Product Description

By entering your model number, you can make sure that this fits.
Due to a shortage of metal cans, the product may be delivered in a plastic gallon jug rather than a metal container.
The UV absorbers in Exterior 450 Topcoat help to stabilize and protect the finish's integrity, but they won't stop the wood from changing color when exposed to sunlight.
Mold and mildew growth are slowed by the inclusion of mildewcides in this topcoat.
Brush, spray, or roll the water-based formula; clean up with soap and water.

Questions & Answers

Is it possible to protect yourself from UV rays with this product?

Yes. Rain exposure, on the other hand, will cause it to fade, so apply several coats (4 or 5). You may need to sand/refinish your outdoor finish once a year, but this is likely to be the case with all outdoor finishes.

Is it normal that when I open my can, the contents are white and thick like yogurt?

Yep! Simply ensure that it is thoroughly mixed. 10 times clockwise, 10 times counterclockwise, then repeat 10 times is my rule of thumb. It will loosen up a little but stay white, and no white should show up when you apply it (if you apply it smoothly and thinly).

Is it okay to use the exterior inside?

Without a doubt. This product has a low volatile organic compound (VOC) content and is virtually odorless. Water is used to clean up the mess. Very long lasting; (hot/cold) temperature resistance On table tops, chairs, and cabinetry, I've used exterior for 50.

Is this a varnished product? I'd like to use a water-based sealer rather than a poly or varnish that will peel over time. ?

It's a polyacrylic water-based product that I used to make Adirondack chairs. If you have A/C or a low humidity environment, it dries quickly. It's not as sticky as some polyurethanes and sands easily. UV protection is included. I applied three coats and sanded lightly with 320 grit sandpaper between each one. After a rain, it clings to the surface nicely. It looks fantastic after four weeks outside.

It's simple to apply, but it doesn't last very long on doors that are exposed to direct sunlight
3/5

It's simple to apply, but it doesn't last long on doors that are exposed to direct sunlight and water. It must be devoid of UV inhibitors or water resistant rather than waterproof. Last summer, I used this to make 16 exterior church doors. The sun- and rain-exposed doors have not lasted a year. I prepared and applied with great care. Four coats of paint were applied to all of the doors. I'm coming for the marine spar varnish. Because it dries quickly, I wouldn't use it on days when the temperature is over 90 degrees or the humidity is high.

My door was saved by a combination of General Finishes gel stain and Exterior 450 water base TopCoat
5/5

I recently used General Finishes Gel stain in brown mahogany and this General Finishes exterior 450 water based top coat to stain my 30-year-old front door. Satin finish, which has a light gloss and shine, as well as smoothness, but isn't overly glossy on my door. It's a odorless top coat that's thin. Allow the gel stain coats to dry for 24 hours after applying them. I applied three thin coats of this water-based top coat after 48 hours. My door dried quickly, so I had to work quickly, using a three-inch foam brush to paint small sections. Because it's self-leveling, don't overwork the top coat to avoid a sloppy result. Cleanup is simple with water. My front door has a fantastic look to it.

The Best Wood Refinishing Product on the Market
5/5

I've experimented with a variety of different wood refinishing brands. br>This is my second project using General Finishes products, and I'm blown away by the finish quality and longevity. br>A year ago, I refinished a dining room table, and it still looks brand new. br>My most recent project was a Teak Bar in our backyard, which was refinshed about 6 months ago and still looks as good as the day we applied the product. br>Follow the directions and be amazed at the quality of the finish. br>This is without a doubt the best product available.

Very let down
3/5

This product reminded me of a craft project component from the 1990s in terms of texture and appearance. ModgePodge is a term used to describe a group of people who It appeared to be diluted Elmer's glue and applied in the same way. Rather than enhancing the stained workpiece, it created a murky blobby effect; however, the topcoat generally enhances the stained piece's appearance. It was a huge disappointment in this case, and it rendered the entire (lengthy) project pointless. I'm tired of Covid's distance and the inability to shop in person, ask experts questions, and compare available products. Please allow me to save you from making a blunder. This item does not have a good "finish. ".

Safeguarding! This is the second time I've purchased 450 flat finish
5/5

This product is fantastic!! br>I have a piece of wood that has been sitting on my deck rail for the past few months as a test. br>The piece of wood is exactly the same as it was when I placed it on the deck rail! Moisture, snow, rain, and bird poop are all examples of this. Even after all these years, the piece of wood is still beautiful! br>To protect my newly constructed Adirondack chairs, I applied three coats. I'm confident they'll stay safe during our spring and summer months. I'm sure they'd be fine if I just left them outside in the snow! br>This is an excellent product that will not alter the appearance, color, or clarity of your woodwork.

It has a lovely finish
5/5

This stuff is pricey, but it's well worth it. It's being used to seal a patio ceiling made of cypress tongue and groove. It applies smoothly, dries quickly, and is water-based, making cleanup a breeze. I can't speak to the durability of my project because it won't be exposed to direct sunlight or the elements. Their coverage of 600 square feet appears to be adequate. With a brush application, I get around 350. On the interior, one coat is applied, and on the exposed areas, two coats are applied. I'm going with FLAT and a natural finish on the boards.

It lasts for a year and a half
5/5

I would highly recommend this product. On the basis of reviews, I made some outdoor furniture. It lasted through the winter, spring, and summer, and now that it's fall, I'll add a few more coats to the furniture. This product has exceeded my expectations, and I will continue to use it.

The best available - This replaces other exterior poly-urethanes, according to the sea salt and the passage of time
5/5

I've discovered a few spar varnishes. Oil-based polyurethane finishes (the names sold in home centers) cracked at my house for 15 years (it's a block from the Atlantic Ocean and its salt air). I used this 450 product on my pine porch ceilings and mahogany railings 5 years ago. It was a breeze to apply (it dries in under an hour, so I was able to get in three applications). In a single day, I was able to put on four coats. It's probably nearly twice as expensive as some brands, but it's well worth it when I don't have to recoat every six months. By the following season, there will be no cracks in the finish. The wood is stunning. If you recoat the wood every two years, it will last a very long time - Railings and ceilings do not need to be replaced every ten years. It moves with the wood much better than oil poly, as do most latex/water-based coating products. As stated on the label, it will take more coats than a traditional polyurethane to achieve the level of protection that is required. If you agree that painting isn't fun, nor is cleaning up turpentine paint or finishing a mess, you'll appreciate the soap-free option. I don't work for the company, so I can't comment on the water cleanup. br>br>No, I don't work for the company - I've recently discovered that Mother Nature tells it like it is when it comes to what works outside - Many other well-known brands' television commercials simply do not stand up to the test of time when exposed to water. It's a fantastic product and the most effective way to deal with outdoor wood.
