{"product_id":"matisse-acrylic-medium-mm38-acrylic-thickener","title":"MATISSE ACRYLIC MEDIUM MM38 ACRYLIC THICKENER","description":"Use MM38 acrylic thickener as an alternative to adding gels and other impasto or building mediums to paint which work by imparting their own thicker bulk to a paint mix.\u003cbr\u003e\r\nThis medium chemically thickens the paint. It is a rheology modifier, that is, it changes the flow and viscosity of the paint, without losing any colour. You may notice a reduced sheen in some colours, which can be adjusted with varnish once dry.\u003cbr\u003e\r\nAdd a few drops to acrylic paint and work it into the paint with a pallet knife.\u003cbr\u003e\r\nContinue to work the paint with the pallet knife until you see the paint thicken.\u003cbr\u003e\r\nIf you don't see results straight away keep working the paint it will thicken, patience is the key here.\u003cbr\u003e\r\nUse within 24 hours of mixing in -\u003cbr\u003e\r\n*Use 2-3 % to your paint - any more than 5-7% (depending on the original viscosity) will not continue to thicken the paint but possibly start to thin it down again.","brand":"Gordon Harris - The Art \u0026 Graphic Store","offers":[{"title":"250ML","offer_id":43483416297531,"sku":"MRMM2M38","price":54.2,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0618\/7299\/6411\/files\/MRMM2M38.jpg?v=1778022178","url":"https:\/\/www.gordonharris.co.nz\/products\/matisse-acrylic-medium-mm38-acrylic-thickener","provider":"Gordon Harris - The Art \u0026 Graphic Store","version":"1.0","type":"link"}
