Use this CSI 3 part SimpleSpecs™ master specification to specify clear water repellants for use on concrete and masonry surfaces.
Water repellents are intended to reduce water absorption, deicing salt damage, and freeze/thaw damage on concrete and masonry surfaces. They are penetrating and are available clear and colored and in multiple strengths to suit project conditions.
In general water repellents are short-term solutions. They weather quickly when exposed to ultraviolet and must be reapplied on a regular basis. Since most of them have little or no effect on the appearance of the concrete or masonry, building owners tend to not know when to reapply them.
Water repellents must be highly breathable to prevent trapping moisture in the substrate. Entrapped moisture can freeze, thereby causing spalling. It can also cause a phenomenon known as subflorescence, in which salts brought towards the surface by water in the concrete or masonry get trapped under non-breathing coatings, exerting internal pressures that can result in severe spalling.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
