كيفية تطبيق طلاء اليوريثان المائي على الأرضيات الخشبية

Water-based urethane finishes for hardwood floors are popular for good reason. They look natural, dry faster, level well, foam less, clean up with water instead of solvents, and don’t always require abrasion between coats. Their low levels of volatile organic compounds (VOCs) also make them safer to use than solvent-based finishes.

Many water-based finishes are dry enough to recoat in 2 to 4 hours, so you can often apply two coats in a day. But because they dry fast, you’ll need to work quickly when the weather is warm and the humidity is low. It’s a good idea to have some experience finishing hardwood floors before trying your hand at water-based finishes.

Water-based finishes generally take about a week to fully cure, much less than oil-based urethanes. Check your finish’s product data sheet for its exact recoat and cure times.

Before you begin to work, get your tools ready. You’ll need a sander or a rotary buffer for sanding and screening. It’s also a good idea to have a shop vac on hand for keeping your work area clean.

Indirect air circulation is important for water-based finishes. However, you don’t want air blowing directly across the wet finish because it could make it dry too quickly. If that happens, it won’t level out evenly and you could end up with application marks. Higher humidity can actually work in your favor because it gives you more working time with water-based finishes.

Testing for dryness is important if you want a successful finish. If the wood isn’t dry enough, the urethane finish won’t bond properly. The same is true for each coat of sealer or finish. If a coat isn’t sufficiently dry before you apply the next one, you could have bonding problems.

أوريون فاغنر^® 930, 940, and 950 dual-depth pinless wood moisture meters read at ¼ inch or ¾ inch deep, and they include quick, easy on-site calibration with the On-Demand Calibrator. If you finish floors for a living, they’re a great choice.

كيفية التقديم

Get your tools ready and clean and prep your floor. During application and until the finish is dry, keep the room above 65°F. Follow the finish manufacturer’s recommendations for application, and contact them if you have any questions about the product.

الخطوة الأولى

استخدم مقياس الرطوبة بدون دبابيس للتأكد من أن الأرضية الخشبية في أفضل حالاتها محتوى الرطوبة المتوازن (EMC) before beginning, and note the reading. Use the brush attachment on your shop vac to clean dirt and dust from the work area. Finish by wiping down the floor with a soft, clean, lint-free rag.

الخطوة الثانية

Apply one coat of water-based sealer and allow it to dry. Since some stains are considered sealers, follow the manufacturer’s recommendations for application. Note that oil-based stains take longer to dry. Allow at least overnight, and even longer for heavily pigmented colors.

Before continuing, set your pinless moisture meter to its ¼-inch (shallow) setting and test to make sure the floor is dry.

Check whether your finish manufacturer recommends abrading the sealer before the next coat; many water-based sealers don’t require it.

الخطوة الثالثة

When the moisture meter shows the floor is dry (close to the reading you took before you applied the sealer), apply the first coat of finish and allow it to dry.

In a three-coat water-based finish system (seal, finish, finish), you apply the sealer, let it dry for about two hours, and then apply the first coat of finish. After that’s dry (use your meter to make sure, preferably on the shallow setting if you have a dual-depth pinless meter from Wagner Meters), you apply the second coat.

Then use your moisture meter again to make sure the second coat is dry. When it is, the floor is ready for light foot traffic.

The general rule is to give the final coat of water-based finish 24 hours to dry before moving furniture back. However, we recommend waiting until it has fully cured, about a week for most water-based finishes, before putting rugs on it and placing heavy furniture. Rugs and furniture can slow the finish’s curing, which can lead to discoloration or a weaker finish.

الأرضية النهائية

Congratulations! You now have a beautiful new wood floor that’s both durable and eco-friendly. If you’ve used your pinless moisture meter at each stage of the process, you’ve given your finish the best chance to look great and perform well for years to come.
