THINNING  -  Not recommended;
  

• EQUIPMENT CLEANING  -  Water.
  

• NEW SURFACES: Remove dust, dirt and plaster splashes;

• Plaster and Cement: Cut out large cracks and imperfections;

• Fibre Cement: Fill with a recommended Crack Filler and sand smooth;

• Gypsum-combination board: Apply when dry only. Apply one coat of CLASSISEAL MULTI-PURPOSE PRIMER™; Depending on condition and porosity of surface, a second coat of CLASSISEAL MULTI-PURPOSE PRIMER™ may be required before overcoating with 2 coats of high quality emulsion paint;

• RE-DECORATION: Remove completely by scraping, wire brushing, hydro blasting to PVA, Emulsion Paint, bare sound surface;

• Lime Wash, Distemper: Stop and fill all large cracks and imperfections with a recommended in poor condition Crack Filler and sand smooth when dry; Apply one coat or two coats of CLASSISEAL MULTI-PURPOSE PRIMER™ depending on the condition and porosity of the surface.

NOTE: CLASSISEAL MULTI-PURPOSE PRIMER™ will not penetrate multiple coats of lime wash, distemper or cement paints - Overcoat with two coats of CLASSISEAL MULTI-PURPOSE PRIMER™.

• The ambient temperature must be between 5ºC and 35ºC 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.

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.
