What is latex paint?
Latex paint is water-based wall and trim paint, in which pigment and an acrylic or vinyl binder are carried in water rather than a solvent. The name is historical and misleading — modern latex paint contains no rubber latex at all, and the best interior lines are 100% acrylic.
Water-based, and named misleadingly
The defining feature is the carrier. As the water evaporates, the binder particles fuse into a continuous film, which is why latex cleans up with water while it is wet and becomes water-resistant once cured. That easy cleanup, low odour and lower VOC content are why latex has replaced oil for almost all interior wall work.
Quality within latex tracks the binder. A 100% acrylic paint bonds better, flexes without cracking and resists fading better than a cheaper vinyl-acrylic blend — it is the difference that shows up as one coat covering where two were needed, and as a finish that still looks right in five years.
Latex is not the right answer everywhere. It stays slightly softer than an enamel, so on cabinets, trim and doors a harder waterborne alkyd or oil enamel wears better. And a latex topcoat will not grip a glossy oil surface without a bonding primer between them — the two failure modes worth knowing before you switch a room from oil to latex.
How we sourced this
This answer is composed from our knowledge base, which holds only what a regulator, a standards body or a manufacturer supports. The sources behind it are listed below with the date we accessed each one. If a claim on this page has no source under it, that is a bug — tell us and we will fix it.
Where a figure is product-specific — coverage, dry time, recoat time, temperature limits — we point you at the manufacturer's technical data sheet rather than printing a general number as though it were a specification. That distinction is the most common error in this trade, and it is the one that costs people a repaint.
Common mistakes
- Expecting rubber — modern latex paint contains none, despite the name.
- Buying a cheap vinyl-acrylic blend for a job where 100% acrylic would cover in one coat.
- Rolling latex over glossy oil paint without a bonding primer between them.
- Using latex on cabinets and trim, where it stays too soft to wear well.
