Glossary
Absorbency refers to the degree to which a surface or marital takes in liquids.
Materials with high Absorbency such as matte painted walls, plaster and untreated wood (especially softwoods) take in liquids easily. As a result, this can make them prone to staining, mould and frost damage. Materials that aren’t absorbent like plastics, treated wood, glossy paint and tiles do not take in liquids easily, if at all. This makes them more resistant to staining, mould and frost damage.
Materials such as: sealant, paints, grout and cement/concrete transition from high Absorbency to low Absorbency when they have dried or cured.
So when using these materials it’s important to be conscious of what moisture or liquids get absorbed as this can affect the drying/ curing time and its finish. Along with the same principle, surfaces can be treated to change their Absorbency. Primer is used on a surface to provide a non Absorbent layer before painting and wood Varnish creates a non Absorbent shell protecting the wood.
Acrylic is a term that refers to products that contain compounds derived from acrylic acid (for example Polyacrylonitrille and PMMA) is a glassy thermoplastic that can be used in adhesives, paint, fillers and coatings or can be cast and moulded. Acrylics are a collection of materials that pertain to a wide range of uses in […]
Wood stain is a term that describes anything that colours wood. There are products that solely stain the wood but there are also others such as oils, varnishes and waxes that both stain and teat the wood (make it less absorbent and resistant to damage). Wood stains consist of a pigment or dye (for colour) […]
