Concrete Sealers | Concrete Hardeners


Sealhardners2Concrete Sealers & hardeners penetrate into the concrete, leaving no coating on the surface which will wear, peel, chip or scratch.

The average life of untreated concrete is just 30 years. With the application of a sealer/hardener a concrete floor becomes permanent, with no retreatment needed.

Concord Industrial Coatings are the sole Australian distributors and specialise in the application of L&M Seal Hard.

We can offer advice on what product would suit your project based on quality, longevity and top brands at the best price.

All applications are warranted.
