Emulsion Paint
Emulsion paint is a common UK term for water-based paint used on interior walls and ceilings. Most modern formulas use an acrylic or vinyl binder and dry to a durable finish.

Paint types used
See the paint types documented in Riley's work, with links to PaintZeal references explaining each medium's properties, uses, and working characteristics.
Acrylic Paint
Acrylic paint is a fast-drying, water-based paint made with pigment and an acrylic polymer binder. It is widely used in art and decorative projects because it is versatile and durable.
Gouache
Gouache paint is an opaque, water-based art medium made with pigment and a water-soluble binder. Traditional formulas dry to a matte finish and can be reactivated with water.
Oil Paint
Oil paint is a slow-drying paint made with pigment and a drying oil binder. It is widely used for artwork because it blends smoothly and develops rich color.
Tempera
Traditional tempera is an artist paint made by combining pigment with an emulsion binder. Egg yolk is the best-known traditional binder, but the broader tempera category can include other emulsion recipes, so a museum record that says only “tempera” does not always identify the exact binder.
Watercolor Paint
Watercolor paint is a water-based art medium made with pigment and a water-soluble binder. It is known for transparent color that settles into absorbent paper.
Surface types used
See the surface types documented in Riley's work, with links to PaintZeal references explaining how each support behaves and is prepared for painting.
Painting Board
Painting board is a rigid artist support made from hardboard, wood, or another stable panel material. It may be sold raw or prepared with a medium-specific ground layer.
Canvas
Canvas is a woven fabric support used for paintings, banners, bags, décor, and other projects. Artist canvas may be raw, sized, acrylic-primed, oil-primed, or factory-coated, and each condition changes how paint absorbs and bonds.
Linen
Linen is a strong woven fabric made from flax fibers and commonly used as a support for fine-art painting. Artist linen may be sold raw or prepared with a ground layer.
Plaster
Plaster is a porous mineral wall and ceiling finish that may be based on gypsum, lime, or other binders. Fresh plaster contains significant moisture and can be highly absorbent until fully dry and appropriately sealed.
Paper
Paper is an absorbent sheet material made primarily from cellulose fibers. Its weight, sizing, surface texture, and wet strength determine how much paint it can accept before buckling, pilling, bleeding, or warping.
Plexiglass
Plexiglass is a rigid acrylic sheet with a smooth, nonporous surface and sensitivity to incompatible solvents that can craze or damage the material.
