It is a non-staining sealant that cures at an ambient temperature to a firm, flexible, tear-resistant rubber. DECK-O-SEAL is highly resilient and has excellent recovery characteristics after extended periods of compression or elongation. DECK-O-SEAL has outstanding resistance to most chemicals, to all weather conditions, aging, and shrinkage. USES DECK-O-SEAL is used for caulking and sealing joints subject to concrete movement to provide a firm, flexible, weather-tight seal. It is ideal for sealing joints on swimming pool decks. It is applicable for both interior and exterior use. FEATURES/BENEFITS: Highly resilient with excellent recovery characteristics. Provides permanent and uniform watertight seal. Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes. Stays flexible and won't become brittle or crack due to ultraviolet exposure. Resists abrasion, weathering and moisture - elevated temperatures will not cause discoloration. Not affected by pool chemicals. Retains joint soundness in service once it's cured and can be stretched or compressed up to 25%.

Preparation is key. Follow the directions EAXACTLY. Make sure the joint is clean and dry. Masking the joint is VERY important to avoid spills onto the deck surface. No one has a steady enough hand. Work quickly, the mfg is correct about their 1 hour pot life -- take a break after the job is done. Be careful about DIY Youtube videos. One guy suggested using a heat gun to make the product flow faster -- that would only shorten the pot life.

Deck-o-seal is NOT delivering as advertised.I have mixed and applied Deck-O-Seal around the pool many times at my home and at the properties that I own. I know how to mix and use the product. I'm very meticulous about my job, especially when it comes to my home. I see the same results whether it's in the sun or the shade.The product only lasted 4 yrs at most. Below are the pictures showing the issue.I'm very disappointed that the product did not last 4 yrs. The product company claims:DECK-O-SEAL ... is a premium-grade... tear-resistant rubber. DECK-O-SEAL has outstanding resistance .., to all weather conditions, aging, and shrinkage. USES DECK-O-SEAL ... provide a firm, flexible, weather-tight seal. Provides permanent and uniform watertight seal. Prevents uncontrolled cracking by allowing expansion and contraction during temperature changes. Stays flexible and won't become brittle or crack due to ultraviolet exposure.All the text in red is misleading at best. None of those claims seem to match with the reality of the images.I have contacted Deck-o-seal customer service and they are not taking any responsibilities. They claim that buying the product at Amazon, Ebay, etc is not fresh. They do not recommend purchasing Deck-o-seal.Time to find another product since this company does not stand behind their product!

This product has somewhat of a learning curve but you will save a lot of money if you do this yourself. A few tips: 1) Mix the two parts with one of those drill mixers, 2) Have the pool coping/deck completely ready to apply the product, 3) Do not do this in hot weather (>85 degrees) as it will set up very quickly, 4) The workable life of this is about an hour, 5) Be careful not to get this on the coping or the deck, it is somewhat difficult to get out.The finished product is durable and attractive.

I had to reseal concrete joints in my pool deck after a contractor did a slab lift. While the deck o seal two part process can be a bit cumbersome and messy, it seems to do the job.

I originally bought the Deck O seal to put in the caulking gun thinking it would be easier than mixing a bunch of cans together, but the ready mix was so hard to get out of the tube I gave myself permanent nerve damage in my thunb from trying to squeeze it out.Not only that it was sooooo sticky I couldn't get it to smooth out and look good. I finally broke down and bought the kit to mix and let me tell you it was so easy to use and turned out looking so good my pool guy asked me if I wanted a job. One tip, I put Deck O Foam (which Amazon doesn't sell,bought it at a different web site) between the pool deck and the coping stone and the Deck O Seal mix went in like melted butter.I also threw clean sand over the wet mix so it wasn't so shiny. Looks great. Be sure to measure your pool so you order enough product and it cures pretty fast in warm weather. Considering my pool guy wanted to charge me $400 to do this job, I saved $200 doing it myself! Can't beat that.

This stuff is the real deal. I used it to fill the expansion joint between my pool coping and the surrounding deck. Given the scale of the project, I used 4 gallons of DeckoSeal. The product itself is easy to work with, looks great and is very durable. My only suggestion (especially for large jobs) would be to have an applicator bottle with a larger mouth (easier to fill), a larger orifice (product is viscous), and a larger capacity. The bottle supplied with the product only holds 1/3 of a gallon so you have to keep refilling it. Otherwise, fantastic product.

First off, this product smells AWFUL. Be ready for that and when you're done, you will still smell it for the next day or two, as it smell just lingers in your nose. You absolutely must use a drill mixer, I suggest buying a cheap mixer bit that you can throw out. For prep, do everything over a sheet of cardboard and have a funnel handy that you can dispose of to get the product from the can to the applicator bottle. Be prepared to squeeze and squeeze a lot. It's a tedious installation process and you will be sore when done. However, the product seems to be very well made and while I don't have long term experience in results after 2-5 years, I'm assuming it will be good and hope to report back with more information then. I'm about to buy more, one gallon wasn't enough for me to complete the job, despite what the packaging says in how far it will go. Assume you'll have excess amounts in the can and some waste. Also, for those who buy products and plan ahead, be mindful that it has a 1 YEAR SHELF LIFE FROM DATE OF MANUFACTURE. So, wait until you're ready, don't buy this as soon as you sign your pool contract. :)

This product is not user friendly, the mixing of two parts for 10mins takes quite some efforts because of the high viscosity, not to mention the terrible smell. Another issue is it cure very fast after mixing, in May, California weather, it can’t be poured out from the can after about 50mins. I only finished half of the can because it’s the first time to use it. So my suggestion is save your time and effort, get the Sikaflex polyurethane from HD, $17 per 29Oz, supper easy to apply.
