MONT MARTE Masking Fluid Premium 120ml (4.06 US fl.oz), Masking Fluid for Watercolour Painting, Keeps Areas Free of Colour And Edges Crisp, Resists Watercolour, Ink and Pouring Paint

I have always used Windsor and Newton brand but it was unavailable so I tried this. It works just as well as the other and only takes a few seconds longer to dry than the other brand on the same paper. The one problem I have found is that the plastic bottle leaks around the lid after a few uses

Does the trick as described

Good

An absolute must have for anyone using water colours, perfect for keeping tiny and/or sharp details ocluded from your paint, as always test a small piece of scrap paper first as some paper may tear, it dries incredibly fast, so plan your sketch out first, great quality.

Arrived on time and does what it says on label 😎

Useful stuff. Does what it says.

Works well hasn't ripped my paper yet when removed

Great masking fluid. Covers really well and really easy to remove
