MaxiPanel® & MaxiPlank® Cement Fiber Siding

Storage
Stack flat on a level surface and keep dry prior to installation. If the materials become wet, in order to prevent shrinkage, allow to dry completely before installing.
|
Painting
Water-based acrylic paint adheres extremely well to MaxiPlank and MaxiPanel. Use high quality exterior grade paints. Two coats are sufficient for long lasting beauty. Do not use oil or alkyd oil based paints or stains.
Always follow paint manufacturer's specifications.
|
Cutting
Straight Cuts:
The Maxiscorer fiber-cement scoring tool is specially designed for easy cutting of planks and panels.
Using a straight edge as a guide, carefully draw the scorer several times toward yourself, applying even pressure on the scorer. Always score the face of the panel. Then, holding the straight edge firmly along the scoring line, bend upwards and break. If necessary, clean the edge with a rasp or coarse sandpaper. If using a power saw, wear mask and goggles for protection.
|
Round Openings:
Circular openings can be made by drilling several holes around the circumference of the desired opening and tapping out the center piece.
|
MAXIPLANK®
Framing
MaxiPlank can be installed to wood or metal framing.
Framing should be in accordance with local building codes. If required by code, a vapor barrier must be installed.
Studs should be spaced at 16 or 24-inch centers. A minimum of a 1 1/2" stud face is preferred to provide sufficient area for fasteners.
|
Fastening
Nails or screws may be used for installing MaxiPlank, depending on type of stud. Nailing guns can be used. No stapling is allowed.
If fasteners are placed less than 1-inch from top or bottom edge at corners of plank, fastener holes should be pre-drilled.
|
Wood Studs:
Use 6d galvanized common nails through both over- and underlapping planks, no closer than 3/4" from bottom edge.
|
Metal Studs:
For light gauge steel frames, use R.P.I. C-Drill 8 x 1 5/8" self-drilling and self-embedding screws. Fasten planks at each stud through both over- and underlapping plank, no closer than 3/4" from bottom edge.
|
Concealed Fastening:
For wood studs, use #11 gauge, 1 3/4" galvanized roofing nails through top of underlapping plank, only, 1-inch down.
With metal studs, use R.P.I. C-Wing 8 x 1 1/4" self-drilling and self-embedding screws through top of underlapping plank, only, 1-inch down from top edge.
|
Installation On Stud or Off Stud:
Fasten flashings at all corners. Provide all undersill, head and side flashings at openings and elsewhere, as required by good construction practices. Fasten metal or wood stops at all corners.
Install a continuous 1/4 inch thick shim strip along the bottom of the frame. This is done in order to kick out the bottom edge of the first MaxiPlank course.
Using a level, snap a chalk line around the perimeter of the framing, at the top edge of first course of MaxiPlank. Install a series of nails or screws along the chalk line, creating a stop or guide for easy installation of the starter course.
|
Install the first plank, starting at an external corner. Make sure that the end of the first plank butts to the corner stop and that the top edge of the plank is against the line of fasteners at the chalk line mark. Fasten the plank at each stud through the shim strip.
Install the next plank in position, aligning edges carefully and butting end of the plank in center of metal jointer. For the first course of planks only, cut off the two lower back leveling lugs of the jointers with tin snips to prevent interference with the shim strip. Slide jointer over the end of the first plank.
To protect against the movement of frame leave a small gap between planks around the building, finishing plank ends flush with all stops. Remove guide nails or screws from chalk line. Start the second course, working from an external corner and using a less than full-length plank so joints are staggered a minimum of two feet.
When joining on stud, use lap gauge or snap chalk line. Plank overlaps can be varied to suit the particular height of the wall. The minimum acceptable overlap is 1 1/4-inch. When butting on stud, fasteners must be installed minimum 1" up from bottom edge, and minimum 3/8" from butt edge.
When installing off stud, use the concealed off stud jointer. Plank overlaps cannot be varied.
|
Continue installing planks around the building. When using concealed jointing, the lower back lugs of the jointer should be placed firmly offer the previous run of planks.
Use same installation method for all runs. For corner details, see drawing under Maxipanel installation.

MAXIPANEL®
|
Framing
MaxiPanels are installed vertically to wood or metal framing. Panels are joined on stud. Framing should be in accordance with local building codes and accepted building practices. If required by code, a vapor barrier must be installed.
Studs should be spaced at 16 or 24 inch centers. A minimum of a 1 1/2 inch stud face is recommended to provide sufficient area for fasteners. MaxiPanel can be used for panel shear walls with bracing meeting local building code requirements.
|
Fastening
Nails or screws may be used for installing MaxiPanel, depending on type of stud. Stapling not allowed.
Wood Studs at 16 or 24 inch Centers:
Use 4d 1 1/2" galvanized box nails at 6 inch centers for shear walls, otherwise at 8 inch centers. Nails should penetrate a minimum of 1 inch into the wood stud. Nails may be drive flush. Use 6d common galvanized nails when installing over additional substrate such as plywood or drywall.
Metal Studs:
For light gauge steel frames, use R.P.I. C-Drill 8 x 1-1/4" or R.P.I. C-Wing 8 x 1-1/4" self-drilling and self-embedding screws. Longer screws should be used when panels are installed over plywood and/or drywall.
|
Installation
Fasten flashings at all corners. Provide all undersill, head and side flashings at openings and elsewhere, as required by good construction practices. Fasten all necessary metal or wood stops at all corners and openings. Install panel with fasteners at 8 inch centers around perimeter and into center studs (6 inches on center for shear walls), minimum 2 inches from corners and 3/8 inches from panel edge. Hold panels firmly against stud when fastening. Leave 1/16" gap between panels and 1/8" between trims. If walls are finished with a modified stucco system, allow 1/8" between panels and 1/4" at corners. Apply modified stucco according to manufacturer's specifications.
Wood Framing:
Fasten panels to studs and top and bottom plates with 4d 1-1/2" galvanized nails. Nails may be driven flush with panel face.
Metal Framing:
MaxiPanel can be installed to metal frames and furring channels. Metal frames should be light gauge sheet metal.
R.P.I. C-Drill and C-Wing screws are designed to self-drill and self-embed the head, just under the panel surface so that holes can be filled and sanded flush.
|
Jointing Methods
Where insufficient stud face is available for nails or screws, pack out to provide additional fastener area.
|
MAXISOFFIT
Fasteners and accessories recommended for MaxiPanel are also used for installation of soffits, porches and carports. Nail or screw all panel edges at 8" centers, and 12" centers in the body of panels, a minimum of 2" from panel corners and 3/8" from edges.
