How to Seal Concrete
Step 1 Wash Concrete
We recommend using a professional pressure washer (we sell them or you can rent them), with a degreaser (Dawn Dish Soap is one of the best). It is imporatant to have the surface very clean in order to seal concrete.
Step 2 Mix Sealer
This is how we quickly make 2.5 gallons of sealer:
1. Pour 2.25 gallons of plain tap water (9 quarts) into a five gallon plastic bucket.
2. Open concentrated quart-sized bottle of sealer and pour into the bucket.
3. Mix thoroughly (minute or so) with either a drill and a mixing paddle or a large paint stick.
You now have your 2.5 gallons of ready-to-use sealer!
Step 3 Applying the sealer
1. Pour the mixed sealer into a pump-up pressure sprayer and
2. If surface is not dry is a few areas – use a leaf blower to dry. Spray a fine mist onto the surface of the concrete (we use a battery operated pressure sprayer that is attached to a hand cart but any plastic pump-up pressure should work fine).
3. Apply to the point of almost puddling
4. Evenly spread the sealer back and forth with a stiff bristled broom to spread-out any runs.
- You’ll get more square foot coverage on less windy days.
- Product sprays milky white and dries clear in a few minutes.
- Wait 24 hours before vehicle traffic.
- Temps: Good temperature range at time of application – between 50 – 95 degrees Fahrenheit: 50 degrees Fahrenheit on the low end (with no freezing that night) and no warmer than 95 degrees Fahrenheit on the high end.
