All Amsterdam acrylics are intermixable, and Transparent Yellow Medium behaves predictably in mixes given it is transparent. Start by mixing it with titanium white for tints and with a small amount of its complementary colour to knock back the intensity rather than reaching for black, which tends to deaden a mix. Keep a swatch card of your mixes with the ratios written on it, because you will want to repeat one later.

Transparent Yellow Medium is rated +++ on Royal Talens' scale. Three pluses means the colour is rated to last at least 100 years under museum conditions, two pluses at least 25 years. Museum conditions means indoors and out of direct sunlight. That rating is why work painted in Amsterdam Standard Series is safe to sell, provided the buyer is not hanging it in a north-facing window.

The Amsterdam Standard Series runs in 20ml, 120ml, 250ml, 500ml and 1 litre, though not every colour is made in every size. We carry the sizes that move, and the 500ml jar is the one to choose when you are painting large, teaching, mixing in volume or working on murals and props. If you want a size you cannot see on the site, ask us and we will check what Royal Talens produces in that colour.

Royal Talens, based in Apeldoorn in the Netherlands. The company was founded in 1899 and also makes Rembrandt oils and pastels, Van Gogh oils and watercolours, Cobra water-mixable oils, Ecoline liquid watercolour and Bruynzeel pencils. Amsterdam acrylics are manufactured in the Netherlands, not contract-made offshore, which is part of why batch-to-batch consistency is reliable when you are mixing a colour you need to match again later.

It is optional for durability indoors, since acrylic cures water resistant on its own, but it is worth doing for anything that will be handled, sold, displayed in a public space or ever need cleaning. Varnish gives you a sacrificial layer that takes the dust and can be removed and replaced. Wait until the painting is properly cured, which means days not hours, and longer over thick texture. Choose gloss, satin or matte deliberately, because it changes the look.

Yes, it is a common mural choice, and the alkali resistance is the reason. It adheres to stone, plaster, concrete and render without a specialist masonry primer, provided the wall is clean, sound and slightly porous. For an exterior mural, finish with a UV resistant exterior varnish. The paint's lightfastness rating assumes indoor museum conditions, and an Australian north-facing wall is a very different ask.

Act while it is wet if you possibly can, because soap and cold water lifts wet acrylic easily. Once it has cured it is a plastic film bonded into the fibres and there is no reliable removal. People have some success softening it with isopropyl alcohol or a dedicated paint remover and working at it with a brush, but the fabric usually shows the damage. The real answer is an apron and old clothes.

Very. The 500ml and 1 litre sizes and the medium viscosity are both suited to covering area fast. It takes to MDF, plywood, cardboard, foam that has been sealed first, plaster and most primed surfaces, dries fast enough to recoat the same day, and the metallic and reflex fluorescent colours in the range cover effects that would otherwise need spray.
