DESCRIPTION
MAX ACR A/B is an epoxy-based resin system formulated as an aquarium-safe coating, casting, fiberglassing and bonding resin. It cures to a transparent clear and durable chemical resistant polymer that demonstrates excellent stability in both fresh and saltwater continuous immersion.
MAX ACR A/B is mixed 2:1 and cures at room temperature. It is low in viscosity and provides 35 to 50 minutes at room temperature. MAX ACR works well as a hermetic barrier coating for wood aquariums, terrariums and concrete ponds and fish enclosure. Upon full cure, MAX ACR is waterproof and will prevent leaching of chemical compounds from the wood or concrete substrate that is harmful to fish and reptiles. It bonds to cement or concrete ponds providing a durable sealant that is resistant to chipping or delamination. It bonds well to glass, wood, PVC and polypropylene plastics, making it a strong adhesive. 
MAX ACR A/B is also used as fiberglass impregnating resin for fabricating large plywood custom aquariums & terrariums. It bonds well to tempered glass, acrylic plastics, wood, and ceramic products. 
Measure the mix ratio accurately (2:1 by weight or by volume) and mix well to prevent leaching when in contact with the aquarium water. Cure the MAX ACR application for 2 to 3 days and then rinse with tap water before use.Use this specially formulated resin system to create a waterproof barrier when applied on concrete, wood and other materials used for fabricating wood aquariums tanks and artificial concrete ponds.
It is formulated to be an effective hermetic barrier or sealant to prevent any chemicals that can leach into the contained water that can cause dangerous pollutants to the marine animals. 
MAX ACR works well as a fiberglass impregnating resin for plywood aquarium tank construction.
Color can also be added to the clear resin using our epoxy compatible color pigment paste.

BASICS STEPS OF WOOD SEALING AND WATERPROOFING 
Ensure that the wood is as dry as possible; any excessive moisture will be sealed within the wood once it is impregnated with resin
Use a fast evaporating solvent to dilute the epoxy such as acetone or MEK
ketone based solvents). Add no more than 5% solvent by weigh or by volume to the mixed resin.
Insure that all wood surface is coated with the epoxy sealant. For best results coat the entire exposed surface area with the prepared epoxy resin mixture.
Apply multiple coats until all porosity of the wood is sealed; some grain raising can be expected upon coating.
Allow the applied coats to cure for at least 24 to 36 hours before proceeding. 
For a smoother finish, sand the cure surface just enough to remove surface gloss and removed and surface blemishes caused by the grain raising. Lightly sand the surface to remove any grain raising if desired using 280 to 300 grit sandpaper.
Fiberglassing over the seal wood for increase strength and stability
Choose the proper fiberglass weight and weave for the job. Here are some good fiberglass style.
Apply another coat of the epoxy, this time do not add any solvent to insure maximum strength development.

isdntekvideo]Determine the volume or size of the artificial reef and have a rough idea of the shape desired in mind.  In this procedure, a standard 3-inch thick, 2 pounds per cubic foot EPS Styrofoam sheets were bonded together to create a thick block 4 layers thick for the front and 2 layers for the sidewall to create an “L- shape” blank. This type of foam can be purchased from any hardware centers in 4 x 8 sheets and are commonly used for insulation.  Mixing Epoxy ResinsPlease view the following video for the proper mixing of epoxy resins.  It demonstrates the proper technique of mixing any type of epoxy resin system. The proper cure and final performance of any epoxy resin system are highly dependent on the quality and thoroughness of the mix.The resin and curing agent must be mixed to homogeneous consistency to achieve full cure.

RECOMMENDED MIXING PROCEDURE
MAX ACR will require complete and uniform incorporation of the resin and curing agent. Poorly mixed batches will result in tacky spots, uneven surface, poor adhesion and other detrimental effects. The mix ratio between the resin and curing agent is fixed and reducing or increasing the established ratio will not increase or decrease the cure rate. Physical and mechanical results will differ as stated below if this ratio is altered. To ensure trouble-free results follow this mixing procedure. 
Determine the volume needed and weigh out or proportion out two parts “Part A” to one part “Part B” by weight or by volume into a clean container. Mix using a spatula in a gentle folding method to avoid excess air entrapment. Scrape the sides and bottom of the container and mix for approximately 1 minute.To ensure complete mixing, transfer the mixed resin into another container and continue mixing for another 30 seconds. Dispense the mixed resin from this container.  Use the mixed resin within the specified working time.
To create colors use epoxy compatible colorants such as MAX EPOXY COLORANTS can be added (5% maximum) to create translucent to opaque colors.Other solid fillers such as calcium carbonate, silica sand, and clay can also be incorporated.The addition of fillers and colors should be done to the resin side or PART A and allowed to self-degas by placing the mixture in a hot water bath (120°F- 150°F) for 2 to 3 hours. and allowed to cool to room temperature. Any entrapped air bubbles will rise to the surface and can be removed by gentle surface mixing. 
Add the curing agent when the resin has cooled. Solvents such as acetone can be used sparingly to help further reduce the viscosity and aid in the application; the acetone will evaporate before the epoxy resin cures to a hard finish.Use an accurate scale if available but volumetric measuring can also be utilized as long as the mix ratio between the resin and curing agent is carefully maintained. 
The Use Of A Weighing Scale Is Highly Recommended To Ensure Proper Cure Use A Digital Scale. Purchase this scale with any of product offering and the shipping cost of the scale is free.

ARTIFICIAL REEF CONSTRUCTION
Pre- Cut the foam to the desired size and basic shape and remove the protective skin.
Bond the sheets using MAX ACR to create workable block medium and Allow to cure for 24 hours.
Fill a spray bottle (HDPE plastic bottle) with acetone and adjust output spray to a fine mist. Mist over the surface of the foam block to soften the surface
Gouge out chunks from EPS foam block to create the desired shape and contour.
Continue using the acetone mist to melt the EPS foam to achieve a rough texture. Note how the adhesive bond line used to bond the sheets begins to act like strata layers after the acetone has melted.
Allow the acetone and EPS FOAM to outgas for 24- 36 hours. Placing the foam under direct sunlight will accelerate outgassing of any residual solvent.
Mix 200 grams of MAX ACR PART A to 100 Grams of MAX ACR Part B in a clean container.
Apply the coating onto the foam to create the primary barrier coating. Color can be added at this point to help determine complete coverage of the foam.
Allow curing for 24 hours. Inspect the entire surface of the foam to ensure complete coverage.
Repeat Step 8 thru Step 10 but omit the acetone addition and add a more colorant to distinguish first coat from the second application.
This technique will give the foam further depth of field. Apply the coating onto the foam and allow to cure. The surface is now noticeable harder.
Allow curing for 2 to 3 days to allow full outgassing and cure of the MAX ACR. Placing the foam under direct sunlight will accelerate the cure and any solvent outgassing.
After the MAX ACR has fully cured, the foam surface has now developed a very rigid shell.
Rinse the entire surface with warm water several times and allow it to completely dry.
The artificial reef is now ready to be bonded to the aquarium to secure it in place. If a permanent bond is desired, use the MAX ACR as an adhesive and bond it directly to the aquarium floor and sides. If a temporary removable bond is desired use aquarium safe silicone adhesive and bond it directly to the aquarium floor or underground filtration plate.
Conditioning the MAX ACR artificial reef
After 36 hours of curing, fill the aquarium with warm water and lightly scrub the entire surface area. 
Drain the aquarium and repeat this process for at least 3 times.
Do not use soaps or detergents, just warm water or aquarium safe cleaner.
Fill the aquarium with water and begin water conditioning process.
Allow the filled aquarium to stabilize in temperature.
If the water becomes cloudy, drain the aquarium once more and repeat cleaning process.
Place the live fish into the aquarium only when the water color and pH has stabilized for 24 hours.
Cleaning
The constructed reef can be cleaned using aquarium safe cleaners or by scrubbing with a soft brush and water. 
Safe to use on both fresh/salt water.
