1-gal. Invisible Concrete Sealer, Waterproofer plus Densifier

This is a very good DYI product. Moved into a 25 year old home with a very large exposed aggregate driveway, which had never been sealed. The driveway was showing signs of age with mold, stains, and typical discoloration. After obtaining proposals and quotes from contractors, I decided to do the work myself. I have used gloss surface coatings on other driveways, and while they looked great after the initial application, it was an annual project to maintain the results. LS 9500 provided the penetrating, chemical bonding sealer which would also strengthen the surface of the aggregate, that I was looking for. LS 9500 was easy to mix and apply, and I am very happy with results. Here are some tips to consider when using this product: 1. Power wash and completely clean the surface using a bio-friendly concrete cleaner 2. Remove all stains, oil spots, and any other surface contaminates using a commercially available concrete stain remover 3. Plan to apply the product on a completely clean and dry surface, during a time with no wind and temperatures in the 70's (I found early mornings worked the best) 4. Select a hand garden sprayer of your choice (A back pack sprayer can be used for a large area, but any size will do) 5. Measure the amount of LS9500 per the instructions ( I used 4 plastic containers with equal amount LS9500; so each container could be mixed with each gallon of water 6. Dress in long pants and work shoes, to avoid coming in contact with overspray 7. Spray LS9500 mix in a evenly applied sweeping fashion, with just enough coverage to dampen (wet) the concrete (not so much as to puddle the surface) 8. Work your way from your starting point to your finish point, keeping the concrete damp but not flooded 9. LS9500 dries quickly, so if you need to use multiple sprayer refills just continue where you left off and repeat the application technique 10. If some of the sealer starts to dry on the edges between refills it will be sealed, so minimize over-wetting these areas to reduce build up 11. The treated surface will look darker while drying, and lighten as LS9500 cures over the next several hours The results were impressive. The appearance of aggregate, with a natural clear finish, made the driveway look much younger than it's age. Now that it is water proof, surface water dries quickly and it resists staining and mold much better than before. It was a good investment of my time and money, and it was an easy DYI project to accomplish. I hope this overview of my experience was helpful.

Parfait pour protection de notre plache de garage. En concentré facile a diluer. Facile d'utilisation

It was the cheapest highly rated sealer so I bought it. It went on easily with a garden sprayer. The water beaded up after the first application, however the instructions say that you should do two applications. I will do a second application in the spring when we have temperatures above 50.

Appears to be a good choice after one month. Applied 2 wet coats to 700 squares of old unsealed pool deck. Pre-cleaned using the Chlorox concrete cleaning method. Caveat : The finished surface has a slight grease texture which is probably a siloxane component.This did not alter the non slip surface and causes the water to bead (consumer preference)

The concentrate mixed easily with water and sprayed well using my pressure sprayer. It covered and appeared to penetrate my basement walls and particularly around the bulkhead. I followed the directions and applied two coats in close succession. It looks good and will hopefully do the job of stopping water seepage into my cellar!
