15、oofing membrane must be clean and suf-ficiently dry so as not to interfere with adhesion of theprotection board.10.2 If a flood test of the membrane is desired, this testshould be made before placing the protection course, inaccordance with Guide D5957.11. Installation11.1 Install protection board w
16、ithin 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
17、 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 membraneshall be left uncovered. Lay the bo
18、ard with the weather coatingand bond 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 clo
19、se 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 protec
20、t 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 outside
21、 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 appl
22、ied 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.

Full adhesive coating of the board is also accept-able when approved by the manufacturers or suppliers of themembrane componen

Apply in common bond brick coursepattern, as described in 11.2.1. Butt the boards against eachother to completely protect the waterproofing surface. As with
25、low slope installations, the maximum gap between boards shallbe3mm18 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 boardcare
26、fully 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 with a
27、suitablemastic or tape. Remove the bond breaking film in the area ofany joint to be sealed.11.5 Inspection and RepairInspect protection board appli-cations to determine that no areas of the waterproofing mem-brane are left unprotected. Any unprotected areas shall beimmediately covered before any bac
