  1. Gauged flag stone can be adhered directly to the Silca grate™ we recommend Surebond 190 this can be done as a perimeter glue where the interior stones will remain in place by virtue of weight and friction or each stone can be glued down (Stone must be evenly cut) Natural stone can be installed the same as standard pavers.
  2. We recommend using polymeric sand.
  3. We do not recommend using exterior mortar to fill your joints or adhere Gauged flag stone can be installed in the same manner as natural stone or standard pavers depending on how even the sides are cut.
  4. We do not recommend using exterior mortar to fill your joints or adhere your stones Recommended methods of finishing the outer edge of deck (Rim Joist, Fascia), Wood or Composite decking material can be used, Pavers or natural stone can be used to finish they can be adhered with recommended glue and use of either a temporary or permanent ledger board.

Non gauged flag stone installation is possible with Silca grate™, however in this instance two layers of geotextile fabric and base of bedding sand needs to be used and all sides of the deck need to contain the sand and stone. As you lay each stone down it must be seated in the sand and then and leveled to the stone adjacent to it. Try to keep the joint lines between stoned to a minimum width This process needs to be repeated through the entire installation. The stone will not by its nature be completely level, their will me high and low spots

  1. SilcaGrates™ should be installed with the straps to the top, facing upwards.
  2. Natural stone can be adhered directly to the Silca Grate™. We recommend Surebond 190 or an equivalent.

Natural stone can be installed the same as standard pavers.
  3. Only use polymeric sand when creating joint lines.

You can glue the pavers you used for the deck flooring around the edge, or you can use pressure treated lumber, cedar, or redwood as edging.

When applying stone to steps, SilcaGrates should be installed with the straps up, then adhere the stone to the SilcaGrates using a construction adhesive such as Surebond-190 or equivalent.

Yes. For customized cuts around posts or dryer vents, use a circular saw, table saw, or sawzall. Remember to add blocking under any cut edge of the SilcaGrates.

No. Wood and composite flooring trap water and moisture, creating an environment for mold and mildew. Wood and composite deck boards also warp and distort over a period of time, making an unacceptable surface for proper Silca Grate™ installation.

The dimensions of the Silca Grate is 16″ wide, 18″ long, 1 ½” thick, and weighs approximately 4 lbs.
