Water
repellants and waterproof coatings can be effective in eliminating
water infiltration through brick, concrete, masonry block, wood
and other types of construction materials. Water repellants will
greatly reduce the rate at which these materials absorb moisture.
As a rule, water repellants have little if any crack bridging ability
and will not be as effective on surfaces that have cracks or defective
joints. There are basically two categories of water repellants,
penetrating and surface set. Water repellants are primarily used
in above-grade applications.
Waterproof coatings provide a complete seal over the surfaces to
which they are applied. These coatings are primarily used on non-traffic
surfaces and vertical applications. There are many types of waterproof
coating categories designed for specific applications. There are
acrylic polymer elastomeric coatings, silicone based elastomeric
coatings, cementitious coatings, epoxy coatings, etc. There are
also reinforced and unreinforced systems as well. Almost all of
these coatings are available in a wide range of standard colors
and custom colors can be made if required. Most of these coatings
do have limited crack bridging abilities.
Typical applications for these products would be as follows:
Water Repellants
- Parking Garage Decks
- Balconies
- Exposed Concrete Surfaces (vertical & horizontal)
- Masonry (brick & block)
- Exposed Wooden Construction
- Natural Stone
Waterproof Coatings
- Masonry Walls (brick & block)
- Exposed Concrete Surfaces (vertical)
- Exposed Wooden Construction (vertical)Terracotta
- Exterior Insulated and Finish Systems (EIFS)
Using the wrong type of sealer or coating in the wrong application
can result in poor performance or failure of the product. Things
to consider when selecting a sealer or coating would be:
- Type of Surface to be treated
- Type of surface preparation needed to meet manufacturer’s
requirements
- Expected service life
- Aesthetics
- Application rates
- Compatibility with existing coatings or surface treatments
