Follow the current thinning, cleaning and safety instructions.\u003c\/p\u003e\u003ch3\u003eIs it an opaque wood paint?\u003c\/h3\u003e\u003cp\u003eNo. It is a clear or translucent finish intended to leave the wood character visible. Test the chosen finish on the actual timber.\u003c\/p\u003e\u003ch3\u003eCan I use it outside?\u003c\/h3\u003e\u003cp\u003eYes, on suitable exterior wood within the specified preparation and coating system. It is not a maintenance-free treatment.\u003c\/p\u003e\u003ch3\u003eCan I use it on floors?\u003c\/h3\u003e\u003cp\u003eThe manufacturer lists floors under light mechanical and chemical stress. Confirm suitability for the expected traffic and allow the prescribed curing time before normal use.\u003c\/p\u003e\u003ch3\u003eCan it be used below a boat's waterline?\u003c\/h3\u003e\u003cp\u003eThe listed boat application is above the waterline.

Tinted product offers better sunlight protection than untinted product according to the manufacturer.\u003c\/p\u003e\u003ch3\u003eAre the timber scenes actual Unica applications?\u003c\/h3\u003e\u003cp\u003eNo. The dining-table and exterior-seating scenes are AI-generated illustrative inspiration, not exact tinted shades, verified Unica Super 20 applications or protection demonstrations.\u003c\/p\u003e\u003ch2\u003eTechnical and safety guidance\u003c\/h2\u003e\u003cp\u003eRead current technical and safety information before use. \u003ca href=\"https:\/\/www.tikkurila.co.uk\/unica-super-20\" target=\"_blank\" rel=\"noopener\"\u003eView Tikkurila Unica Super 20 guidance\u003c\/a\u003e.
