Apply minimum final thickness of 1 gallon per 40 sq ft (3.7 sq/m). It should require around 3-4 heavy coats to achieve a 30 mil. (0.75 mm) (DFT) membrane. 200 sq ft per 5G pail.

For Step-By-Step Guides Specific to Your Project
Make sure your surface is clean, dry, and free of dirt, silicone, loose paint, rust, oil, grease, coal tar, or other contaminants. Apply using a 3/8 (10mm) roller, brush or paint sprayer. Temperature should be above 10˚C/50˚F and without rain or dew in the forecast when applying.
Etch concrete prior to application.
Apply each coat in an alternate direction to the last coat to ensure even coverage. For extra adhesion, performance and longevity and to create a moisture vapor barrier, use 1 heavy coat of Liquid Rubber Multi-Purpose Primer or Liquid Rubber EPDM Primer. We recommend applying a test patch before full application.
Apply next coat when dry to the touch with nothing wet underneath and is uniform in color (typically 4-6 hours).
Curing time depends on humidity and temperature however typical cure time is 72 hours (3-5 days after last coat before filling/use). Do not allow to freeze until fully cured.
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. Contact your Liquid Rubber technical representative for further direction.) Avoid contact with solvents and solvent based cleaners, adhesives and paints. Do not combine black products with colored products.
Use Deck Cleaner on Wood. Use EPDM Primer for EPDM pond liner. Reinforce seams, joints, cracks... with Geo-Textile or Seam Tape.
Use Liquid Rubber Caulking for gaps, cracks and around penetrations.
Be sure to test the water for proper PH levels acceptable for your type of fish and adjust as necessary and to cycle the water to remove surfactants before adding fish.
The primer, tape & 10 coats of sealant went on w/o a hitch, but waiting to see how it holds up. First customer service agent gave me a valuable tip re etching before primer.
Just follow your directions and curing times,give the old liner and new wardrobe.....help to seal and fix holes that may have happen during the winter months ! Made just for your Koi pond ,fair price and they ship out fast ,most of all fish friendly just allow the the full drying and curing times !
Traveled way farther than expected even with heavy coats. Building a concrete koi pond and I rolled it super heavy twice and then did two heavy stay coats. I may have enough to put one more final as well.
I had a seam failure in EDPM liner and had limited success with other products I now have Koi back in pond and am happy to say water level is holding! Only time will tell, I only wish I would have used this product line on first installment, when liner was free of pond crust.
The pond was stripped of a previous product that did not perform well.
Liquid rubber was applied and performed exceptionally well
