MT Substrates Image

Store materials in original packaging at temperautres between 40°F and 120°F (4°C - 49°C).
Protect materials from direct sunlight and inclement weather until ready for use.

Inspect surface, touch-up, sand or scrape to make smooth
Ensure the substrate is clean, dry and free from dust, dirt, and debris
Ensure substrate fasteners are flush with surface and fastened into solid backing.

Do's

Don't's

DO communicate with the general contractor and other trades to avoid careless damage
DO remove ponding water as soon as possible
DO cover membrane as soon as practical, maximum exposure time is 180 days
DO follow recommended installation instructions for optimum product performance
DO roll discarded release liner for optimum disposal efficiency
DO add additional appropriate protection over membrane when welding or grinding

DON'T install surface with ice or frost present
DON’T leave release liner underfoot, dispose immediately
DON’T store materials in direct sunlight and inclement weather until ready for use
DON'T subject SlopeShield Plus to any chemicals
DON'T install SlopeShield Plus SA over standing water
DON'T ball up release liner

Persons who access any roofs, involved with roof construction, repair or maintenance shall use appropriate personal protective equipment including, but not limited to, hard hats, eye protection, and leather gloves and must be trained on safe practices relevant to their work.
Where the use of ladders, scaffolds, platforms, or temporary floors are utilized, safety lines and safety harnesses shall be used. Please access the OSHA Web site at www.osha.gov, contact your local OSHA office, or visit the local federal bookstore to obtain the most current information on OSHA 29 CFR 1926.
Caution: Release liners are slippery. To prevent injury, liner should be removed from under foot as soon as membrane is installed and disposed of properly.


1. Remove temporary factory wrap. Install post/columns.	2. Wrap post/columns with WallShield IT to protect against moisture, mold, and construction damage. Use VaproTape to hold seams together when required, add corner protection (by others).


3A. Measure and cut WallShield IT to fit around the entire beam. Cut tabs on top and secure with staples to ease removal.	3B. Place WallShield IT over the top of the beam and secure temporarily with a few pieces of VaproTape on the sides.


	4. Connect and/or install wrapped post/column to wrapped beam. Use VaproTape as required on seams.

5A. Construct mass timber floor/deck. 5B. Remove top pieces of WallShield IT just before panels are laid.	6A. Prepare the substrate for installation. Inspect the surface, make any necessary touch ups, and fill voids and gaps greater than 7/8" (22.2 mm) wide. 6B. Ensure substrate is clean, dry, and free from dust, dirt, and debris. Use a vacuum or best means to remove dust. 6C. Ensure fasteners are flush with surface and fastened into solid backing.

CAUTION: Release liners are slippery. To prevent injury, liner should be removed from under foot as soon as membrane is installed and disposed of properly. 7A. Install SlopeShield Plus SA over mass timber deck/floor to protect the mass timber from moisture intrusion and construction damage. 7B. Tape all seams/laps using VaproTape. 7C. Broom and roll membrane with (+/-) 100lbs. flooring roller to ensure adhesion. Note: Mass timber panels with factory-applied SlopeShield Plus SA also require VaproTape at all seams and laps when the pitch is less than 2:12.


8A. Protect end grains from damage and facilitate rapid water removal. 8B. Using a roll of 19" SlopeFlashing slit the release film approx. 6" from the top. 8C. Adhere 3" of the flashing over the SlopeShield Plus SA on the deck. Adhere the remaining 3" onto the end grain. Allow the remaining flashing roll, with the release film on the back, to hang down. 8D. Apply VaproTape over the flashing seam. NOTE: Taping over lap edges in field may be omitted where slope is greater than 2:12. 8E. In high wind areas install nailing strip or termination bar for added wind protection

9A. Install the next level of post/columns and beams. 9B. Protect EACH column base using the steps outlined above.

10A. Using a piece of membrane or flashing, cut 4ea. according to pattern and onsite dimensions. 10B. Do NOT remove the release film during the cut process.

11A. Adhere against the post and the side of the posts. 11B. Smooth remaining part of membrane over the floor/deck.	11C. Continue this process around the post.

12A. Apply VaproTape over all seams and edges of SlopeShield Plus SA.	13A. Install WallShield IT over post protection to optimize mass timber protection.
