Installation11.1 Install protection board wi

15、thin 24 h of completing thewaterproofing membrane installation. Delay installation of theprotection board until the waterproofing film cures. If floodtesting is conducted the application should be as soon aspossible after the surface is dry and clean.11.2 On Low Slope Surfaces:11.2.1 Lay protection

16、board on the membrane in commonbond brick pattern (so that the joints are aligned in onedirection and broken half way over in the other direction) withthe edges butted tightly together. The maximum allowable gapbetween boards is 3 mm (18 in). No area of the membrane shallbe left uncovered. Lay the b

17、oard with the weather coating andbond breaking film away from the membrane.11.2.2 At areas with protrusions and drains, place the boardin the desired position to measure the area to be cut out. Indrain areas mark an area large enough to cover the membraneand the sealed termination. Mark boards as cl

18、ose to theprotrusion as possible while still keeping the board flat.Remove the marked board before cutting (so as not to cut thewaterproofing membrane) using a sharp utility knife. Check thecutout by replacing the board in the original location makingsure it will butt all sheets and adequately prote

19、ct the desiredareas before applying adhesive (if being used) for final placing.Avoid damaging the waterproofing membrane or any flashingsduring application. Boards must lie flat; if necessary, score thebottom of the board to obtain conformance to surface.11.2.3 Cut and fit boards at inside or outsid

20、e angles. Forgentle or “slow” bends, scoring and folding is acceptable. Useadhesive to hold the protection board in position.11.2.4 During windy conditions, weigh the individualboards down, even if adhesive is used.11.3 On Vertical and Steeply Sloped Surfaces:11.3.1 The protection board is to be app

21、lied with the longaxis of the board going up the slope. The joints in thecross-the-slope direction shall be aligned while the up-slopejoints shall be in a stacked brick pattern, with joints centeredover previously applied boards.11.3.2 Using adhesive as described in 7.2, coat the outside100 mm (4 in

22、.) of the board as well as diagonally from eachcorner to make an “X” across the center of the surface of eachprotection board to be installed against the waterproofingmembrane. Full adhesive coating of the board is also accept-able when approved by the manufacturers or suppliers of themembrane compo

23、nents.11.3.3 Immediately place the protection board into positionand roll to secure into position. Follow the same procedurewith all other boards. Apply in common bond brick coursepattern, as described in 11.2.1. Butt the boards against eachother to completely protect the waterproofing surface. As w

24、ithlow slope installations, the maximum gap between boards shallbe3mm(18 in.).11.3.4 At penetrations, place the board in the desiredposition to locate the areas to be cut. Remove the board toavoid damaging the waterproofing membrane and cut outmarked areas with a sharp utility knife. Replace the boa

25、rdcarefully in its original location.11.3.5 At sharp inside or outside angles, cut and fit theprotection board as specified in 11.2.3.11.3.6 For gentle or “slow” corners, scoring and folding isused. Use adhesive to hold the protection board in position.11.4 Seal butt joints of the protection board w

26、ith a suitablemastic or tape. Remove the bond breaking film in the area ofany joint to be sealed.11.5 Inspection and RepairInspect protection board ap-plications to determine that no areas of the waterproofingmembrane are left unprotected. Any unprotected areas shall beimmediately covered before any
