Welcome to Neptune Panels

Product FAQs



Q. What are the proper care instructions for my molds?
A. First a layer of sealer should be applied to the molds to fill any small pores. When applying the panel mix do not use mineral spirits as a release agent. Keeping the molds out of direct sunlight will ensure longevity, and last do not let panel mix build up on them.

Q. When making the panels how much work time do I have to pour the mix on the mold and spread it out?
A. Depending on the consistency of your mix you will have about 10-15 mins.

Q. What should I do if the mix is too wet or too dry?
A. If the mix is too dry simply add clean water slowly a couple ounces at a time and remix. If the mix is too wet you can let it stand for several minutes in which it should start to stiffen up or you can add a small amount of Portland cement and remix.

Q. How bags of panel mix does it take to make a panel?
A. On a large mold you will end up using approx. 1 ½ bags at a ½" thick.

Q. How long does it take the mix to set-up enough to demold?
A. The Neptune panels can be demolded as quick as 4hrs.

Q. How long do I have to wait until I can use my Neptune panel after it has been demolded?
A. We recommend you wait at least 24hrs before using or hanging your panels after they have been demolded.

Q. Can I use a integral dye in the panel mix?
A. Yes, it is recommended that you check with your local supplier for proper ratios. Usually experimenting with a small handful at a time is the best way to get your desired tint.

Q. When tying rebar for the catch basin grid how far apart should the rebar be?
A. all of your steel should be 1' on center and should be propped up to keep the grid in the middle of the concrete to gain the greatest amount of flexural strength.

Q. What is the farthest apart I can wet set the Neptune frames from each other?
A. You do not want to have more than 2' in between each frame so that your structure will be properly supported.

Q. What type of concrete mix should I order from the ready mix company?
A. You will want to use a 8-9 sack grout mix. You can find the exact design in the refrence section.

Q. When do I add the pond-lok to the truck? And how much?
A. As soon as your truck arrives on site you check your concrete and then add your pond-lok to the truck. Have them mix on level ground to get a good consistency. Per yard of concrete you will add ¾ gal with ¼" of water mixed in.

Q. Is Pond-lok safe to put into the drum of a ready mix truck?
A. Yes, Pond-lok is safe to put in the truck and will not cause any damage to the fins or drum.

Q. How thick should the concrete be for the basin?
A. You want to be 6"-8" thick. Always keep a rounded shape to help with hydraulic pressure so as to reduce the chance of any cracks.

Q. What can I do if the concrete is setting up too fast?
A. If the concrete coming from the truck is drying up you need to hydrate it by asking the driver to add a few gallons of water and spin it. Hydrating the truck is usually recommended every 10-15 mins depending on the temp. If the concrete is setting up that is already out of the truck and becoming hard to work with then mixing in aqua-crylic will help bring the concrete "back to life" and will become workable again.

Q. What is the ratio for diluting the Aqua-crylic?
A. Aqua-crylic can be diluted with clean water at a 2 to 1 ratio. 2 parts water to 1 part Aqua-crylic. If you are trying to revive concrete that has gotten fairly stiff you can adjust the ratio to 1 to 1.

Q. What size rebar should be used to connect the frames together to finish the structural skeleton of the waterfall?
A. #3 (3/8") or #4 (½") rebar will work fine. The steel should be wrapped tight and double tied to create a rigid structure.

Q. Can I tie a panel to another panel beside it without tying it to the steel frame?
A. Yes, but this will produce a structural support. It should only be done to close small gaps and voids in the project.

Q. When should I start mudding the seams of the panels?
A. The best practice is finish tying all your panels together before mudding. If you start mudding the seams while people are still hanging panels the vibrations of adjusting the panels could cause the wet seams to separate or crack therefore ending up with a weak seam.

Q. I ran out of distilled water, can I dilute the color with regular water?
A. It is not recommended that you use anything but distilled water. Distilled water has no impurities in it and will bond better with the concrete.

Q. Is There a range of temperatures that I have to be aware of when coloring?
A. Yes, 50- 90 degrees is the ideal temperature range in what to color in.

Q. How long does it take the color to dry?
A. Drying time will differ according to the weather conditions in which you are coloring. Sun or shade, hot or cool, how green the concrete is, and if wind will play a factor.

Q. Do I have to color my project immediately or can I wait?
A. You may wait to color your project as long as you do not seal it. When you are ready to color you will need to make sure that you remove any dust or debris from your project so you will get a good bond with the color.

Q. Do I need a permit or engineered plans to build my water feature?
A. You will need to check with your local building codes and/or building inspector.
