Pre-1950's Military Buildings - Ft. Ord, CA

Challenge:

The Fort Ord Reuse Authority (FORA) needed to reuse a number of pre-1950’s military buildings which were coated with damaged, lead containing paint. FORA wanted to make these buildings Lead-SAFE without disturbing any dust or removing the loose and peeling paint.

Solution:

To achieve the objectives and specifications listed above, first SE-110 Penetrating-Stabilizer (primer) was applied and brush worked into all the damaged areas. The balance of the surfaces were also coated with SE-110 then brushed and rolled to work the material into cracks and rough areas, sealing and stabilizing these surfaces. SE-110 dries to form a clear, flexible film that remains tacky when dry. Next SE-151 Sealant was applied to weatherize all the window and door openings. Finally, custom-tinted SE-120 Protective-Skin topcoat was applied to all of these surfaces. This work was performed in a manner that did not disturb any lead-containing dust. Any loose flakes that did come off, were re-applied (using SE-110) and placed along the skirt surfaces of these buildings, then over-coated with the SE-120 to produce a Lead-SAFE surface. The client was very pleased with the final result of this encasement work.

Board of Jewish Education Bldg. - NY

Challenge:

The exterior surfaces of this historic building had aging, badly damaged Lead-Based Paint. The owner of the building wanted to restore the appearance of this beautiful building, in an approved and affordable manner.

Solution:

The facade of this building was first wiped to remove dirt and grime, and only the really loose paint was removed. Next, SE-110 Penetrating-Stabilizer (primer) was applied over all the exterior surfaces, sealing and stabilizing the aging paint in a Lead-SAFE manner.  This was followed by application of SE-120 Protective-Skin Topcoat that was custom tinted to meet the client’s needs.

Wells Fargo Bank - Grand Forks, ND

Challenge:

During the course of renovation of the Wells Fargo Bank in Grand Forks, ND and adjoining property owned by the bank, it was discovered that there was mold and mildew on the wooden joists in these old buildings that would lead to ongoing indoor air quality problems if not dealt with in some fashion. The presence of mold and mildew was not a surprise as these buildings were vacant since the Grand Forks flood of 1997. Consideration of available options led to a decision to spray the affected areas with a biocide and then to encase all of those areas. Some of the more minor building components were demolished and replaced, but this was not effective for these weight bearing structural members.

Solution:

The Safe Encasement System, consisting of SE-110 penetrating-stabilizer (primer) and SE-120 protective skin (topcoat) has been tested and found not to support the growth of mold and mildew (ASTM D3273, D-3274). The use of the primer allows for coating over surfaces with little or no surface preparation. The topcoat yields a surface that can be warranted for up to 20 years. This method of dealing with the problem protects against the re-development of mold and mildew problems for many years to come, and yields a washable surface so with some degree of cleaning, future dirt buildups can be removed before mold and mildew growth occurs.

Veterans Home - Minneapolis, MN

Challenge:

Badly deteriorated Lead-Based Paint (LBP) on metal and wood ornate trim at the Minneapolis Veterans Home would have required extensive time and expense to remove by any of the means usually employed for removal, such as scraping or the use of chemical strippers. Removal of the damaged paint also posed a real risk of damage to the ornate surfaces of this historic structure.

Solution:

Only the really loose and flaking paint was removed using approved methods that prevented the release of any Lead-Based Paint into the environment. The wood surfaces were then coated with 16-18 wet mils of SE-110 Penetrating-Stabilizer (primer) and the metal surfaces were coated with 16-18 wet mils of SE-110-CI, Corrosion Inhibiting primer. These materials stabilized the LBP and dried to form a flexible film that remains tacky. After the primers were thoroughly dry, a semi-gloss coating material made by another company was applied over the primed surfaces.

Scottish Rite Cathedral - Minneapolis, MN

Challenge:

This late 1800 era church building located just south of downtown Minneapolis, MN, had its original boilers and associated piping insulated with Asbestos Containing Material (ACM). The insulation was in highly friable condition and their insurance carrier the pursuance of abatement ASAP.

Solution:

The Minneapolis Historical Society recommended the use of a SAFE Encasement System. SE-110 Penetrating-Stabilizer was spray applied directly over both wrapped and unwrapped insulation using care so as not to disturb the ACM. This was left to dry overnight to allow for penetration that renders the old insulation non-friable, then SE-120 topcoat was spray applied, producing a seamless protective barrier that does not adversely impact the insulation value.
