    My name is Chris Thorne and I wrote my first Testimonial on Guard Industry product over 2 years ago, I would like to update my Testimonial and let you know I am still using Guard Industry’s cleaning and sealing range.
    As an Accredited Sealer Applicator my go to sealers are Guard Industry’s ProtectGuard® or ProtectGuard® HD Sealers as they are a water base penetrating sealer, 100% Biodegradable, has a 10-year effectiveness guarantee and very user friendly.
    There are no hidden secrets in the “how to use” instructions, for large jobs I prefer to apply the ProtectGuard® Sealer using a sprayer and wiping of the access using a lamb’s wool applicator. Smaller jobs I use a fence paint brush or a lamb’s wool applicator to apply the sealer and use a microfibre cloth to wipe of the access.
    Please remember the key to a good sealing job is preparation and for this I use Guard Wash® or Guard Wash® Express as it eliminates organic contaminates on all materials.
