Ideal for brick facades, concrete areas or stone surfaces
Properties
• Maintains the natural look of concrete surfaces
• Keeps your pavers from crumbling and spalling
• An Ideal sealant for brick, concrete or stone surfaces
• Water-based
Made of siloxanes, WR7 Waterproofing Sealant is specially designed to protect horizontal and vertical concrete surfaces as well as mortar joints. It prevents deterioration caused by de-icing salts and freeze-thaw cycles, while providing resistance to acids and alkalis. Its active agents form an invisible bond that stops the penetration of contaminants, facilitating the maintenance of facades and other surfaces. It helps prevent dust adhesion on the surface, as well as black stains due to air pollution. Water based, WR7 Sealant does not release unpleasant fumes, and it is environmentally friendly

Before you begin
Wait 28 days before applying to fresh concrete or to new mortar joints.
Do not apply to marble, travertine, slate or limestone.
Application to a horizontal surface: Contact Techniseal® for more information: 1 800 465-7325.
Apply only to bare material* or to material previously sealed with this product.
Wait until surface is no longer waterrepellent before recoating (minimum 5 years).
ALWAYS TEST on a small hidden area of approximately 0.4 m2 (4 sq. ft.) to ensure that result meets your expectations (see Warranty).
*ABSORPTION TEST: Sprinkle a few drops of water on surface. If water is absorbed, move on to the next point. If water is repelled, do not apply this product.
Surface preparation (Essential)
1.Cover vegetation, vehicles and adjacent surfaces that are not to be treated.
2.Remove stains with the appropriate Techniseal® stain removers.
3.Clean the entire surface with a cleaner appropriate for the type of surface. Contact Techniseal® to find out what cleaner is best suited for your surface.
Application
Application Conditions :
• Surface must be clean, dry and warm to the touch.
• Temperature must be between 10°C and 30°C.
• No rain forecasted for the next 24 hours.
• Sprinkler system must be turned off.
• Use a consistent application method over entire surface.
Necessary Tools :
• 19 mm foam roller for rough surfaces
• Low-pressure airless sprayer (< 50 psi) or pump sprayer (optional)
Do not dilute. Shake well or stir product before and during application. Product is milky white in its container and will become clear once dry. Avoid product atomization.
Vertical Application : Apply downwards from the top. Using the sprayer or the roller, saturate the surface with a single coat of sealant until the substrate cannot absorb any more product. Surface is saturated when the product runs off 15 to 20 cm below the application point. Avoid accumulation of excess product.
Drying point : Sealant will be dry to the touch within +/- 1 hour. The water-repellent effect will be more perceptible approximately 30 days following application. Surface may appear darker during that period but will regain its original look soon after.
Caution
• Any new concrete product has the potential to produce efflorescence (whitish salts) on its surface. This Protector will not trap efflorescence, which will disappear by itself after prolonged exposure to weathering.
• Do not attempt sprayer application on windy days.
• Do not apply this product over a blotchy or hazed surface.
• In some cases, the treatment could darken the colour of the material.
• Wait 30 days after the installation of polymeric sand before sealing the pavers.
Cleaning & disposal
Wash tools and hands with warm soapy water. Consult your retailer or municipality regarding the disposal of empty containers or unused product.
