Polyguard Products specializes in products that protect surfaces and structures from moisture, water, and other undesired substances. Polyguard is currently operating under three "core" divisions with a number of growing divisions under the Polyguard umbrella.
Polyguard's Architectural Division offers the Integrated Building Envelope System, with air barriers, masonry through wall and window flashings, below grade structural waterproofing systems, and composite drainage panels, all connected using engineered transition detailing assemblies which assure envelope integrity.
Polyguard's Pipeline Division was the first coating manufacturer to highlight the cathodic shielding problem and the first to develop a coating to address the shielding problem. We have introduced a 2-part epoxy coating with 30% - 50% longer pot life than the competition.
Our Mechanical Division offers weather and vapor barrier systems to keep pipe and duct insulation dry, as well as a unique RG-2400 coating to stop corrosion under insulation (CUI).
Polyguard's Specialty Products Division is comprised of products for Highway, Residential, Flooring and Private Label applications.
A new innovation from Polyguard is the TERM Barrier Systems. Backed by 18 years of university research and ICC Evaluation Report #3632, you can optimize building waterproofing by adding non-chemical termite and insect barriers.
In May of 2016, Polyguard introduced a new business unit called Poly Wall Building Solutions - Moisture and Air Stop with Us.
Polyguard's Residential Division manufactures a market-leading line of waterproofing and air barrier membranes designed to enhance the integrity of your structure. Our products are all made in the USA and have been tested to withstand the most rigorous requirements in the construction industry. With 60-plus years of manufacturing excellence and a culture only found in an employee-owned company.
Think of Polyguard as an innovator and manufacturer of barriers - not just barriers against moisture and corrosion, but against contaminants like radioactive radon gas and methane. No sick buildings here.

INSTALLATION (650)
Install in accordance with manufacturer's instructions, approved submittals, and in proper relationship with adjacent construction.
Priming:
Apply primer by roller or spray to a cleaned, dust free surface to provide a tacky adhesive surface. Tack or cure for these primer products is totally dependent on relative humidity, ambient temperature, and substrate surface temperature. Apply Polyguard 650 LT Liquid Adhesive or Polyguard California Sealant at a rate of 250 to 300 sq ft (23.22 to 27.87 sq m) per gallon or Polyguard 650 WB Liquid Adhesive at a rate of 350 to 400 sq ft (32.52 to 37.16 sq m) per gallon. Allow to dry per manufacturer's directions. Do not prime underneath Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane.
Membrane Installation on Vertical Surfaces:
All inside and outside corners are to be treated with a 12 inch (305 mm) wide strip of Detail Tape centered along the vertical axis, or by applying a 90 mil (2.29 mm) thick application of Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane.
Install a 3/4 inch (19 mm), 45-degree angle cant (fillet) of Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane at all changes in plane including inside corners to 6 inch (152 mm) vertically and horizontally beyond the cant (fillet). Do not use wood or fiber cant strips.
Waterproofing membrane should be applied vertically in sections of 8 ft (2438 mm) in length or less. When vertical walls sections of more than 8 ft (2438 mm) are to be waterproofed, apply 650 Membrane in sections no longer than 8 ft (2438 mm), starting from the lower foundation base and rising to the top with the 6 inches (152 mm) overlap, shingling down on each ply of membrane.
Side laps should be 2-1/2 inches (64 mm) minimum and staggered end laps should be 6 inches (152 mm) minimum.
Use a hard roller or firmly press in the material as it is placed on the vertical surface.
At penetrations, posts, or projections, seal with Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane 6 inches (152 mm) onto concrete and 3 inches (76 mm) onto penetrating item; then apply a second flashing sheet over the penetration extending a minimum of 6 inches (152 mm) from the detail. Seal the cut edges of all terminations with Polyguard Detail Sealant PW or Polyguard LM 95 Liquid Membrane.
Pipes which are wired together and touching, cannot properly be waterproofed. Ensure all pipes have proper spacing. Recommended spacing for pipe penetrations is 2 inches (51 mm). The minimum allowed is 1 inch (25 mm).
All terminations of the membrane should receive a troweled bead of Polyguard Detail Sealant PW, LM-95 Liquid Membrane to a flat surface approximately 1/8 inch(3 mm) thick by 3/4 inch (19 mm) wide.
Inadequately lapped seams and damaged areas should be patched with Polyguard Detail Tape. Patched areas should extend at least 6 inches in each direction beyond the defect.
Fish mouths and/or severe wrinkles should be slit, flaps overlapped, and repaired.
Membrane Installation - Horizontal Surfaces:
All inside and outside corners shall be treated either with 12 inch (305 mm) strips of membrane or a 12 inch (305 mm) wide by 90 mil (2.29 mm) thick application of Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane. The field membrane should be centered over the corner. All inside corners shall have a minimum 3/4 inch (19 mm) fillet of Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane or latex modified cement mortar.
Apply waterproofing membrane to the primed surface starting at the low point and working to the high point in a shingling technique for maximum drainage.
Side laps should be 2-1/2 inches (64 mm) minimum and staggered end laps should be 6 inches (152 mm) minimum. Refer to Polyguard slope and/or zero-slope applications for Balconies and proper lap adhesion requirements.
Firmly roll the entire membrane with a minimum 75 lbs (34 kg) linoleum roller immediately after application. This will ensure excellent adhesion and minimize air pockets between the substrate and membrane.
At penetrations, posts, or projections, seal with Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane 6 inches (152 mm) onto concrete and 3 inches (76 mm) onto penetrating item; then apply a second flashing sheet over the penetration extending a minimum of 6 inches (152 mm) from the detail. Seal the cut edges of all terminations with Polyguard Detail Sealant PW or Polyguard LM 95 Liquid Membrane.
At drains, apply Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane around the inside edge of the drain out onto substrate at least 6 inches (152 mm) then overlap with sheet membrane a minimum of 6 inches (152 mm). Seal all permanently exposed cut edge terminations with Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane.
Membrane turned up on walls shall be terminated. Firmly press the terminated edge with a hand roller and protect with a troweled bead of Detail Sealant PW or LM-95 Liquid Membrane.
Inadequately lapped seams and damaged areas should be patched with additional membrane. Extend patch at least 6 inches (152 mm) beyond the defect.
Slit all "fish mouths," overlap the pieces, place patch over area and roll in place. Air blisters are typically caused by exposure and heat; this condition will subside as the sun no longer heats the membrane. This condition does not need attention unless blisters are large or excessive, softball size, and do not dissipate. Puncture large air blisters, expel the air, prime and cover with patch. Extend the patch material at a minimum of 6 inches (152 mm) in all directions beyond the repair area, then seal the patch edges with Detail Sealant PW or LM-95 Liquid Membrane.
Upon completion of horizontal membrane application, Polyguard recommends a flood test or appropriate leak detection method be completed on the surface with 2 inches (51 mm) of water for 24 hours. Check with the structural engineer to make sure the deck structure will withstand the weight of the flood test. Mark any leak areas found during flood test and make repairs.
Protection and Drainage Course:
Apply protection board and/or drainage composite and perimeter drainage composite in accordance with manufacturer's written directions.
** NOTE TO SPECIFIER ** Delete article if not required.
INSTALLATION (PRM)
Install in accordance with manufacturer's instructions, approved submittals, and in proper relationship with adjacent construction.
Priming:
Apply primer by roller or spray to a cleaned, dust free surface to provide a tacky adhesive surface. Tack or cure for these primer products is totally dependent on relative humidity, ambient temperature, and substrate surface temperature. Apply Polyguard 650 LT Liquid Adhesive or Polyguard California Sealant at a rate of 250 to 300 sq ft (23.22 to 27.87 sq m) per gallon or Polyguard 650 WB Liquid Adhesive at a rate of 350 to 400 sq ft (32.52 to 37.16 sq m) per gallon.

All inside and outside corners shall be treated either with 12 inch (305 mm) strips of PRM or a 12 inch (305 mm) wide by 90 mil (2.29 mm) thick application of Polyguard Detail Sealant PW or Polyguard LM-95. The field membrane should be centered over the corner. All inside corners shall have a minimum 3/4 inch (19 mm) fillet of Polyguard Detail Sealant PW or Polyguard LM-95 or latex modified cement mortar.
Apply PRM to the primed surface starting at the low point and working to the high point in a shingling technique for maximum drainage.
Side laps should be 2-1/2 inches (64 mm) minimum and staggered end laps should be 6 inches (152 mm) minimum. Refer to Polyguard slope and/or zero-slope applications for Balconies and proper lap adhesion requirements.
Firmly roll the entire membrane with a minimum 75 lbs (34 kg) linoleum roller immediately after application. This will ensure excellent adhesion and minimize air pockets between the substrate and membrane. Give special attention with the roller to membrane overlaps and ' T-Joints.'
At penetrations, posts, or projections, seal with Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane 4 to 6 inches (102 to 152 mm) onto concrete and 4 to 6 inches (102 to 152 mm) onto penetrating item; then apply a second flashing sheet over the penetration extending a minimum of 6 inches (152 mm) from the detail. Seal the cut edges of all terminations with Polyguard Detail Sealant PW or Polyguard LM 95 Liquid Membrane.
At drains, apply Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane around the inside edge of the drain out onto substrate at least 6 inches (152 mm) then overlap with PRM a minimum of 6 inches (152 mm). Seal all permanently exposed PRM cut edge terminations with Polyguard Detail Sealant PW or Polyguard LM-95 Liquid Membrane.
PRM turned up on walls shall be terminated. Firmly press the terminated edge with a hand roller and protect with a troweled bead of Detail Sealant PW or LM-95 Liquid Membrane.
Inadequately lapped seams and damaged areas should be patched with additional membrane. Extend patch at least 6 inches (152 mm) beyond the defect.
Slit all "fish mouths," overlap the pieces, place patch over area and roll in place. Air blisters are typically caused by exposure and heat; this condition will subside as the sun no longer heats the membrane. This condition does not need attention unless blisters are large or excessive, softball size, and do not dissipate. Puncture large air blisters, expel the air, prime and cover with patch. Extend the patch material at a minimum of 6 inches (152 mm) in all directions beyond the repair area, then seal the patch edges with Detail Sealant PW or LM-95 Liquid Membrane.
Upon completion of horizontal membrane application, Polyguard recommends a flood test or appropriate leak detection method be completed on the surface with 2 inches (51 mm) of water for 24 hours. Check with the structural engineer to make sure the deck structure will withstand the weight of the flood test. Mark any leak areas found during flood test and make repairs.
Protection and Drainage Course:
Protection board is not required but an optional drainage board can be applied over membrane to expedite water dispersion prior to backfilling. Apply drainage composite in accordance with manufacturer's written directions.
