Opaque stain combines color and protection. Discover when opaque stain is the best choice.

What you need for this tutorial;
Do you want to protect your outdoor wooden surfaces from the elements while simultaneously creating a beautiful look? Opaque stain is an excellent choice. It provides a rich color while the wood grain remains visible.
In this article, you will read everything about opaque stain, how to apply it correctly, and why Osmo Country House Paint is the best choice for a long-lasting, low-maintenance finish.
Preparation before applying opaque stain
Proper preparation ensures good adhesion and long-lasting protection of the wood.
1. Sanding
Does the wood have a previous finish (such as paint)? Use grit 40/80/120 to remove the layer and smooth the surface.
Is the wood oiled? Create a test area to check if sanding is necessary.
2. Untreated wood
Is the wood untreated? Allow the wood to acclimatize for 4-6 weeks first. After that, the wood can be degreased and treated with the opaque exterior stain.
3. Cleaning greyed or dirty wood
Use Osmo Power-Gel Wood Degreaser to refresh greyed or weathered wood.
Ensure the wood is completely grease-free and dust-free before applying the opaque stain.
👉 Tip: Order a sample and test beforehand whether the color and finish meet your expectations.
