Laminated Edge Details
Sub-tops need to be made from 5/8" standard CDX plywood.
The sub-tops edges should be held back 3/8" from the face of
the cabinet to allow the stone lamination to overlap the cabinet
Laminated Skirt Edge Detail
Depth of lamination may vary. Special design features will be
When a stone counter overhangs a cabinet distance of 8" or greater, proper reinforcement is necessary.
We recommend that a 3/8" thick by 3" steel flat bar be routed into the sub
-top surface. These reinforcements should be placed no more than 30" apart and should extend from the cabinet to the edge of the sub-top.
The laminated edge for an overhang counter will be a minimum
of 3" in width to assure added counter strength.
Single Edge Details
Use plywood sub-top if wood trim will cover the exposed sub-top edge.
Sub-tops can be inset into cabinet box if no wood edge trim is desired.
If a sub-top will not be used, reinforcements must be made for sink and range top installation.
COOK TOPS AND RANGES
All appliances that have direct interaction with stone countertops
must be on site with data sheets available to your field representative.
Locations for cook tops or slide-in ranges need to be clearly marked
and appropriate cutouts should be completed.
Downdraft ventilation systems have a very tight tolerance. Careful
preparation is vital for proper fit and installation of stone counters.
Finish all framing and surface preparation prior to the field
The tub should be on site, accurate information regarding cutout
and rim coverage should be available.
It is best to install the tub after the stone is installed.
Access doors for plumbing need to be located and marked.
Faucets mounted through stone must be on site with holes located
and centerlines marked.
All outlets passing through stone should be cut in with boxes
mounted and secured.
All upper cabinets need to be mounted in place.
Range Hoods and under cabinets lights should be mounted for field measuring.
4" or 6" Backsplash
Make sure outlets are installed at correct height, allowing at
least 1" above top of backsplash.
SINKS AND FAUCETS
All sinks, faucets, soap dispensers, instant hots, data sheets and
templates must be on site and available.
The centerlines for each item should be clearly marked with appropriate holes cut into sub-tops.
Holes in sub-tops (for faucets, etc.) need to be oversized so your
plumber can secure all fixtures directly to the stone surface.
The sub-top should be "routed out" if the "lip" of the sink is
more than 1/8". Typically this is necessary with cast iron sinks
and may not be necessary with stainless steel sinks.
The routed area should be 1/4" larger on all sides of the sink
rim to allow for adjustment at time of installation.
Richardson & Latham follow Sink Template guidelines
provided by the Manufacture.
All fireboxes must be in place and mounted prior to field measure.
Screens and glass doors should be on site, unless they are custom made to the opening.
Surface must be prepared for raised hearth applications (i.e. brick, framing, plywood or wonderboard).
Outer surroundings (wood, cast concrete, etc.) should be on site
for accurate measurement.
Full Wall Fireplace
Walls substrate should be either CMU, motar or cement board.
The wall framing needs to be reinforced to withstand the stone
weight. Natural stone weighs approximately 10 to 15 pounds
per square foot for 3/4" slab, depending on type of stone.
