  1. Robert B.

    We install wood decks and fences and have been using MSC for 2 years now. Easy to mix and applies with simple garden sprayer. Cleans up with soap and water and we can apply wet on damp so we get the job done in one trip. Customers appreciate that we use a product that will keep their decks and fences protected from water damage and are always happy to hear it is safe and not full of toxic chemicals.

  2. Theo

    Will save you some money if you want a penetrating sealer and are willing to mix before application. Many of our clients ask for recommendations on what they should use to seal decks and patios and SEAL-ONCE is one of the products we are happy to mention. The company is very responsive and you can call their staff daily if you have any questions or issues.
