For waterproofing a 1″thick plywood aquarium 8′long x 3′wide x 2′deep with the front viewing pannel being plexi, What do I need to make a Black waterproof liner? I figured 76 square feet of inside surface.

Answer:

1. The first thing you would do is prepare the substrate. Make sure the substrate is clean, dry, free of any previous applied product, and foreign matter.
2. Prime the Plywood with 1 coat of PermaFlex (240 sq ft per gal). Prime the acrylic with 1 coat of 2-part epoxy primer. The prime coat of PermaFlex will penetrate into the plywood then cure tough as a truck tire inside the plywood to achieve permanent adhesion. The 2-part epoxy primer is used to better adhere to the acrylic.
3. Patch and profile any plywood joints, seams, cracks, holes, etc… using LRB/TAV mixture at a ¾” bead. This mixture is 2 parts LRB to 1 part TAV. LRB/TAV mixture will molecularly weld to the prime coat of PermaFlex and permanently adhere to the epoxy primer.




4. Apply a coat of LRB (Liquid Rubber Base) to the interior of the tank to create a thick impervious membrane (80 sq ft per gal) 20 mils thickness. LRB will cure at any thickness. The LRB membrane will overwhelm any imperfections within the plywood, guarantee an absolute seal, allow ultimate flexibility, and durability. This membrane will molecularly weld to the previous applications. LRB can also be thickened to any viscosity by mixing it with TAV. This will give you thicker vertical cling if the tank can not be flipped onto its side.
5. Topcoat using 1 coat of PermaFlex (240 sq ft per gal) which will molecularly weld to the LRB membrane.

If VHO lighting or any other intense UV lighting will be used or would like a special color, apply 1 coat of a good 2 part epoxy paint. This paint will give you the color desired and extreme UV resistance. This coat will not aid or inhibit the waterproofing/sealing of the aquarium. Wash the Sani-Tred surfaces before filling the tank with water.

I’m from Langkawi, Malaysia. We operate and maintain a five star luxury international resort. We have 5 nos of water pond with tiles finish floor. We notice pond water leak 2 to 4 inch a day. Do you have a product to seal our ponds keeping the tiles finish intact (probably a clear or transperent color of water proofing material) Do you have distributor in Malaysia? thank you

Answer:

We ship direct to Malaysia. The only way to permanently waterproof/seal the ponds but keep the look of the tile is to remove the tile, waterproof then re-set the tile.

The other option is to waterproof over the tile.

I’ve got a fountain (this one in fact http://www.lowes.com/lowes/lkn?
action=productDetail&productId=155068-19811-F30276DA&lpage=none) that was left out too long this season and ended up freezing. The bottom inside of the fountain cracked and is now letting water flow down and out of the base. Can Sani-Tred be used to seal this? Could I use it on the underside of the fountain so it\’s not visible? Thank you!

Answer:

Yes,

Cracks-

To permanently waterproof/seal hairline cracks after removing any previously applied products – apply 2 coats PermaFlex.

To permanently waterproof/seal cracks wider than hairline after removing all previously applied products-

Prime w/PermaFlex,

Fill/seal using the LRB/TAV,

Surface coat w/PermaFlex.
