convenient solution for sealing and protecting various surfaces
The BDYLYS Invisible Waterproof Agent is a transparent liquid waterproof coating designed to seal and protect surfaces from water damage. It’s marketed as a versatile product that can be used for a variety of purposes, such as repairing leaks, sealing cracks, and providing waterproofing protection on various surfaces. Here’s a detailed review of what you can expect from this product: ### Pros: 1. **Versatile Application**: This waterproof agent can be used on a wide range of surfaces, including concrete, metal, tile, wood, and more. It’s suitable for both indoor and outdoor use, making it a versatile tool for home repairs and maintenance. 2. **Transparent Finish**: The liquid dries clear, making it ideal for surfaces where you want to maintain the original appearance. This is especially useful for areas where aesthetics are important, such as tiles, wood finishes, or decorative surfaces. 3. **Easy to Apply**: The product is typically easy to apply with a brush, roller, or spray, depending on the surface area and location. It’s designed to provide even coverage with minimal effort, making it accessible for DIY users. 4. **Waterproofing and Sealing**: Once applied, the coating forms a waterproof barrier that helps protect surfaces from moisture, leaks, and water damage. This can be particularly effective for sealing cracks, joints, and seams that are prone to leaking. 5. **Durability**: The sealant is designed to be durable and long-lasting, providing ongoing protection against water intrusion. It can withstand exposure to the elements, including rain, snow, and UV rays, making it suitable for outdoor use. 6. **Quick Drying**: The product often features a quick-drying formula, allowing for faster completion of projects. This is beneficial for time-sensitive repairs or when applying multiple coats. ### Cons: 1. **Limited Coverage**: Depending on the size of the area you need to cover, the amount of product in one container might be limited. Larger projects may require multiple containers, which could increase the overall cost. 2. **Surface Preparation**: For the best results, the surface must be clean, dry, and free of dust, oil, or other contaminants before applying the waterproof agent. This preparation can add extra time and effort to the process. 3. **Not Suitable for All Leaks**: While effective for many types of leaks and surface sealing, it might not be sufficient for major leaks or areas with significant structural damage. In such cases, more extensive repairs may be necessary. 4. **Longevity Concerns**: While the product is designed to be durable, the longevity of the seal can vary depending on the surface, environmental conditions, and application method. Some users may find that reapplication is needed sooner than expected. 5. **Chemical Odor**: Like many sealants, this product may have a strong chemical odor during application. Proper ventilation is necessary when using it indoors, and users should be mindful of potential sensitivities. ### Final Thoughts: The BDYLYS Invisible Waterproof Agent is a versatile and convenient solution for sealing and protecting various surfaces from water damage. Its transparent finish and ease of application make it an attractive option for DIY repairs and maintenance projects. However, it’s important to consider the specific requirements of your project, including the size of the area to be treated and the nature of the leaks or surfaces involved. For general waterproofing and minor leak repairs, this product offers a practical and effective solution, though it may not be suitable for more significant structural issues.

So far, so good
Last year I put some type of waterproofing spray on the handles of my well used, well-aged wheel barrel. This spring it has a sort of hair hanging off of them. So I scraped and sanded that old, useless product and brushed the first coat of this on them. This is a fairly thick substance like it shows in the pictures. It went on easily enough on those handles and I will be putting another coat on them next spring...I ran out of good weather. I have high hopes that this time I'm not wasting my time or money! I will try to update next spring if this first coat is coming off. I think it will work fine. Then I'm going to do my tree saw handle and my garden knife handle, just to keep them in good condition.

Magic Diamond Coasters are useable now
"Magic diamond painting" is attaching colored rhinestones to make patterns, and I made some sparkly cheerful coasters to protect my wood table from my refreshing beverage. Problem is, the adhesive used for magic diamond painting, and all the sealants I've found, are water soluable -- basically clear Elmer's Glue (TM). This sealant was very easy to apply with an artist's bristle brush and the brush cleaned up nicely with warm water. I applied two very thin coats and the result is crystal clear. If the coating was clear when wet, it stayed clear when dry; if it was translucent (such as a glob between rhinestones), it got a little clearer but was still visible. It dried in the 12 to 24 hours, per the instructions. It sheds water from a faucet, and keeps the diamonds in place nicely when I let water set on it for a few hours. Most sealants aren't completely clear so not suitable for putting on sparkly things, but this one is if used properly. I also used only a tiny amount and still have enough left to coat hundreds of additional coasters if I should get the urge. I might coat a few magic diamond paintings (they brighten the dark hallways in my almost-windowless apartment), and am looking around for other uses. I'm very happy with this water resistant sealant, and happy to be able to use my sparkly coasters at last.

Amazing, easy to use
I used a small amount, to test, on a coaster that I painted with gouache. It dries clear as long as you use a small amount. I used a small brush, but switched to a small sponge brush because my gouache isn't completely flat, it has some texture and it is a bit delicate. It turned out wonderful. It does small a bit when you are using it, so I moved to the kitchen so that I could turn on the fan above the stovetop to try and dissipate the stinkiness a bit. But it really lingered, so I made some toast to try to mask the smell, it worked. But wow, it was powerfully smelly, almost as bad as rubber cement. Then I used a small amount on the tiles near my bathtub. I put a little bit under where two of the tile were lifting a bit and then to stick and seal them to the bathtub. So far so good. If it doesn't work, I will know soon, I guess. I am wondering if this stuff could be used to mosaic with tiles, beads or mirrors. I might give it a try on a small piece, in case it fails. But I do think it is working so far. It dries really clear except when you use a lot it looks pretty cloudy.

Thin stuff
This sealant is a lot runnier than I expected, given all the suggested uses for it. The viscosity is like runny painting medium. Mod Podge and Elmer’s-type PVA glues are thicker than this. I’ve applied it with foam brushes over acrylic painted canvases as a finishing top coat. Did it provide a smooth barrier? Yes. A lot of fumes and stickiness? Nope. Does it dry crystal clear ? No, not perfectly. When I need a clear gloss coat, I tend to go for glossy painting medium or a water soluble gloss varnish. So the fact that this stuff’s not crystal clear isn’t really a let down, just something worth mentioning. Would I paint a roof or some outdoor furniture with this stuff or use it to patch a leaky ceiling ? No, I really wouldn’t. It simply doesn’t seem hefty enough to hold up to a lot of weathering and exposure. But for some craft applications, it could be useful.

Odorless when dry
I am using this for hand made wooden drink coasters. Instructions on jar are easy to read and follow. I used a sponge brush to apply it. I did get it on hands as I was working it washed off easily with hot water and soap. My second coat I did apply too thick so brush strokes are visible just be aware of that when using. Last photo is the difference between a unsealed coaster and one I sealed with this waterproof patch & sealant after washing with soap and hot water. The jar says it is odorless and it is when dry but it does have a slight rubber/plastic smell when wet. But it is a light smell not noticeable unless you put your nose near jar or project. I took a star off because I had a hard time trying to close jar after use. Every time I would push lid down it would pop back up.
