What is the difference between stain and lacquer?

Stain and lacquer serve completely different purposes in wood finishing, and understanding the distinction helps you make better decisions about your project. In simple terms: stain adds colour to the wood, while lacquer provides protection. Most quality wood finishing projects require both.

What Stain Does

Wood stain is a colourant that penetrates into the wood grain to change its appearance. It soaks into the fibres and enhances (or completely changes) the natural colour of the wood. Stain on its own provides little to no protection against wear, moisture, or UV damage.

There are two main categories of wood stain:

• Oil-based stains (such as Minwax Penetrating Stain) soak deeper into the wood, produce richer colour, and allow longer working time. They take 8 to 24 hours to dry between coats. Oil-based stains are our preferred choice for most Edmonton projects because they handle the city's dry climate well and produce consistent results.
• Water-based stains (such as General Finishes water-based stain) dry faster, have lower VOC content, and clean up with water. They raise the wood grain slightly, which requires an extra sanding step between coats. They are an excellent choice when low odour is a priority.

What Lacquer Does

Lacquer is a clear (or tinted) protective topcoat that sits on top of the wood surface. It creates a hard, durable shell that protects against scratches, moisture, heat, and daily wear. Without a topcoat like lacquer, stained wood would quickly become damaged and lose its colour.

Professional-grade lacquers from M.L. Campbell and Sherwin-Williams are what we use at iPaint. These products are sprayed with HVLP equipment to produce a smooth, even finish that brushing or rolling cannot match. Lacquer is available in several sheen levels: matte, satin, semi-gloss, and high gloss.

Lacquer vs. Polyurethane vs. Varnish

Homeowners often confuse these three protective topcoats. Here is the practical difference:

• Lacquer dries the fastest, produces the hardest film, and is best applied by spray. It is the professional standard for railings, trim, and cabinetry.
• Polyurethane (oil or water-based) is more flexible and slightly more forgiving to apply. Varathane and Minwax make popular consumer-grade options. It works well for floors and high-traffic surfaces.
• Varnish offers the best UV resistance and is typically reserved for exterior applications or marine environments.

Why You Need Both

A proper wood finishing system always includes a colourant (stain) followed by a protective topcoat (lacquer, polyurethane, or varnish). Skipping the topcoat leaves your stained wood vulnerable to damage. Skipping the stain means you lose the ability to control the final colour. We apply a minimum of two clear coats over every stain job to ensure years of durability. Contact us for a free consultation on your wood finishing project.
