General
These inert materials provide an excellent surface for painting once clean and dry. The key differences
for surface preparation are; surface porosity, hard/smooth surfaces and weak/powdery surfaces.
Porous surfaces will require a sealer, hard/smooth surfaces will require a special adhesion primer
and weak/powdery surfaces will require a penetrative primer.
Surface preparation
Earthenware, terracotta and unglazed brick
These materials are inert and porous, but offer an excellent surface for painting. The surface simply
needs to be thoroughly clean and dry. Their porous nature may mean that inadvertent stains may
be pulled deep into the surface, which may make removal difficult. This may be a particular problem
when clear finishes are applied.
D802.1 Wash surfaces
Thoroughly wash surface with Resene Paint Prep and Housewash (see Data Sheet D812)
using a nylon bristle brush or broom. Thoroughly scrub the surface to ensure complete
removal of all grease and other contaminants. Rinse thoroughly with clean water and
allow to dry.
D802.2 Remove all moss and mould
Thoroughly clean down to remove all loosely adhered material. Treat areas of moss
or mould infestation with Resene Moss & Mould Killer (see Data Sheet D80) correctly
diluted with clean water. Leave for up to 48 hours to achieve full kill. For heavy
infestations further applications may be needed. Wash thoroughly with clean water to
remove residues.
D802.3 Seal surfaces
Allow to thoroughly dry out then seal with a full coat of Resene Sureseal (see Data Sheet
D42) or Resene Waterborne Smooth Surface Sealer (see Data Sheet D47a).
D802.4 Seal smooth surfaces
Allow to thoroughly dry out then seal with a full coat of Resene Waterborne Smooth Surface Sealer (see Data Sheet D47a).
Glass, glazed brick and vitreous tiles
These materials are similar to that described immediately above except their surfaces are even smoother. Surface preparation requires careful
cleaning followed by a coating with high specific adhesion properties, such as Resene Waterborne Smooth Surface Sealer (see Data Sheet
D47a).
Refer above for the following surface preparation clauses.
D802.1 Wash surfaces
D802.2 Remove all moss and mould
D802.4 Seal smooth surfaces
Earthenware, hard fired
non-absorbent tiles,
terracotta and unglazed
brick
Glass, glazed brick, hard stone, slate, soft stone, synthetic stone
and vitreous tiles
Referred to in Resene specification sheets:
13 Brick and terracotta 14 Clay tiles, decorative aggregate flooring, hard fired non-absorbent tiles, slate and stone

For repaints see D87

D802
Hard fired non-absorbent tiles (quarry tiles), hard stone (including aggregate flooring)
and slate
These materials, although slightly textured, are non-absorbent. Cleaning with detergent or Resene Emulsifiable Solvent Cleaner (see Data Sheet
D804) will prepare the surface satisfactorily for painting. These non-absorbent surfaces will require coating with specific adhesion primers
particularly if the surface is to be stressed, such as a floor.
Refer above for the following surface preparation clauses.
D802.1 Wash surfaces
D802.2 Remove all moss and mould
D802.4 Seal smooth surfaces
Soft stone (Oamaru stone and sand stone)
These materials have generally weak surfaces that are not particularly suitable for overcoating. Deeply penetrative primers may be used to
consolidate the surface, but such treatments may result in spalling of the entire consolidated surface. Strengthening may be accomplished with
Resene Stone Strengthener (see Data Sheet D904), which deposits silica crystals into the matrix of the stone without changing the essential
morphology of it. Cleaning should be as gentle as possible in order not to damage the surface. Steam cleaning following fungicidal washing is the
preferred method. Penetrating siloxane waterproofing treatments are often the best coating option. For further information refer to the Historic
Places Trust Conservation Bulletin No. 3 for the conservation of historic stone structures.
Refer above for the following surface preparation clauses.
D802.1 Wash surfaces
D802.2 Remove all moss and mould
D802.5 Steam clean
Steam clean surfaces to remove weak unbound layers of sand, dirt and grit for a sound paintable surface.
D802.6 Treat with water repellent
Saturate soft stones with Resene Aquapel (see Data Sheet D65).
Synthetic stone
These materials are generally based on cementitious binders or use a polymer matrix such as epoxy or unsaturated polyester. The former should
be prepared as for cementitious substrates (see surface preparation D83) and the polymer based materials prepared as for GRP and GRE (see
surface preparation D803).
