Customer Questions & Answers
-
Question:
What is Liquid Rubber Basement and Foundation Repair Sealant used for?
Answer: Liquid Rubber Basement and Foundation Repair Sealant is designed to waterproof surfaces and seal cracks in concrete. It effectively prevents water ingress, making it ideal for damp or flooded basements, foundation walls, and external surfaces. This sealant can be applied both indoors and outdoors, providing a flexible coating that adapts to the natural movements of the structure, which is essential for long-lasting protection against water damage. -
Question:
How does Liquid Rubber sealant work for crack filling?
Answer: Liquid Rubber sealant works by penetrating and bonding to the surfaces around cracks, creating a flexible and waterproof layer. When applied, it fills in gaps and seals off pathways that allow moisture to enter. Its unique formulation allows for flexibility, accommodating minor shifts in the substrate without compromising the seal, making it effective for both small cracks and larger gaps found in basements and foundations. -
Question:
Can I use Liquid Rubber sealant on outdoor surfaces?
Answer: Yes, Liquid Rubber sealant is suitable for outdoor use. Its formulation is designed to withstand various weather conditions, including rain, snow, and UV exposure. By creating a strong and flexible waterproof barrier, it protects outdoor concrete surfaces, such as driveways, patios, and foundations, contributing to their longevity and structural integrity against the elements. -
Question:
Is Liquid Rubber Basement and Foundation Repair Sealant safe to use indoors?
Answer: Absolutely, Liquid Rubber sealant is safe for indoor applications. It emits low VOCs (Volatile Organic Compounds) during application, minimizing health risks associated with fumes. This makes it an excellent choice for indoor spaces such as basements and crawl spaces, allowing homeowners to enhance their waterproofing efforts safely while improving the overall indoor air quality. -
Question:
How do I apply Liquid Rubber sealant?
Answer: Applying Liquid Rubber sealant involves a straightforward process. Start by cleaning the area to remove dirt and loose debris. You can apply the sealant with a brush, roller, or spray system, depending on the surface area and cracks' size. Allow each coat to dry thoroughly before applying additional layers. For the best results, apply it in multiple coats to ensure a robust waterproof barrier, especially in high-humidity environments. -
Question:
Can I paint over Liquid Rubber sealant once it dries?
Answer: Yes, you can paint over Liquid Rubber sealant after it has completely dried and cured. This is important for aesthetics, allowing you to match the surface color with your home’s décor or other design elements. Before painting, ensure the sealant is completely cured to avoid any adhesion issues with the paint, ensuring a successful finish that maintains both functionality and visual appeal. -
Question:
How long does Liquid Rubber sealant last?
Answer: Liquid Rubber sealant is designed for durability, providing long-lasting protection for decades with proper application and maintenance. Factors such as environmental conditions and the quality of application can affect its lifespan. Ensuring thorough coverage and allowing adequate drying times are critical for maximizing the longevity of your waterproof barrier, particularly in areas with extreme weather or high moisture levels. -
Question:
Is it necessary to use a primer before applying Liquid Rubber sealant?
Answer: Using a primer is not typically necessary with Liquid Rubber sealant, as it bonds well to most clean concrete surfaces. However, if you are applying it over highly porous materials or previously painted surfaces, a primer may enhance adhesion. Always follow the manufacturer's recommendations based on the specific conditions of the surface to ensure optimal performance and durability. -
Question:
How long does it take for Liquid Rubber sealant to dry?
Answer: Liquid Rubber sealant generally dries to the touch within a few hours, depending on environmental conditions such as temperature and humidity. However, it's recommended to allow at least 24 hours for full curing before exposing the surface to moisture or stress. This ensures that the sealant achieves its maximum effectiveness in forming a waterproof barrier capable of withstanding various conditions. -

LiquidRubber Sealers Editorial Review
The Liquid Rubber Concrete Foundation and Basement Sealant is highly versatile and can be used on a variety of surfaces, including concrete, wood, and even for building fish tanks. The product takes a few hours to dry and may require multiple coats for maximum effectiveness. Users have reported success in using the sealant to waterproof garages and wood surfaces, with some users mentioning that a skin may form quickly in cooler temperatures. However, some users have also reported that the product can be difficult to clean and that it may not fully cure into a rubber-like membrane. Overall, the Liquid Rubber Concrete Foundation and Basement Sealant is a relatively easy-to-use, effective product for undertaking DIY waterproofing projects.
