NEOPOND SEALANT APPLICATION GUIDELINE

Step 1 - Inspect the surface All surfaces must be structurally sound, clean, dry, and free from anything that would prevent proper adhesion. If not using kiln dried wood, be sure that the new wood is sufficiently dried (less than 15% relative humidity), this can take weeks to months (kiln dried wood should already be dry enough). Treated wood should be thoroughly cleaned to remove treatments from the surface to which you will apply your Liquid Rubber Solution and allowed to dry.
Step 1 - cont'd Put a couple of drops of water on the surface of the dry wood. If it absorbs it is dry enough, if it beads up there is too much moisture and it needs additional drying time. Concrete must be cured for a minimum of 28 days. All flaws should be repaired and cured prior to coating.
For Concrete Knock down high spots and make necessary repairs prior to application. Look for cracks, efflorescence, spalling/pitting and damp spots. Concrete should be etched using Liquid Rubber Concrete Etch or equivalent, power washed and allowed to fully dry. Be sure to perform a moisture test on the concrete prior to application. Refer to moisture test guidelines.
For Wood Look for rot, splitting, checking, etc. and replace if necessary. Blight and biological growth must be removed using Liquid Rubber Deck and Patio Cleaner. Secure raised nail heads, deck screws and loose boards. Pre-fill imperfections such as screw holes, knots, and splits in the wood with a high-quality wood filler, or Liquid Rubber Sealant & Adhesive (or equivalent).
For PVC, Fiberglass and Metal Look for cracking/crazing, chalking, exposed fibers, damage and rust. PVC, fiberglass and metal should be scuffed with sandpaper to remove gloss, prior to cleaning and primer application.
For EPDM Look for cracking/crazing, oxidized/chalky surface, shrinkage (pulling away at the edges), blistering and damage, and repair as necessary.
Step 2 - Clean the surface Clean the surface to be coated with Liquid Rubber RV Roof Smart Cleaner, by power wash or high-pressure nozzle on a garden hose or a combination as required and as available. For EPDM, fiberglass and PVC it is recommended to give the surface a wipe with a white rag right before you prime the surface, to "re-energize" the surface.
Step 3 - Details Bridge cracks, cold joints, and transitions (floor to wall) using the 3-course method of Liquid Rubber Multi-Purpose Primer - Liquid Rubber 4” Geo-textile - Liquid Rubber Multi-Purpose Primer. Apply a generous 6” wide coat of Liquid Rubber MultiPurpose Primer along the areas and while still wet, embed the Geo-textile fabric, fuzzy side down. Smooth out wrinkles and apply a second coat on top. Allow to dry before application. Approx. 1-2 hours. For EPDM Liners use Liquid Rubber Seam Tape instead.
Step 4 - Masking Tape-off, block off or otherwise mask areas that are not to receive coating. Remove while the coating is still wet.
Step 5 - Application Prime the surface and allow to dry. Coat EPDM Primer as soon as possible after drying. Using a 3/8’’ (10mm) roller, apply approximately 3-4 coats Liquid Rubber NeoPond Sealant. Allow at least 4-6 hours drying time between coats. You can recoat after the material is dry to the touch with nothing wet underneath and it is uniform in color. Apply each new coat at a different angle to the previous coat to ensure even coverage. For rough surfaces, edges and corners apply using a nylon/polyester brush.
Step 6 - Inspect Inspect for pinholes, blisters, thin spots, or other flaws. Recoat as necessary.
Step 7 - Protect Allow 3-5 days before filling your pond or using your fountain/water feature.
Coverage Apply a minimum of 1 gallon per 40 ft² (3.7sqm/G) final thickness. Should require 3-4 generous coats. Use up all required material.
CAUTION: - For Fish and Plants When first filled, wait 24 hours, wipe the sides, drain and refill to remove surfactants. Repeat if necessary. Do not add fish or plants until the coating is uniform in color and the water is clean. Be sure to test the water for proper PH levels acceptable for your type of fish and adjust as necessary.

APPLICATION TIPS AND TRICKS

* Apply using a 3/8 (10mm) roller, brush, or paint sprayer.
* Apply to a clean, dry surface that is free of silicone, loose paint, rust, oil, grease, coal tar, or other anything that would hinder adhesion.
* Remove silicone caulking and replace with Liquid Rubber Sealant & Adhesive (or equivalent).
* Apply when the temperature is above 10˚C/50˚F and rising (including overnight temperatures).
* For extra adhesion, performance, and longevity and to create a moisture vapor barrier, it is necessary to use 1 heavy coat of Liquid Rubber Multi-Purpose Primer.
* Be sure to test the water for proper PH levels acceptable for your type of fish and adjust as necessary.
* Apply each coat in an alternate direction to the last coat to ensure even coverage.
* Apply next coat when dry to the touch with nothing wet underneath and is uniform in color. (typically 4-6 hours)
* Typically cures within 72 hours. (3-5 Days after last coat before filling/using)
* Avoid applying in direct intense sunlight.
* Do not allow to freeze until fully cured.
* Do not apply in wet conditions (including fog and dew) or if rain is forecast within 24 hours.
* Avoid contact with solvents and solvent based cleaners, adhesives, and paints.
* Remove painter's tape while the coating is still wet.
* May blush in the presence of water. This is due to local water content and does not affect the performance of the coating.
* For best results remove existing paints/coatings and apply directly to the substrate. (some paints and coatings will not be compatible. Loose/flaky paint may be an indication that the existing paint/coating is not well bonded and therefore your Liquid Rubber solution may fail if applied over it instead of directly to the substrate. Oil based paints, enamels, epoxies, powder coats can be difficult to bond to.

    5.0 out of 5 stars You Will Love This Stuff as Much as You Love Your Pond!
    Reviewed in the United States on June 1, 2022
    We had an older pond and had a pro pond builder come out and re-do our pond and add a 2nd one with stream in middle, was great! but that was 25 to 30 years ago! The ponds were made of concrete that had aged well but needed help, to be excepted after that long in freezing winters and hot hot summers. I went on a internet search for the right solution for 2 over 65 people to tackle, I was not digging them up or filling them in, I came across a lot of information! Some good, some what are you talking about junk. It was so intimidating, then I found Liquid Rubber! I was so impressed in the fact that
    1. the name was just what it was
    2. The names for the products were for what it was to be used on, we got the NeoPond, because it was for Ponds and safe for fish and plants
    3. I could actually understand the directions.
    We also bought the Liquid Rubber Multi-Purpose Primer, it said it was for Concrete and wood, great, done! I wish we had pictures of before, but I do have after's to share. If you need help just give them a call ask for Trevor he is great. Love this product and company. Included a ideal we did also. We put our filter, UV light, fountain combo into our sunk pump for water fall into the lid of the bucket of sunk pump, We cut the shape out of top, tested it in swimming pool and worked great! This hid both, as they are under water and black In top pond we used the Liquid Rubber to paint the old bottom of a bird bath to set the filter for that pond on, Now we are just waiting for the curing time to do its thing, add water and enjoy! PS I was going back and forth about wanting the pond to be blue again, but LOVE the black, everything, fish, plants & frogs show up better! and other stuff doesn't.
