How to Stretch Watercolor Paper with Masking Tape
Learn how to stretch watercolor paper with masking tape like a pro! Discover essential tips and tricks to achieve the perfect canvas for your next watercolor masterpiece.
One of the key steps to ensuring a successful watercolor painting experience is properly stretching your watercolor paper. In this article, we’ll walk you through the process of stretching watercolor paper with masking tape, ensuring that you create a smooth and wrinkle-free canvas for your artwork.
Why Stretch Watercolor Paper?
Watercolor paper is known to warp or buckle when exposed to moisture, which can lead to uneven color distribution and a less-than-perfect painting experience. Stretching your watercolor paper helps prevent these issues by tightening the fibers and providing a smooth, flat surface for your paints to adhere to.
Supplies You’ll Need
To stretch watercolor paper with masking tape, you’ll need the following supplies:
- Watercolor paper (preferably 140lb or heavier)
- Masking tape (1.5-2 inches wide)
- Clean water
- A large, flat surface (such as a drawing board, plywood, or plexiglass)
- A clean sponge or large brush
- A towel or absorbent cloth
Step-by-Step Instructions for Stretching Watercolor Paper with Masking Tape
Follow these steps to stretch your watercolor paper like a pro:
Step 1: Soak the Paper Begin by submerging your watercolor paper in a container of clean water for a few minutes, ensuring that it’s completely saturated. If you’re using a brush or sponge, gently wet the paper’s entire surface until fully soaked. For heavyweight paper, soaking time may be longer.
Step 2: Remove Excess Water Carefully lift the paper from the water and place it on a clean, absorbent surface. Gently remove any excess water using a towel or cloth, being careful not to damage the paper.
Step 3: Apply Masking Tape Lay the damp paper on your flat surface, ensuring that it’s completely smooth and wrinkle-free. Apply masking tape around the edges of the paper, leaving a small border (about 1/4 inch) between the tape and the paper’s edge. Press the tape firmly onto the surface to create a strong bond.
Step 4: Allow the Paper to Dry Allow your watercolor paper to air-dry completely. This may take several hours or even overnight, depending on the humidity in your environment. As the paper dries, it will shrink and tighten against the masking tape, leaving you with a smooth, stretched canvas.

Tips for Success
- Use high-quality, acid-free masking tape to prevent damage to your paper.
- Choose a heavyweight watercolor paper (at least 140lb) for best results.
- Ensure your working surface is clean and free of debris before starting.
- Be patient and allow the paper to dry completely before starting your painting.
