GacoDeck Kit - 3.5 Gallon plus accessories

GacoDeck allows homeowners to apply a high quality waterproof deck system over plywood, concrete, metal, fiberglass, and painted surfaces. The GacoDeck system provides lasting surface protection and waterproofing, plus a skid resistant surface that cleans up easily. Kit covers approximately 100 square feet and includes 3.5 gallons of coating, 1 tube of GacoDeckFill sealant, roller cover, brush, texture granules, tape and instructional DVD.

Suitable Plywood: Plywood should carry the trademark of the American Plywood Association. Grades "Exterior/APA A/C Group I" and "Exterior/APA B/C Group I" are suitable, as well as "Marine" grade plywood. Unsuitable grades are interior grade plywood with or without exterior glue, and underlayment grade plywood, such as "C/C Exterior," OSB, Waferboard and Exposure I markings. Do not use unsuitable grades and Gaco Deck is NOT recommended for teak, cedar or redwood due to tannin bleeding on light colors.

1 of 5 GacoDeck Stay away from Gaco/Firestone coatings – June 1, 2019
Reviewer: Orrian Rich from Ogden, UT United States  
After one winter my Gaco deck is completely pealing in sections exposed to moisture. After numerous emails to the warranty department and the Area manager, this was their response. “Per the terms of the warranty that Mr. Orrian has we reviewed the product for compliance to the Physical Properties as is warranted. The review has shown that the product meets the Physical Properties.  We meet the terms of the warranty.” During the install completely enclosed the deck area with plastic to avoid any moisture and temperature issues. I installed new 11/32 ACX plywood everywhere. I installed the Gaco deck primer per instructions, filled seams and applied Gacodeck and taped seams per instructions. I heated the area to verify temperature and humidity during and after. I allowed two weeks for the deck to dry before removing the plastic. Now the GacoDeck is not sticking to the primer in areas. The primer is adhering properly, but Gaco Deck did not adhere to the Gaco Primer.

1 of 5 GacoDeck coating for my balcony March 21, 2013
Reviewer: xiquan liang from escondido, CA United States  
The bundle package is really convenient for the userl.  The video is very helpful too.  However, the performance of the product is really.  The coating doesn't adhere or stick to the tiles at my balcony, although it stains my pant very well.  Water penetrates through the "waterproof membrane" and the membrane peels off easily.  It is absolutely not the product with 50 year warranty.


"Tiles are not a suitable substrate for the GacoDeck. Tiles are normally sealed with a coating that the GacoDeck can not adhere to.  GacoDeck was designed to be applied over Plywood or Concrete.  If there is ever any doubt about if the substrate is suitable we do have a help line available 7 days a week from 7:00am to 4:30pm PST 1-866-422-6489."

5 of 5 Works great, follow the directions! August 29, 2012
Reviewer: D.J. from St. Peters, MO, United States  
Gacodeck looks good and has held up well on my plywood deck.  Time will tell about how long it lasts, but make sure to follow all directions so that you're covered by their warranty.

The product arrived on time and in perfect condition, the "KIT" supplies were adequate and the product went on perfectly.
