  • Landscaping; maintain desired appearance of coloured concrete, no seepage


    Dear Sirs,

    In my business, Site Specific Works, we design and manufacture concrete into functional objects such as furniture and water features for our customers' landscaping needs.

    We first used Seal-It Top Seal in March of 2001 and we continue to use it as there have been no signs of decreased performance of the sealant once applied to the concrete. The sealant does not change the visible appearance of our creations and they maintain the look they were meant to have. Our pieces sometimes incorporate an add mixture for colour, Top Seal maintains the true colour through all weather conditions. We will continue to use Seal-It Top Seal on all our projects.

  • Rough tiled floor; difficult clean made easy


    Dear Sir: We recently applied your product "Top Seal" as a protective floor coating in our restaurant. The floor has been "tiled" with a "sliced" paving stone in keeping with the paving stones used by the city for the sidewalk outside our restaurant. After a few maple syrup spills, we realized that cleaning this rough surface would be challenging.

    I was surprised how fast and easy it was to apply your product. We just sprayed it on in minutes with a small bottle sprayed. The addition of Seal-It Top Seal has created a surface that is easily cleaned. We sweep and wet mop the floor every day, and because of Top Seal, we get a better and easier clean. And there does not seem to be any wearing of the Top Seal, as water still "beads" on the floor.

  • Roofing: Extend the life of asphalt and tar roofing systems


    Dear Doug,

    I wanted to get you this information regarding your Seal-It products. We have been using your concrete sealant to make our new colors, using mineral life, completely permanent. Using 4,000 psi of water will not remove the color.

    However, I wanted to tell you about some other areas that we have used “Top Seal” in a different way. Southwest America is also a property management company, so We have used the product on our own asphalt shingles, which has taken care of any leaks That we had. A friend of mine used it on his garage roof two years ago to stop all the bad leaking. It’s two years later and no leaks, except he just put on a new roof because the Previous leaking had destroyed the wood base.

    In another instance we had a 10,000 square foot building with a flat, rock/gravel,Tar roof that had a 10 square foot x 10 square foot area that was leaking water inside. We Did not want to replace the entire roof so we tried the “Top Seal” on this area, spraying over the rocks and tar where we felt it was leaking. After the next rain there was no more leaking, and now 1-1/2 years later, still no leaks.

    I believe your product has exceptional uses in other areas you have not even tried,this being two of them.

    I had a friend who used your “Top Seal” on his new restaurant tile that had already been stained by syrup from pancakes. It took him one hour to clean it then he applied “Top Seal” to the entire restaurant floor. Guess what? No more stains, plus an easy cleanup each night.

    I would highly recommend “Top Seal” to anyone who would appreciate a one-time application on something that works. I’ve got another 10 gallons in our storage area for the apartments and I’m sure that I’ll have more uses for the product shortly. Thanks again for all your help and support. You’ve got a great product. You only need to let more people know what you have.

  • Manufacturing? Insure a dry environment


    Dear Sir:

    Re: Use of Top Seal on Concrete Block Silos

    At the Manville facility in Innisfail we manufacture fiberglass insulation. Raw materials used for glass making are stored in silos approximately 18 ft. in diameter and 50ft. high. These silos are constructed of insulated concrete blocks that are installed with no mortar and are held together with steel hoops. The outside and inside surfaces are coated with a thin, brushed on water/cement mixture in several layers. The original and subsequent coatings had a water sealing additive intended to make the coating watertight. Our raw materials are dry granular products which in nearly all cases will take up any moisture present and form into lumps. Both the lumps and the increase in moisture content cause problems in our process.

    Soon after the silos were put into service, moisture problems began. Filling of visual cracking and several recoats of the outside failed to stop the water penetration. Each year we randomly test for water tightness by applying a water spray at the top of the silo wall, allowing the water to run down the wall for a minimum of 12 hours. The normal result was darkening of the outside surface followed after a number of hours by darkening of the inside surface starting at the lines of the joints between blocks, and spreading from there. If there is a surface crack on the outside that has not been filled, the migration is quick and usually results in beads of water on the inside.

    In the summer of 1987 we were introduced to the Seal-It products and looked at Top Seal as a possible sealant for our silos. Top Seal was applied to an area of one silo wall and a spray test done. The immediate observations were that in the treated areas the water would bead up and run off. The treated areas did not discolour and at the end of the test there was no general discolouration on the inside. Some surface cracks were found as a result of the test. Based on that test we decided to coat all of the silos and did so in the late fall of 1987. Water testing in the spring of 1988 had good results but showed areas that the contractor had missed. The difference in colour of the wetted surfaces made those areas obvious. Water testing in 1989 gave the same good results.

    The application of Top Seal has not been an end-all solution to our problems, but it has greatly improved our situation. The Top Seal is not intended to and will not fill cracks. Any visual cracks must be filled with a suitable material. But areas without cracks have remained watertight. Based on the results we have seen up to now and the 10 year warranty you have given us, I feel we have spent our money wisely.
