Taping a blank canvas is one thing, but what if you need to mask areas on an already-painted canvas? Stephen is back with more expert tips to help you achieve clean lines and shapes when working with both oil and acrylic paints.

Masking a Painted Canvas: Tips and Tricks

In our previous blog post, we covered how to tape a blank canvas to prevent paint from bleeding. It’s a simple but powerful technique that can dramatically improve your painting’s final look. Now, we’re tackling the same concept, but with a twist—how to tape and mask a canvas that’s already been painted.

Stephen demonstrates how to create clean, sharp lines on a pre-painted canvas, whether you’re working with oil or acrylic paints. He even shows you how to use tape to create shapes and add different effects to your artwork. This is especially useful for acrylics, where you can thin the paint with varnish or resin for unique finishes.

What NOT to do 

However, there’s a catch! If you don’t let your paint dry—or as Dad likes to say, “cure”—properly, you could end up with a mess instead of a masterpiece. This tutorial isn’t just about what to do, but also what to avoid. Dad shares some common pitfalls and mistakes that can lead to disaster, so you know exactly what to watch out for.
