Sikaflex 1C SL 29 fl oz Limestone - Concrete Expansion Joint Filler, Self-Leveling Polyurethane Sealant for Durable, Waterproof Concrete Repair for Driveways, Sidewalks & Industrial Use

Great product, suggest that you keep an empty cardboard box to place the loaded caulking gun Into as you move from one application to another. Make sure you use newspaper and tape along each side of the strip you are repairing. This keeps the caulk off of the driveway, etc

Best self leveling caulking available, in my opinion. Works as its intended. I also used gray color on my sidewalks. Would definitely recommend this Brand and product.

This Is a great product sold by someone devoid of a notion of how to pack same. I started using this product 5 years ago after reading test report done on salty highways by Michigan department of Transportation. This product will take salt spray, will expand to fill cracks, and will take heavy wear. However, in this particular transaction, Cartridge a did not fit into Standard Postal box so shipper bent nozzes to make them fit-- resulting in leakage of product and accelerated aging. Diagonal packing into same box would have worked fine. Applied product to finish job before heavy rains--good bonding, but messy.

This is great for filling in cracks in cement driveways/porches, especially in between slabs where you want to keep water from getting in. It's self-leveling and the limestone color is a good match. Highly recommend this product.

must have been old stock. product was watery first part of tube

The packaging was done with good environmental considerations. Thank you. However the tips need to be blunted - they almost poked through the side of the box. I expect the product to be fine - I just got it.

Great stuff for expansion joints that are missing the wood that has rotted out. Used this product to reseal them. Product is easy to apply as it level’s itself. Would recommend this to anybody who wants to DIY.

Tube exploded as soon as I started using it good product but made poorly
