FAQ

Anchor-Lok is installed with conventional concrete placement practices. The sheet or fabrication is placed on forms prior to the concrete pour, allowing the lining to mechanically lock into the matrix of the concrete structure.

Yes, ANCHOR-LOK can be used for new or existing concrete construction.

Selection is based on specific service conditions of each application. ATLAS Engineering will make the determination based on chemical, thermal, physical, abrasive, and other exposure criteria.

Each thermoplastic resists a broad range of chemicals. See the Chemical Resistance Chart for specific information.

HDPE can be in service at temperatures as low as -40* F (-40* C). PVDF can withstand up to 275* F (135* C).

All seams are thermoplastically welded and backed with conductive material. Spark testing verifies the lining system is free of any pinholes or leaks. Structures can be equipped with leak detection for further assurance.

Yes. HDPE and a UV-resistant grade of PP are commonly used outside.

ANCHOR-LOK eliminates the need for concrete cure. Anchor-Lok can be placed in service as soon as concrete forms are stripped (and any seams, if present, are welded).

Structures that cannot be shipped in one piece will need to be field welded. Smaller fabrications do not require field welding.

Yes. ANCHOR-LOK can bridge concrete cracks up to ¼” wide.

No. ANCHOR-LOK is welded providing a seamless lining. The anchor penetrates into the concrete matrix and allows the lining to absorb all expansion and contraction. Eliminating expansion joints eliminates the weakest point of the lining system.

Because ANCHOR-LOK forms an integral part of the concrete structure, it can withstand over 100’ of hydrostatic head pressure.

ANCHOR-LOK is always custom fabricated. ATLAS provides drawings for customer approval before fabrication commences. If the structure can be poured with concrete, it can be lined with ANCHOR-LOK.

ANCHOR-LOK PP – Tan ANCHOR-LOK PVC – Dark Gray ANCHOR-LOK PE and UVPP – Black ANCHOR-LOK PE HMW and PVDF – White

Fabric-faced material can be provided on the grate seat, perimeter, or flange. The interface joint is reinforced before coatings, linings, and protective systems are tied into the fabric-faced material. Contact ATLAS for additional details and information.

It is 1:1. Cut equal parts of each tube and mix thoroughly.

Mix thoroughly until uniform. When in doubt, mix longer. It is often advisable to mix until warmth is generated. That means the material is beginning to react and is ready for application.

It depends on the air and/or water temperature. Please see the chart available at (data sheet). The setting of EPOXYBOND POOL PUTTY results from an exothermic reaction. Curing can be accelerated in dry areas by applying an external heat source, such as a heat lamp or hair dryer. Do not attempt to apply electric heat sources near water or damp environments.

The material will set slower. Additional time and warmth will be required.

Pool Putty will set quicker in warm air and water temperatures.

We recommend the putty remain undisturbed and free form turbulent water until set, but the pool can be used immediately after the repair is complete.

Epoxybond Pool Putty comes in Black and White. The black and white resin materials can be mixed to make variations of gray. It is important the ratio or resin to hardener remains 1:1 for proper curing.

The Rein (white tube) of Pool Putty White can be tinted. Pigments are available at some specialty craft or paint stores. Tell them you are tinting an epoxy. Add the tint to the Resin portion and mix thoroughly before mixing with the Hardener.

Epoxybond Pool Putty will not yellow, shrink, or sag.

Epoxybond Pool Paste (data sheet) is better suited for hairline cracks. Pool Putty can be used for narrow cracks but we recommend “V”ing the crack to open it up a bit before application of the putty.

Sulfur products should be heated to a temperature between 275°F (135°C) to 295°F (146°C). It is important to understand that sulfur products go through a viscosity minimum in this temperature range. The ideal temperature range for minimum viscosity is 280°F (138°C) to 285°F (141°C). Users should avoid the temptation to increase the temperature above this range to reduce viscosity, as the viscosity will increase as the temperature increases above 285°F (141°C).

Sulfur that has been accidentally overheated to a temperature in excess of 320°F (160°C) should be cooled, solidified and discarded according to all applicable local, state, provincial and federal environmental regulations.

In practice, sulfur mortars have a maximum continuous use temperature of 190°F (88°C). Above this temperature, they undergo a phase change that will weaken the product.

Ingots should be broken up and placed in a thermostatically controlled electrical melting pot, such as a home appliance cooker-fryer or oven unit or a cast iron roofer’s or plumber’s pot. Sta-Warm Electric Company, 553 North Chestnut Street, Ravenna, OH, also produces various types and sizes of melting pots.

Plasticizers help to increase the toughness and ductility of the sulfur compound.

When melted, sulfur gives off the odor of rotten eggs, which is hydrogen sulfide. It can be an annoying odor at very minimal concentrations in air. Ventilating the space for employee comfort should keep the concentration of hydrogen sulfide below the exposure limit. For exact information, air sampling is recommended.

Atlas sulfur products will flow through openings that are approximately 3/16″ (4.8 mm.) to 1/4″ (6.4 mm.).

This varies with the quantity of material poured. The surface, however, will cool immediately to a dull finish.

Standard colors are black, gray, beige, and yellow. Many additional colors are available but subject to a minimum order quantity.

ATLAS VTF Novolac Grout is capable of filling joint widths as narrow as 5/64″ to 1/8″ (2mm to 3mm).

It has very good chemical resistance to a wide range of acids, solvents, caustics, and many byproducts and cleaning compounds used in food, dairy, beverage, and other process flooring.

The optimal temperature range for the application of most ATLAS products is between 70ºF (21ºC) and 85oF (29ºC). Do not apply when room temperature is below 60ºF (16ºC) or above 100ºF (38ºC) or in direct sunlight.

Do not proceed until the ATLAS VTF SETTING BED has been allowed to set long enough to support foot traffic. Disperse ATLAS VTF FILLER over the surface of the floor. Sweep it into the open joints. Be certain the joints are full. Sweep away as much excess filler as possible. Mix ATLAS VTF NOVOLAC GROUT RESIN and HARDENER per the stated ratio. Pour the material on the floor and slowly work the materials over the joints with a rubber squeegee. Continue to work the fresh material over the joints to allow the joints to become fully saturated. Remove excess. Lightly broadcast ATLAS VTF FINE on the surface of the floor. Approximately one pound of material should cover 10 to 15 square feet. Use a Raimondi 219 Maxitinita machine with grouting paddles to power grout the floor. Remove power grout residue using a squeegee. Lightly sprinkle the floor with water. We suggest the use of a conventional “garden-type” sprayer. Use enough water to emulsify the resin and hardener. Use the Raimondi machine with nylon buffing pad (3M 5300 blue cleaning pad) to begin cleaning the floor. Remove residue using a squeegee. Repeat this step with a clean white pad (3M 4100) and remove residue with a squeegee a second time. Remove any remaining residue with a mop or cellulose sponge. Use warm water with a small amount of dish detergent and change the water frequently. Apply sufficient pressure to remove residue but not enough to remove grout from the joints. Repeat cleaning until the surface is free of haze.

Due to the wide range of tile sizes and joint configurations, it is difficult to publish standard coverage information. We do have guidelines and can assist with theoretical material requirements based on specific project information. Please contact ATLAS’ Technical Service Department for more information.
