PREPARATION:

The professionals at Johnstone's understand that preparation is the key to a flawless finish, so take your time now and follow the straightforward instructions below, and you will be rewarded with a stunning new appearance. Make sure all painted surfaces are clean, dry, free of grease, and without any loose or flaking material before you begin.

Preparing wall for paint

 

Remove any rust, mill scale, or loose paint that may be present. Wipe the surface clean after lightly sanding it with a fine waterproof abrasive paper. When dry sanding, always take care not to breathe in any sanding dust and always wear a face mask.

APPLICATION:

Now that you are prepared to start painting, give the paint a good swirl. There is no need for thinners because Johnstone's paints are produced to the highest standards and are ready to use right out of the tin. Make sure there is plenty of airflow while drying and applying.

Stir the paint before applying

 

Wear an appropriate cartridge respirator or air-fed respiratory protection equipment when brushing big interior surfaces or in small places.

Use only a brush to apply. Apply freely, but avoid spreading too much. Normally, one coat is adequate, but if more coverage is needed, a second can be applied after it has dried overnight.

 

Painting over damp wall

 

If a gloss finish is required, wallpaper and emulsion paints may be applied immediately; otherwise, seal with Johnstone's Quick Dry Primer Undercoat or a premium matt emulsion.

CLEANING:

Immediately after doing all of your painting, make sure to wipe your brush with White Spirit or Turpentine Substitute and remove as much paint from it as you can.
