Because bathroom walls are exposed to a wide range of contaminants (soap, oil, dirt, grime etc.), meticulous surface preparation is essential. Note that these recommendations exclude bathrooms and showers walls.
Follow these steps:

Surface preparation:
Clean the surface using a cleaner with active oxygen Polyprep 771-135 (liquid) or 771-136 (powder). Then rinse clear with water.
Using a circular movement, rub down the surface with 120 to 150 grit sandpaper. This takes off the surface sheen and allows the paint to adhere to the surface much more easily.
Apply a coat of the primer GoPrime All-in-One alkyd emulsion (150-135).

Ceramic Surface Furnishing

There are many choices available: Sico Kitchen & Bathroon (163 series), Furniture & Cabinets (125 series), Doors & Trim (165 series) or Sico Evolution’s pearl and semi-gloss finishes.

Wallboard
The surface must be clean and dry and nails properly set and filled. Sand the joints to remove any seeding and rough spots, and then dust. Sico manufactures paints that do not require a primer. It is the case for Sico Cashmere, Chamois and Evolution (all finishes except for the Flat for ceilings).

Concrete And Other Masonry

Concrete And Masonry

Concrete And Other Masonry

Concrete must cure for at least 28 days and be thoroughly dry. Remove all spatters, rough patches and burrs by scraping. Eliminate dust with a broom or stiff brush. Use cement mortar to fill in holes, cracks, honeycombing or other obvious defects, and allow curing. If there are efflorescent salts, brush with a diluted solution of Polyprep 771-127 muriatic acid, rinse with clean water and allow to dry. Eliminate all grease, tar and oil stains by washing with Polyprep 875-104 thinner, rinse and allow to dry. Muriatic acid is ineffective in removing oil and other greasy stains. Smooth concrete surfaces like floors and stairs must be treated with diluted muriatic acid, Polyprep 771-127, to obtain better paint adhesion. Allow the acid to work, then rinse thoroughly with clean water.
 

Flaking Paint

Apply a coat of primer and then plug any holes and grooves with putty. If the wood has been treated with a preservative, make sure that all solvent has evaporated.

Painting Melamine

Painting Melamine

For lasting adherence and finish, the preparation of a melamine surface is just as important as the painting job itself. Here are the different steps to follow:
Surface preparation:
Clean the surface using universal cleaner with active oxygen Polyprep 771- 135 (liquid) or 771-136 (powder). Then rinse clear with water.
Using a circular movement, rub down the surface with 100 to 150 grit sandpaper. This takes off the surface sheen and allows the paint to adhere to the surface much more easily. Wipe with a damp cloth to remove any surface dust left over from the sanding.
Apply a coat of one of the following: GoPrime All-in-One alkyd emulsion (150-135) or GoPrime all-in-one latex (190-135).

Before painting, thoroughly clean with the Cleaner, brightener and conditioner for exterior wood Sico 771-333 (liquid) or 771-666 (liquid, environmental choice) or active oxygen cleaner 771-132. As this material is very sensitive to heat, it should be painted with a colour identical to the original siding or a lighter colour. Painting it a darker colour will warp siding permanently.
