Does itโs job exactly as expected - Would recommend
Thereโs absolutely nothing wrong with this flexible rubber base for gel nails. I bought this, because I had already been using a rubber base plus fiber glass to add strength to my fine brittle nails. Unfortunately, that other product was so difficult to remove. I figured getting one without fiberglass would make for easier removal, and I was right. This flexible base coat does provide more strength than plain gel polishes, but itโs not nearly as strong as the other rubber plus fiberglass product. This foundation flex performed well. I would recommend this brand if your nails arenโt as brittle as mine; the flexibility allows for some minor bending and easier removal. No weird texture. Suitable stickiness. Perfectly clear. Good product.

Great base coat
Awesome, this is 2 coats on my natural nails. I recently started growing them out and this base coat is very strong on my flimsy bendable nails. I donโt even need to put on a gel color since this color is so pretty.

Easy to use, and looks beautiful on its own
I love the ease of use and simplicity of this Foundation Flex because no additional base coat is required. There is no odor. The brush is small and straight, so I found it easier to work around the base and sidewalls of my nails without the need to use a liner brush to get in close enough. I flip my hand over just before putting it in the lamp to let gravity do its job. That ensures a nice level and balanced result. It was very easy to work with. I used two coats on my nails and after curing each layer in my nail lamp I wiped the inhibition (sticky residue) layer off the top with 99 percent ISO (Isopropyl alcohol) *because I was not topping it with another gel product, and then used one coat of regular lacquer topcoat. *NOTE*If you are doing a full gel manicure on top of the Foundation Flex coats, don't wipe the inhibition layer on the Foundation Flex. That layer serves as the surface for whatever gel you use on top of it. Once you complete your gel manicure you would only need to wipe the top coat layer if it isn't a non-wipe gel. Many gel top coats are non-wipe. Always read the product labels and directions. I bought the Light Pink and the Light Nude. Both are pink tones. The Light Pink is a cooler slightly deeper shade and it has a beautiful milky look after two coats. The Light Nude is a softer/lighter pink. Both colors look clean and natural. Both are perfect for French manicures. I included pictures of both products to help with color visualization. I love the finished look. I also love that I can use regular lacquer polishes over it when I want to change the color. As long as you use non acetone remover you can take the regular lacquer off and change it as much as you want. If you use full strength acetone it will slowly eat away at the product so that's obviously not a good idea. The finished products look really beautiful.

Lovlier Than I Imagined
It was very easy to apply. It acted just like the normal foundation coat, but with the beautiful tint to it (I chose Nude), I didn't have to add color. I applied a coat, used the gel light, then applied the second coat. Then, I just applied clear top coat -gel light-(two coats for extra strength) and after a week my nails still look really nice. They havent broken at the "corners", chipped, or broken off. I do try to wear gloves or dishes and yard work, but I'm still kind of hard on my nails. I've been happily using all Gelish items for the ten years I've been doing my nails, and this is a step up for me for a foundation coat. I'm glad I got the larger bottle because this will be my go-to nail polish during the summer when I want a polished look but without the stronger color.

Very nice
I really like this polish! My other gel polishes tend to chip, but this one did not. At about two weeks it started to peel off in big layers, and i personally prefer that over little chips. Makes removal easy. Also, my nails did not break once while wearing this. Maybe because this gel is rather thick? I work with my hands for my job so my nails break often, but coincidentally not while wearing this. 4 stars instead of 5 because applying it is so weird! The texture is extremely thick, but somehow also runny and stringy all at the same time. Took a lot of getting used to and i still need more practice. I purchased the beige color.

Love
This is a really good polish and gives a really good base if you donโt want to use a builder, this will give you builder coverage and is easy to work with. The colour is milky pink, so you can layer with pink.

Excellent adhesion
Great for long lasting gel manicures if your natural nails are flexible. Use as a base coat or a couple of layers plus top coat.

No lifting after 3 weeks!
I purchased the foundation flex to help strengthen my natural nails and it's amazing! I did apply the pro bond acid free primer prior to applying and so far I have zero lift. It also cured perfectly under the LED lamp in 90 seconds. Great product!
