How many square feet does one gallon of the GacoShield-GacoGrip mixture cover?

One gallon of mixture will coat approximately 100 square feet of decking surface. Five gallons of mixture will coat approximately 500 square feet of decking surface.

How do you apply the system?

Complete instructions are located on the GacoShield brochure and bucket. They are also foundhere.

My deck has been previously sealed – Will GacoShield adhere to it?

Do not apply GacoShield over water-repellant sealers. Wood sealers prevent paint or coatings from adhering to the wood. If you have sealed the wood, you must use an oxalic acid-based cleaner, such as Strip XL, manufactured by Bio Wash, to strip off the sealer. Test the surface after stripping the sealer by spraying with water and seeing if the water still beads. If the water does not bead, the sealer has been stripped. After testing, allow the surface to dry for 24 hours.

How do I clean up after application? Does the coating come out of clothing?

Use normal precautions to avoid getting the coating on your skin (wear long pants, socks, long sleeves, and work gloves). If you do get GacoShield coating on your skin, you can scrub it off with soap and water. GacoShield coating will not come out of clothing or shoes.

Where can I find a location to purchase the GacoShield?

Enter your zip code in the dealer locator box, which you can find at the top left corner of this web page. Stores within your selected search radius will be listed, along with address and phone number. Please call the stores for availability.

I live outside of your retail distribution area. Can I have GacoShield shipped to me?

We will ship direct to customers outside of our retail area. Shipping charges range from $25.00 to $60.00.

How long before furniture can be placed on the deck after the deck has been coated?

48 hours. We recommend that deck furniture have rubber tipped legs to avoid scraping the deck surface.

Can I put planters on my deck?

Yes, you may put planters on your deck. To avoid discoloring or damaging the GacoShield coated surface, planters must be up off the surface. Plant stands, rollers, or glass blocks can be used to lift planters and pots up off of the deck surface.

Can I use my barbeque on my deck?

Yes, you can barbeque on your deck. Take care to avoid any hot ashes or coals on the deck surface. If oil or soot collects on the deck surface, it may discolor. Wipe up any spills immediately.

I've been using textured black tape strips to make my stairs skid resistant, but the tape is always curling and coming up from the surface. Can I use GacoShield to provide a skid-resistant surface on pressure-treated wood stair treads?

Yes you can! No primer, tape or caulking is required. When GacoShield is applied to stairs, GacoGrip must be used.
