After staining wood do you have to seal it? After staining wood, you have to seal if because the wood remains a porous surface. If you're just using a regular stain, it can provide some degree of protection compared to totally unfinished wood. But it isn't good enough.
Wood is dried-out and dull if you do not apply some sort of sealer. Staining and finishing are two very different things. By applying pigments, a stain is meant to darken or dye wood, but the wood is not preserved by staining.
Most stains should be sealed to prevent bleeding. After smoothing the stained wood, apply a sealer coat of thinned shellac, sanding sealer, or other appropriate sealer. Do not use shellac with NGR or water-base stains. If you plan to finish the piece with polyurethane, make sure the sealer is compatible.
Wait 24 hours before applying sealant. Oil-based wood stains have some advantages over water-based stains. If chemical fumes are not a concern, an oil base may be the right wood stain choice. They dry much more slowly, and slower dry rates allow a more even application.
After staining wood, you will want to finish with a topcoat sealer to protect your wood project. Apply a sealant and let it fully cure before handling!
Let water-based stains dry for two to three hours and oil-based stains for four to six hours before applying a polyurethane sealer. The best way to get a smooth finish is to apply the first coat of sealer, let it dry, and then lightly sand the surface with 220-grit sandpaper before applying a second coat.
Answer: Most people like to stain and seal at the same time, although you can come back a week later and seal if you like. If you're going to wait between staining and sealing, just do a light power wash to clean the concrete and let it dry prior to sealing.
We always recommend two coats of stain for any wood project, but you should only apply as much stain as the wood can absorb. Extremely dense hardwoods may only be able to absorb one coat of wood stain. The general rule of thumb is to apply only as much deck stain as the wood can absorb.
Whenever you stain raw wood, it's important to varnish or seal it before use. Otherwise, the stain could absorb oils and grime from use, and you might ruin that stained surface.
Applying a topcoat sealer is not required, but a finish protects the stained wood from scratches and keeps it from fading over time. If applying a polyurethane wood finish with a brush, apply one to two coats. If using a spray can, hold 8 to 12 inches from the surface and apply two or three light coats.
Although a wood stain is more expensive than a sealer, it can last up to 5 times longer and looks more professional. So you certainly get your money's worth. Here at DeckMaster™, we recommend using wood stains for your deck and fence maintenance.
The primary pro with stain is that it provides protection to the deck surface. This includes for all things, including UV rays, mold, and mildew. However, a sealer is still needed on top of a stain since a sealer alone will not provide a sealed surface. A stain is also available in an array of colors.
Can I stain on top of old stain? Yes! In fact, applying stain over stain is a fairly simple process. It works especially well if you're applying a dark stain over a lighter stain.
No, the sticky stains will not dry after some time, which is why it is important to wipe off the excess wood stain. If you don't, your work will end up sticky because the stain did not dry properly. You will have to use mineral spirits, more stain, or sandpaper to fix the mess.
You should sand after the first coat of water-based stain to flatten any wood grain the water raised, but it's unnecessary after that. You don't need to sand between coats of gel stain or oil-based stain.
Apply a second coat of stain after the first has dried fully. This will usually produce a darker coloring, but it adds a step to the process and slows production. Substitute a glaze or gel stain for the liquid stain. Glazes and gel stains usually contain a higher ratio of pigment.
Stains and oils penetrate wood best when it's cool and dry. If it rains within 48 hours of applying a treatment, the water will soak into the wood, and try and displace the stain. This can cause a blotchy, flaky look, rather than a smooth, even, coat.
If you apply a second, unnecessary coat of stain to wood that is already adequately covered, you risk creating a tacky surface that is prone to early peeling because the second coat is not penetrating the wood surface, but simply laying on top of the first coat of stain.
Applying a second coat of stain to change the color is something you might try once, but the chances of success are not very good. A second coat of stain can cause other issues like peeling of the top coat(s).
Wipe the stain off immediately if you'd like a lighter tone. But for a deeper tone, leave the stain on the wood for 5 to 10 minutes before wiping it off. Be sure to wipe off all the excess stain going in the direction of the grain of the wood.
While staining creates a rich, deep color that highlights natural wood grain, it does not provide long-term protection. Without a protective top coat, wood can be damaged easily due to contact with water, food, or sharp objects. A polyurethane top coat protects the wood from scratches, stains and water damage.
Because the additional coat is not penetrating the wood, it is simply layered on top, which will cause the coat to be more fragile and will not offer the same level of protection as the proper amount of stain. Additionally, moisture in the wood can not escape, which will result in the stain peeling.
Know When it's Time to Seal
Simply pour a bit of water on the wood. If it absorbs quickly, then it's ready to be sealed. However, if the water pools and sits on top of the wood, wait a few more days.
