Preparing Concrete Surfaces for Flex Seal Application
Before you apply Flex Seal, you need to prepare the surface. I’ll show you how to get your surface ready for the best results.
Cleaning the surface is the first step. Remove all dirt, dust, and loose debris. A clean surface helps Flex Seal stick better and seal more effectively.

- Sand off any rust or rough patches
- Ensure the surface is completely dry before application
When applying Flex Seal, the surface condition is key. Dry surfaces work best, but it can also work on slightly damp areas. Make sure to prepare cinderblocks, driveways, and basement walls carefully.
| Surface Type | Preparation Method | Notes |
|---|---|---|
| Smooth Concrete | Light sanding | Improves adhesion |
| Rough Concrete | Thorough cleaning | Remove all loose particles |
| Rusty Surfaces | Sandblasting | Minimum 70 CFM @ 90 P.S.I. |
Pro tip: Dry the surface with a blower before applying Flex Seal. This step helps your concrete repair work better.

Maintenance Tips for Flex Seal Treated Concrete
Keeping your concrete surfaces in good shape after using Flex Seal is important. I’ll give you some useful tips to make your Flex Seal last longer and keep your concrete safe.
Regular care is key to keeping your concrete protected for a long time. Here are some important steps to keep your concrete looking great:

Remember, Flex Seal is great at fighting off the weather. I suggest reapplying it every 2-3 years, depending on how much it’s exposed and how much traffic it gets.
Important maintenance steps include:
- Remove dirt and debris before checking
- Find weak spots in the seal
- Fix small damages right away
- Make sure water can drain away from sealed areas
Temperature and weather can affect how well your seal works. In very hot or cold places, you might need to check and reapply more often.
Pro tip: Always work in a well-ventilated area. Wait 24 hours between coats for best results. It takes about 48 hours for the seal to fully cure, giving you strong protection against moisture and damage.
