Aqua Coat Water Based Clear Wood Grain Filler Gel, 1 Quart

In the 34 years I've been doing woodwork, this is the first time I've used water-based grain filler, and I'm glad to report that this product works great. I have used the oil-based stuff for years to create piano finishes, and while it does an excellent job, it is seriously messy. This stuff reminds me of the old glue paste I used it primary school. It goes on easy, and it washes off with water. There are two things to keep in mind. The first is that you have to understand build coats. Don't expect this stuff to fill in 1 coat. You'll need to apply 3-4 coats, depending on the porosity of the wood, to completely fill the grain. Between coats, use 150 or 180 grit, but only sand it lightly...just enough to give the next coat something to "bite" into. After you get to coat number 3 or 4, let it dry overnight (about 6-8 hours). Come back and sand starting with 120-150 grit to level out the surface. Block sand only! Don't bare hand sand it nor power sand it. Sand until all the shiny spots are gone and the surface is completely flat. Once you get it flat, graduate to 180, then 220, then 320, and then 400 or 600, removing any scratches from the previous coat. Once you get to 400 or 600 and all the scratches from the previous grits are gone, top coat it, and you'll have a mirror finish. The other thing is, DON'T PILE IT ALL ON IN ONE HEAVY COAT. It will crack and ruin all the coats. At that point you'll have the arduous task of removing all of it and starting over. Don't ask me how I know. Lol I hope this helps someone out.

I love this stuff! It's super easy to apply and the results are awesome! Application of Aqua Coat is easy. Wipe it on and rub it into the pores you wish to fill. Wipe off any buildup that remains. Drying time is 30 minutes. Lightly sand your surface; blow, vacuum or brush off any sanding dust and reapply. (Sanding is only to prepare the surface to adhere to the product). Reapply and repeat the process. In three applications pores should be filled and ready for finish, be it lacquer, poly or whatever you choose. Not recommended for oil-wax applications (Rubbio).

I've read the reviews, which are for the most part pretty positive. A few folks had trouble but most did not. My experience with Aqua Clear is generally good. It's not a magical "practically does the job for you" kind of product. It is a grain filler, if you've worked with oak then the need for grain fillers should be somewhat familiar. This product works but it does what it does progressively. It's a water based product so when you apply it the grain in the wood will "rise", that's normal with most woods. After application and a suitable drying time you have to sand it. Some complained that if you use sand paper you sand right through it. That is perfectly okay, the majority of the product is supposed to sand off leaving the product in the "lower" pores and grain. You build the product on the wood through successive layering until you reach the smoothness you are looking for. For very porous woods the directions suggest sealing with an unwaxed shellac first to seal the wood. I can see that as helpful. Sealing wood is not an "effortless" process, no matter what you use. Aqua Clear isn't cheap but it does work if you use it correctly. I use an old PETCO rewards card as an applicator and I give the product ample time to dry. It takes several coats to get the degree of smoothness I like.

The Aqua Coat Water Based Wood Grain Filler Gel has been a game-changer for my woodworking projects. This fast-drying, low-odor clear wood filler is not only effective but also environmentally safe, which is a huge plus for me. I've used other wood fillers in the past, but this one stands out for its non-toxic properties. It's a pint-sized powerhouse that I can always rely on to fill in those pesky gaps and imperfections in my woodwork. Craftsmanship has become a pleasure with this wood filler gel. It seamlessly blends with the wood grain, leaving a flawless finish. The fact that it dries quickly allows me to proceed with sanding and finishing sooner, saving me valuable time on my projects. The low odor is a breath of fresh air compared to other products I've used, making my workspace much more comfortable. In a world where environmental consciousness is vital, I appreciate that Aqua Coat has created a product that not only works exceptionally well but also prioritizes safety for both users and the environment. This wood filler gel has become a staple in my woodworking toolkit, and I can't recommend it enough to fellow wood enthusiasts. It's a must-try for anyone looking to enhance their woodworking experience with a top-notch wood filler.

This product produces a completely clear fill on open pored woods like oak, walnut, ash, hickory, etc. However, it does require a small amount of skill and the right technique to use it (as do all grain fillers), so I'm not surprised to see that some are reviewing this product poorly as a result of not being able to simply open the jar and have it create flat surfaces all on its own. Here's how I use this product: 1. Prep the surface by sanding (to 220) or planing 2. Apply Aqua Coat using a plastic card and trying to press it deep into the pores of the wood. 3. lightly scrape the plastic card over the top to scrape off the excess. Be careful when you do this, you want to try to do it in 1 swipe and you don't want to press too hard because you can pull the grain filler back out of the pores. 4. Wait 45 minutes, use a paper towel to wipe up any globs you might have missed, and then lightly sand the piece with 220 grit 5. Repeat this process until the pores are completely filled. There is no 'set' number of times to recommend for this, you need to judge how many coats are necessary on an individual basis. Keep going until you can scrape your nail across the board and not have it catch on any pores. 6. Apply your topcoat of choice, if you're worried about oil based varnish adhering properly then just hit it with a coat or two of dewaxed shellac first I like this product because it retains the depth of the pores since it drys clear. This gives projects a 3D appearance instead of coming out flat which can happen when you use wet sanding + oil methods to grain fill.

I’ve used a handful of wood grain fillers over the years, and this one was honestly pretty frustrating to work with. The texture is very thick—almost jelly-like—and that made it tough to spread evenly across the surface. It didn’t level into the grain the way other fillers I’ve used have, which really affected the final result. I ended up applying three layers, and even then, the wood grain was still clearly visible through the finish. If you’re going for a perfectly smooth, glassy surface, this might not be the best choice. Fortunately, I was planning to relic this particular project, so the imperfect grain showing through wasn’t a total dealbreaker—but if I had wanted a clean, polished finish, I would’ve been disappointed. To its credit, it does harden up nicely once dry, and it sands pretty easily. But the effort it takes to apply—and the lack of complete grain fill even after multiple coats—makes me hesitant to use it again. Bottom line: If you’re okay with some texture showing through or doing a distressed/relic-style finish, this might work for you. But if you’re after a super smooth, professional-grade surface, I’d recommend going with a filler that spreads more easily and fills more effectively on the first or second pass.

The best thing about this filler for me was its soft gel texture. It's not so loose that it flows but not so viscous that it's hard to spread. I applied it easily with a shop towel, working it into the grain with a circular motion. It dried quickly - I typically gave it 45 minutes but could have probably sanded sooner. One mistake I made was that I applied/sanded 3 coats of filler before any seal coat on my finished piece and that prevented some of the end grain in particular from absorbing my finish and taking on the darker color we see when we apply our first coat of finish. That left my piece a bit splotchy until I gave it a vigorous sanding and then re-applied my wax oil finish. My plan for future will be to apply a coat of shellac or finishing oil, then proceed with the Aqua Coat filler until smooth before putting on my final finish coats. I've always found the texture of filler to be a pain - too runny or too stiff - and this product really hits the sweet spot for me.

I used oak to make some sliding doors, and wanted a smooth, painted-cabinet like finish. I knew oak would not paint smoothly, and them I stumbled across this product. "Perfect", I thought. I followed the instructions and used a plastic spreader, let it dry, and sanded it to paint. The instructions emphasize sanding LIGHTLY, but after spreading, it dried to a lumpy mess, so it required more than just LIGHT sanding. I used 220 grit until it was smooth enough to paint, and when I did, it looked like painted oak. All the grain was clearly visible and I am severely p****d at the appearance of the doors I have been working on for months. And oh, btw, if you DON'T completely sand the item, paint won't adhere to the unsanded parts. A LOT of re-work for me.

I have used this stuff for a while now on several projects and it's excellent. Fills the pores very well after a few coats and helps make the top coat smooth and deep looking.

I bought this product to fill grain on oak kitchen cabinets which I was about to paint. We did not want to see the distinctive oak grain through the new paint. We had already decided to replace the original doors with new paint-grade, maple-framed doors with MDF raised panels. So I had only to contend with the face frames and end panels, a total of about 40 square feet. I used much less than a fifth of the container on the frames and panels of our 22-door kitchen. This quart container would do at least 2 or 3 kitchens this size, doors and all. I applied the filler with a 2" putty knife, spreading thinly and diagonally across each area of grain. A little goes an awfully long way. It dries fairly quickly when on a surface, though the open container doesn't exhibit excessive drying. The product does shrink quite a bit, even in wood pores. Second or maybe third coats will be necessary for good results. Overnight drying leaves a hard surface (a good thing!). I found that any ridges I may have left between strokes could be smoothed next day with a fine scraper. 220 or 150 sandpaper on a hard wooden sanding block clogs rather quickly, especially if you work too fast. 220 sanding pads clean readily under water. We are very pleased with the surface we created with this product. Not cheap, but really does the job.

Changing the wood color to very weird color. I don't recommend it at all for guitar marketing!

Used to grain fill cedar neck and rosewood back and sides on a guitar build. Approximately 3 coats required, each lightly sanded before re-applying. Subsequent varnishing came out glass smooth.

For those that are looking to use this product...I can tell it works. I just finished doing a complete kitchen change over from 1980's yellow stained oak to white. Did many drawer fronts, as well as over 20 door fronts including 3 double size pantry doors. For all of this I used almost 4 containers. I couldn't be more pleased with the outcome. Barely a grain shows through when we looked at it from every angle in the direct sunlight. Before tackling the job I used a couple of extra door fronts as test pieces to make sure I got the best results. The first I did two coats of aqua coat clear, then primer, then two coats of milk paint and a final clear finish all applied with a paint sprayer. There were still some grains coming through. The next try, I used three coats of aqua coat clear. The fist coat very liberally applied like you'd apply car wax. Then the next coat a little less liberally but use it, and then third coat a light finish. Of course leaving time between coats to dry and sand. Sanding couldn't be easier. Then primer, paint and finish. They look like they came fresh white from the factory. I couldn't be happier with the outcome. The extra effort was definitely worth it. From one wood worker to the next.....You know that sometimes it just takes that extra step....
