When is the best time of year to seal concrete?A popular myth is that concrete should only be sealed in the fall. This is true with linseed oils or discount sealers due to their short life. These products dissipate rapidly enough prior to winter to lack protection. However, quality sealers with a high solid content are guaranteed for a minimum of two winters, with others as long as four winters, making time of year a non-issue. Furthermore, sealers require that ambient temperatures, as well as the concrete and sealer, should be consistently above 40 degrees until cured. Warmer temperatures also allow for quicker and proper drying times for both the sealer and concrete after it has been properly washed. Back to Top
How often should concrete be sealed or resealed?That depends on the quality and solid content of the sealer used. We suggest every two years with film sealers and every three to four years with siloxane sealers. However, we suggest that new concrete is sealed the first and second years when protection is most needed before following this schedule.

Does the concrete really need to be pressure washed ?ABSOLUTELY! Concrete sealers demand the same considerations given other protective coatings or sealants such as paints, varnishes and waxes. All require a dirt and oil free surface. Pro-Seal will not, nor will the manufacturer, guarantee any materials applied without proper preparation. For more info, visit the prepping page.

Why was I unaware? Is sealing concrete a new process?No, but it seemed to be confined within the concrete trade. Sealing has gained popularity due to some well publicized "problems" in both residential and commercial applications. Also, it is my opinion that the concrete sold today is more prone to surface damage. Contractors and builders who share this opinion have started recommending resealing to the homeowner, further promoting its benefits and popularity. Back to Top
My driveway is a few years old and is devoid of problems. Is it safe?In my opinion, today's concrete is never out of danger. I have seen many examples of concrete failing after three or four years. Sometimes it continues every winter, and sometimes not. The lack of maintenance, the severity of winter, and use of de-icers are the common denominators in all cases. Salt crystals can build up in the pores as concrete ages and cause new problems. Please see surface damage for more information. Back to Top
Our driveway was sealed directly after placement. why should I reseal?Contractors use a variety of compounds to "cure" the concrete. Some have sealers included, while others do not. However, of the ones that do include sealers, the contractor and manufacturers themselves recommend a second coat after the concrete has had sufficient cure time.
My driveway experienced problems last winter. Can you stop the damage from continuing? Siloxane and silane sealers have an extremely good record for preventing more surface damage once it has occurred. Properly applied, these sealers offer protection for up to 5 years.
