For most tongue and groove (T&G) installations, you should nail the boards. However, screws are preferred for high-stress areas like ceilings, mobile applications, or porch boards to prevent boards from vibrating or pulling loose over time.
You always nail through the tongue (often called "blind nailing" or "edge nailing"). Nailing through the groove will prevent the next board from fitting properly and can damage the wood's edge.
Installing tongue and groove (T&G) involves securing the planks to a wall or ceiling joists using a "blind nailing" technique. You start with the first board level, nail it through the tongue at a 45-degree angle, and lock the next board’s groove over it. This hides the fasteners completely.
I find the 15 and 16 to split the tongue pretty easily with one shot. If your 15 gauge is splitting tongues, rotate it 90⁰, it has to do with how the point is going into the wood grain. Depends on the material, I typically use 18g and a few dabs of adhesive.
Tongue-Tite is a specialist screw designed for softwood, hardwood and fibre tongue & groove floorboards. With the Tri-Lock™ TS threadform the screw will drive straight through the boards & into the substrate without pre-drilling.
Tongue and groove is traditionally done by face nailing the inside edge of the starter row, leaving the tongue exposed, and angle nailing through the tongue. Each subsequent row is tightly placed groove-to tongue on that edge, and angle nailed through the tongue.
For fasteners, we recommend using a 2-5/8” exterior ring shank nail or coated deck screw.
Use 𝟏𝟏𝟐 to 2-inch, 15-gauge or 16-gauge finish nails. For most ceilings or walls, blind-nailing through the tongue at a 45-degree angle ensures the fasteners remain completely hidden.
Whether 16-gauge is "better" depends entirely on your project. In the gauge system, lower numbers mean thicker metal. Therefore, 16-gauge is thicker, stronger, and heavier than 18-gauge.
Tongue and groove (T&G) pine is best nailed at a 45-degree angle through the base of the tongue (known as blind nailing) into every stud or joist, which conceals the fastener. For the first board, or when necessary for security, you may face-nail (straight in) near the edge, which will be hidden by baseboard or trim.
Start at one bottom corner of your wall and make sure that your first board is level by using a hand level or a laser level. The tongue of the board should be facing up towards the ceiling while the groove faces down towards the floor.
Drywall Cost. You might be surprised to learn that wood tongue and groove panels are about three times more expensive up front. That price only accounts for the material.
For a tongue and groove (T&G) ceiling, the best fasteners are 15- or 16-gauge finish nails or 1/4-inch crown staples, measuring 𝟏𝟏𝟐 to 2 inches long. Always use the blind nailing technique, shooting the nails at a 45-degree angle through the tongue of the board so the holes are completely hidden by the next piece.
Common scalloped tongue causes include:
In addition, tongue and groove wood can be used for both decorative and functional purposes, depending on the type of wood and the finish applied. However, there are also some disadvantages to using tongue and groove wood. One disadvantage is that it can be more expensive than other materials, such as drywall.
Normally when you install wood paneling, you're required to make sure that each of your boards are joined on a stud. This ensures that both ends of the board are secured down, because unsecured ends can warp away from the wall after some time.
16-gauge nails are the most versatile size, so a 16-gauge nail gun is a great option if you need it for many different projects. 15-gauge nails are most often used for installing thick trim. 18-gauge and higher-gauge nail guns are best used for fine detail work, furniture repair and thin trim work.
Both 14 gauge and 16 gauge stainless steel resist rust and stains. The thickness does not change how well they fight corrosion. You get the same protection from both if you clean them right.
The standard thickness for most American metal sinks is 18 gauge. It's durable and easily supports garbage disposals. It's also quieter than thinner sinks, which you'll appreciate when dropping other metal things into it.
You always nail through the tongue (often called "blind nailing" or "edge nailing"). Nailing through the groove will prevent the next board from fitting properly and can damage the wood's edge.
The general rule says you should have a square tongue that's roughly one-third of the stock thickness and centered on the edge. Working with 3⁄4″ stock, that plays out to a 1⁄4″-thick by 1⁄4″-long tongue, and a matching groove. A longer tongue (one that's 1⁄2″ long for example) is prone to break at the shoulder.
The higher the number, the thicker the screw. So yes, a #10 screw is thicker (and usually stronger) than a #8 screw.
Nails are a favorite for large jobs in construction because they're cheaper than screws and offer shear strength — or the ability to withstand shear pressure, where two surfaces slide past each other.
To nail tongue and groove (T&G) planks, use the blind nailing technique. Angle a 15, 16, or 18-gauge brad nailer downward at approximately 45∘45 raised to the composed with power45∘ and fire directly through the base of the exposed tongue. This secures the board while allowing the groove of the next plank to hide the nail heads.
