SANI-TRED'S FREQUENTLY ASKED QUESTIONS

The SANI-TRED System is a three-product liquid rubber waterproofing solution that works together to create permanent, seamless protection for basements and concrete surfaces:

PermaFlex – A thick liquid rubber coating that penetrates up to 1.5 inches deep into concrete, creating microscopic "rubber fingers" that anchor from within. Used as both primer and topcoat. (Coverage: 240 sq ft per gallon)

LRB (Liquid Rubber Base) – A self-leveling liquid rubber for filling cracks, joints, and depressions. Cures to solid rubber in 4 hours at any thickness with 600% elongation.

TAV (Thickening Activator) – Blends with LRB to create a caulk-like consistency for vertical application on walls and wall-floor joints without sagging.

Together, these three products join all surfaces seamlessly with no remaining cracks or joints. Unlike paint or sealants, SANI-TRED permanently bonds to concrete, never hardens or becomes brittle, and stretches with your foundation (like a roll-on swimming pool liner). The system carries a lifetime warranty and eliminates the need for excavation, drainage systems, or sump pumps.

SANI-TRED averages $1.24 per square foot, making a typical 800 sq ft basement project cost around $1,000-$3,000 (depending on substrate and condition) for complete waterproofing—compared to $10,000-$15,000+ for traditional contractor methods with excavation, drainage systems, and sump pumps. For example, a 20'x40' basement with 8' walls costs approximately $2,000-2,500 with SANI-TRED versus $14,600 with conventional systems.

No. PermaFlex, LRB, and TAV are all solvent-free and low-VOC, making them as odor-free as latex paint—safe for indoor use without overwhelming fumes. If you choose to use solvents to thin products (optional), we recommend PPE and adequate ventilation. Have questions about application or ventilation? Call us at 1-866-784-3308 before starting your project.

SANI-TRED bonds permanently to almost any construction material that is clean, dry, and free of previous coatings, foreign matter, or loose/crumbling material. This includes:

• Poured concrete and concrete block
• Brick
• Stone and Mortar
• Fiberglass
• Gunite and Stucco
• Metal (steel, iron, aluminum)
• Wood and Plywood

The key to success: Proper surface preparation is essential—surfaces must be completely clean and free of old paints, sealers, oils, or debris. Have questions about preparing your specific surface? Call our experts at 1-866-784-3308  for guidance before you start.

Absolutely! While basement waterproofing is our most popular application, SANI-TRED's versatile liquid rubber system works for dozens of residential, commercial, and industrial projects, including:

Residential: Swimming pools, fish ponds, patios, roofs, gutters, crawl spaces, garage floors, wood foundations

Commercial/Agricultural: Parking decks, grain bins, livestock facilities, feed troughs, wastewater treatment tanks, canal linings, grain elevator pits

Marine/Industrial: Boat hulls, fishing vessels, chemical plant stations, fertilizer tanks, truck bed liners, dump trailers, tank coatings

Specialty Applications: Manholes, elevator pits, tunnels, freezer interiors, car wash stations, kennel flooring

The system's ability to bond permanently to concrete, metal, and wood—combined with its resistance to chemicals, abrasion, and extreme conditions—makes it ideal for any project requiring permanent waterproofing or protective coating. See all applications →

SANI-TRED comes with a Limited Lifetime Warranty for the life of the structure when properly applied. We guarantee that PermaFlex, LRB, and TAV will not harden, crack, peel, chip, or delaminate from properly prepared surfaces—whether concrete, wood, metal, or other building materials. The warranty covers both interior and exterior applications, including exposure to high-pressure washing (up to 3,000 PSI) and perpetual water contact.

What's covered: Product defects and performance failures when installed according to our instructions on properly prepared surfaces.

What's excluded: Improper surface preparation, application over existing inferior coatings, mixing with unapproved products, extreme heat damage (over 250°F), and commercial/industrial projects (which have custom warranties).

Cleaning a PermaFlex surface is quite easy. You can use most any common detergent, dish soap, TSP (Tri Sodium Phosphate). Never use chlorine/bleach or any product containing chlorine/bleach, as they can be harmful to PermaFlex. Quaternary Disinfectant Cleaner can be used to disinfect or sanitize your PermaFlex floor.

1. Make sure the area has been thoroughly washed (TSP/water or Dawn dish soap/water), rinsed, and dried. Thoroughly scrub the area using a rags with Xylene or Acetone.
2. Apply 1 coat of LRB (Liquid Rubber Base) 240 sq’ per gal over top of the existing Sani-Tred surface.

3. If any areas require patching or profiling, mix 2-parts LRB (Liquid Rubber Base) with 1-part TAV (Thickening Activator). This will create a thickened mixture which is used for any patching or profiling of joints, seams, cracks, holes, or rough areas. Wall/floor junctions require a 1” bead of LRB/TAV mixture. Most cracks use a 3/4" bead.
4. Apply topcoat of PermaFlex (240 sq’ per gal).

We recommend you thin Sani-Tred products 15 to 25% with Xylene, or acetone.

Note: Xylene is prohibited in certain areas, check local laws.

Mix 2 parts LRB to 1 part TAV with a paddle on a drill until it has the consistency of heavy cake frosting or peanut butter. Properly mixed LRB/TAV has the consistency of silicone caulk and can be applied using a cement bag to a 1″ diameter caulk bead where the wall meets the floor and 3/4″ diameter caulk bead on most cracks. For a runnier patching liquid, use less TAV in the mixture.

Products can be applied at any temperature as long as the substrate is properly prepared. Do not apply over top of frost or ice. Sani-Tred products cure in 4 hours or less at 70 degrees Fahrenheit with normal humidity, longer to cure in colder temperatures or environments with lower humidity and 24 hours or longer in below freezing temperatures.

We recommend removing any previous applied products before applying PermaFlex to ensure the best possible adhesion. Understand that surface preparation is 75% responsible for waterproofing success of a first time application. If you want a completely waterproof basement, it’s best to remove all paint and previous coatings so you can apply PermaFlex directly to the concrete. By starting with completely bare, clean, and dry concrete free of any paint, coatings, or crumbling debris, Sani-Tred can fully adhere to the surface, penetrate deep into the pores, and harden, while remaining flexible, to fully waterproof your concrete.

LRB (Liquid Rubber Base) is a self-leveling liquid rubber that will cure throughout its entire volume at any thickness in one or multiple applications. TAV (Thickening Activator) is mixed with the LRB at a 2:1 ratio (2 parts LRB to 1 part TAV) to create a thickened mixture similar in viscosity as silicone caulk. LRB/TAV mixture is used to patch and profile joints, seams, cracks, holes and rough areas whether horizontal, vertical or inverted.

Note: TAV only works to thicken & activate LRB (Liquid Rubber Base) and has no function outside of the Sani-Tred system.

All Sani-Tred products have a shelf life of 12 months in unopened containers.

Sani-Tred can waterproof virtually any surface, even block cement walls. Block walls need 3 coats of PermaFlex. Apply two ‘prime coats’ of PermaFlex before you start patching then apply the third coat.

PermaFlex comes in 4 colors: Dark Tan, Gray, Black, and Off White. However, one of the advantages of PermaFlex is it can be painted over once it’s dried. Apply the Sani-Tred system, let it cure at least overnight and then you can paint over it to match your room’s décor. It is recommended to at least apply a test spot with the paint you intend to use.
