Learn How To Use SANI-TRED Products

The following guide will teach you how to use SANI-TRED products properly. Follow this step-by-step tutorial to ensure you never misuse our products again and achieve professional-quality results in your waterproofing and repair projects.

how to use SANI-TRED

Step One: Prepare

The first step in understanding how to use SANI-TRED products is preparing the substrate or surface. Begin by ensuring the surface is clean, dry, and free of any previously applied products, foreign matter, and loose or crumbling material. For poured concrete floors, it’s essential to perform acid etching. This process dissolves the surface of the concrete, opening its pores to allow the first coat of the product to absorb and saturate the material. Acid etching is a straightforward procedure, and detailed instructions for it are included with the materials. Proper preparation of the substrate is critical for achieving a strong bond and optimal performance of the SANI-TRED products.

Step Two: Prime

Next, prime the substrate using PermaFlex®. Apply one coat of PermaFlex® at a coverage rate of 240 square feet per gallon. Block surfaces, being highly porous, require two coats to ensure adequate coverage and penetration. PermaFlex® penetrates the substrate, curing to form a tough, tire-like surface that becomes a permanent part of the concrete. This product can be brushed, rolled, or sprayed onto the surface. Under normal conditions (70°F and 50% humidity), PermaFlex® cures to a tack-free finish within four hours or less. In cooler temperatures, curing takes longer, while warmer conditions accelerate the process. Notably, PermaFlex® also blocks over 99% of radon from entering basements. This primer is versatile and can be used on poured concrete, block, brick, stone, and mortar surfaces. Proper priming is essential to create a solid foundation for subsequent layers and ensure long-lasting waterproofing.

Step Three: Patch

The third step in how to use SANI-TRED products involves patching, profiling, and addressing specific areas such as joints, seams, cracks, and holes. Start by smoothing any rough sections and ensuring a tight seal around penetrations using the LRB/TAV mixture. This mixture is made by blending two parts of Liquid Rubber Base (LRB) with one part of Thickening Activator (TAV) to create a dense, caulk-like substance. Apply a 1-inch diameter caulk bead of this mixture where the wall meets the floor. For most cracks, a ¾-inch diameter caulk bead will suffice. The LRB/TAV mixture bonds molecularly to PermaFlex®, providing long-lasting flexibility and waterproofing. Its thickness can be adjusted during application, whether applied in a single layer or multiple coats, to meet specific patching requirements. This compound begins to cure within approximately two hours, depending on temperature and humidity, allowing you to move on to the next phase promptly. Proper patching ensures that all potential weak points are addressed and that the waterproofing system remains intact and effective.

Step Four: Topcoat

The final step in learning how to use SANI-TRED products is applying the topcoat. Apply one coat of PermaFlex® at the same coverage rate of 240 square feet per gallon. This topcoat provides an additional layer of protection and ensures a uniform, durable finish. The topcoat not only enhances the durability of the waterproofing system but also gives it a clean, professional appearance. By applying the topcoat correctly, you ensure that the entire system works together seamlessly to protect your surfaces from moisture and damage.

By following these detailed instructions on how to use SANI-TRED products, you can achieve a professional-quality result. Proper preparation, priming, patching, and topcoating are essential steps in ensuring the longevity and effectiveness of the SANI-TRED system. Remember, understanding how to use SANI-TRED correctly will not only enhance the performance of the product but also provide peace of mind knowing that your surfaces are protected with a reliable, long-lasting solution.

Final Tips for Success

To ensure the best possible outcome, always follow the manufacturer’s instructions provided with each product. Take your time to prepare the surface thoroughly, as this is one of the most critical steps in the process. When applying PermaFlex®, make sure to work in a well-ventilated area and use appropriate safety gear, such as gloves and goggles. Monitor the curing times carefully, especially in varying temperature and humidity conditions, to avoid any premature failures.


By adhering to these best practices and being meticulous in your application process, you can maximize the effectiveness of SANI-TRED products and achieve long-lasting waterproofing for your surfaces. Proper use of these products not only extends the life of your waterproofing system but also provides a safe and dry environment in your home or workspace. With the right preparation, priming, patching, and topcoating, you can ensure that SANI-TRED products deliver the durable, reliable protection you need.
