How do I apply stain to a privacy fence with tight board spacing in my Riverview NB backyard without making a mess?

Tight-spaced fence boards are one of the trickier staining jobs for a DIYer, but with the right tools and technique you can get clean, even coverage without staining your lawn, your neighbour's fence, or yourself.

The core challenge with a privacy fence — especially the tongue-and-groove or tight-board styles common in Riverview backyards — is that a roller or wide brush pushes stain into the gaps and it drips straight through to the other side. The solution is to work methodically, use the right applicator for the spacing, and protect everything below the fence before you start.

Choosing the Right Applicator

For tight-board privacy fences, a pad applicator (sometimes called a stain pad or fence applicator) is your best friend. These flat foam pads on a handle glide along the face of the boards and deposit stain evenly without forcing it into gaps. They're available at most hardware stores in Moncton and Fredericton for around $10-15. A 4-inch brush works well for getting into any gaps that do exist and for cutting in at the top and bottom rails. Avoid pump sprayers on tight fences unless you have full containment on the back side — overspray and blowthrough will stain your lawn, garden beds, and anything behind the fence.

If you do want to use a sprayer for speed, use a back-roller technique: one person sprays, a second person immediately follows with a brush or pad on the back side to catch drips and work the stain in. This is how professional crews handle large fence jobs efficiently.

Prep and Protection

Lay a canvas drop cloth or plastic sheeting along the base of the fence on both sides before you open the can. Stain drips are inevitable, and on grass they're not the end of the world — but on a concrete patio, interlocking brick, or your neighbour's lawn, they're a headache. Tape off any metal post caps or hardware with painter's tape.

NB-Specific Timing

In Riverview, aim to stain your fence in late May through early September, ideally on a dry day with temperatures between 15°C and 28°C. Avoid staining in direct afternoon sun — the fence boards heat up and the stain dries too fast, leaving lap marks and uneven absorption. Early morning, once the dew has burned off (usually by 9-10am), is ideal. New Brunswick's summer humidity can slow drying significantly, so check the forecast and avoid staining if rain is expected within 24-48 hours.

If the fence is new pressure-treated lumber, wait at least 60-90 days before staining. New PT wood is saturated with preservative and moisture — stain won't penetrate properly until the wood has dried and weathered slightly. Test it by sprinkling a few drops of water on the surface; if the water beads, it's not ready.

Application Technique

Work top to bottom, one or two boards at a time, keeping a wet edge. Apply stain with the pad or brush in long, even strokes following the wood grain. Don't overload your applicator — thin, even coats penetrate better than heavy ones that sit on the surface and peel. For a semi-transparent stain (the most popular choice for cedar and pressure-treated fences in NB), one coat is often sufficient on raw wood. A second coat can be applied after the first has dried if you want deeper colour, but check the manufacturer's instructions — some stains specify a maximum of one coat.

When to Hire a Pro

If your fence runs more than 30-40 linear feet, or if it's a double-sided privacy fence where both faces need staining, the job grows quickly. A professional with a proper airless sprayer and back-roller setup can stain a full backyard fence in a fraction of the time. Expect to pay $5-12 per linear foot for professional fence staining in the Riverview/Moncton area, depending on fence height and condition. If your fence needs cleaning, sanding, or old stain removal first, that adds to the cost and prep time.
