Customer Questions & Answers

Question:
What surfaces can I use LastiSeal Brick & Concrete Sealer on?
Answer: LastiSeal Brick & Concrete Sealer is designed for use on various surfaces, including brick, concrete, and pavers. This versatility makes it ideal for both interior and exterior applications. It effectively waterproofs and strengthens these surfaces, ensuring they remain durable and aesthetically pleasing. Whether you’re looking to protect a driveway, patio, or basement floor, this sealer is an excellent choice to enhance longevity and resilience against environmental factors. -
Question:
How does LastiSeal Brick & Concrete Sealer work?
Answer: LastiSeal Brick & Concrete Sealer penetrates deeply into the surface of brick and concrete, forming a protective barrier against moisture and other harmful elements. The formula is designed to bind with the materials at a molecular level, which enhances strength while preventing water and staining agents from seeping through. For example, applying LastiSeal can help protect your driveway from freeze-thaw cycles or staining from oil spills, thus maintaining its integrity and appearance over time. -
Question:
Is LastiSeal Brick & Concrete Sealer suitable for indoor use?
Answer: Yes, LastiSeal Brick & Concrete Sealer is suitable for indoor applications. When applied to surfaces like basement floors or interior brick walls, it helps prevent moisture damage while also enhancing the aesthetic appeal of the space. Not only does it guard against mold and mildew, but it also strengthens the material. Homeowners often use it in high-humidity areas like laundry rooms or bathrooms to maintain the quality of the brick or concrete structures. -
Question:
Can LastiSeal be used on outdoor surfaces?
Answer: Absolutely! LastiSeal Brick & Concrete Sealer is expertly formulated for outdoor surfaces. Its waterproofing capabilities protect against rain, snow, and ice, making it perfect for patios, driveways, and walkways. This ensures that your outdoor spaces remain not only beautiful but also structurally sound over seasons. Regular use can prevent degradation caused by weather, saving you from expensive repairs later on. -
Question:
How long does LastiSeal take to dry?
Answer: LastiSeal typically requires approximately 24 hours to dry completely under ideal conditions. However, drying times can vary based on factors such as humidity and temperature. For best results, it's advisable to apply the sealer when temperatures are moderate and humidity is lower. Space outdoor applications to avoid rainy days can also enhance the efficiency of your sealing project. -
Question:
Can I apply LastiSeal in multiple coats?
Answer: Yes, applying multiple coats of LastiSeal can provide extra protection for your surfaces. Once the initial coat has dried, a second coat can reinforce the waterproof barrier and further strengthen the material. This is especially beneficial in high-traffic areas or surfaces exposed to severe weather conditions. Always make sure to follow the manufacturer's instructions regarding coat application for optimal results. -
Question:
What is the coverage of LastiSeal per gallon?
Answer: LastiSeal Brick & Concrete Sealer covers approximately 100-150 square feet per gallon, depending on the porosity of the surface. For highly absorbent surfaces, the coverage may be on the lower end of this range. Proper preparation of the surface before application, such as cleaning and allowing the material to dry, will help achieve the best remaining coverage and effectiveness during application. -
Question:
Is LastiSeal environmentally friendly?
Answer: Yes, LastiSeal Brick & Concrete Sealer is formulated to be environmentally friendly while providing high performance. It minimizes environmental impact compared to other sealers containing harsh chemicals. This makes it an ideal choice for homeowners looking to protect their surfaces without harming the eco-system, enabling you to achieve long-lasting results in an environmentally conscious manner. -
Question:
How do I apply LastiSeal Brick & Concrete Sealer?
Answer: To apply LastiSeal, start with a clean and dry surface. Use a roller, brush, or sprayer to evenly coat the area, ensuring even application. Apply a thin first coat and allow it to dry before applying additional layers if desired. Optimize your application by working in manageable sections and avoiding pooling of the product. This method ensures the best seal and protection for your brick and concrete surfaces. -

RadonSeal Sealers Editorial Review
LastiSeal Brick & Concrete Sealer is a nano-chemical, penetrating sealer that can be applied to porous surfaces/materials such as poured concrete, concrete blocks, brick, mortar, pavers, limestone, sandstone, etc. If applied properly, it has a warranty of up to 15 years. The coverage area would depend heavily on how porous the substrate is. It works by being absorbed by a porous surface so paint will simply repel the sealer. The product should only be applied to a bare and porous substrate. If you’re in the line of work of brick sealing, concrete block sealing, or anything of that nature, this is the product for you. It helps stop wind-driven rain from penetrating brick/block, helps prevent brick pitting, and extends the life of some paints. The drawbacks to this product are that it is costly and may not work if you are just trying to avoid staining concrete. Some customers report that it is getting mold and mildew growing on their brick pavers just six months after applying the product. However, other customers reported outstanding results, including one customer who applied it to their chimney to renovate a sporadic leak and it worked flawlessly.
