Standards


The work done at Picasso Renovations, Inc. Meets or exceeds all of the below standards.

Natural Stone Slab Selection

  1. Basic color, shade variation slabs should be purchased from the same bundle.
  2. Face pitting, fissures, cracks and surface imperfections.
  3. Surface reflection, consistency of polish.
  4. It is recommended that slab thickness be consistent.
  5. It is recommended that slabs be purchased from the same bundle.
  6. All Slabs have mineral characteristics that create a visible texture within the stone and are to be expected in the finished product. Pitting dry veins & fissured can be part of the stone and may affect the integrity of the slab.
  7. Color, shading, veining, & grain direction may affect seams and number of slabs required for project.
  8. The useable square footage of the material.
  9. Check with suppliers on hold policies.
  10. Grain direction should be reviewed before fabrication.
  11. Slab approval form should be reviewed and signed before fabrication.

Field Conditions

  1. Cabinetry is to be installed on a true plane and level to within 1/8" in 8'. Areas to receive stone must be stable and rigid and capable of supporting the weight of the stone. Reinforcement may be required at areas in front of cutouts to insure that they can adequately carry the weight of the stone without flexing. Substrates should be used for stones less that 1" in thickness and should be of a material that is moisture resistant, 5/8" thick is recommended.
  2. If full splash is required, wall mounted cabinets must not interfere with stone installation. Electric outlets must be roughed in according to local code. Appliance garages must not interfere with counter top installations.
  3. Sink, range, dishwasher, etc..., must be available for measurements.
  4. Cabinet doors, drawers, and panels must be installed prior to templating of project. Doors, drawers and end panels are needed so proper overhang can be determined.
  5. Door or window casings must be clear for stone installation.
  6. Edge detail may not always cover subtop due to:
    1. Thickness of stone
    2. Thickness of subtop
    3. Level of subtop

Template Process

  1. Template processes are done in different ways. The fabricator should be contacted with regard to his methods.
  2. It is highly recommended that the Contractor, Homeowner, or an Owner representative be present at time of Templating.
  3. Templated areas cannot be altered after Template process is completed.
  4. Sinks must be at site at time of templating.
  5. Cooktops and downdrafts must be at site prior to installation.
  6. Installation areas should be free & clean with adequate accessibility to install.

Overhangs/Spans

  1. 3/4" Thick Stone counter tops should be installed on an underlayment.
  2. Stone counter tops under 1 1/8" thick should not span more than 2'-0" between support centers. Spans should always be minimized.
  3. Unsupported overhangs shall not exceed 4" on 3/4" thick counter tops. If overhangs or spans exceed maximum amounts, proper brackets, legs or other rigid support must be added by the cabinet maker or builder.

Sinks

There are many different types of sinks and many methods of doing cutouts and installations. The fabricator should be contacted with regard to his method.

Joint Standards

 Width of joint - Joint stone to wall

  1. No splash:
    Stone is to fit to within 1/8" of wall. In a wall to wall or wall to cabinet condition, if wall is out of square, measurement is to be taken at shallowest counter depth. If irregularity in wall surface exists, the edge of the counter top shall be scribed and fitted to wall, or alternately, the wall shall be cut to allow the stone to fit under the edge of the exposed wall face.
  2. Splash:
    Stone is to fit within 3/16" of the wall. If wall is not straight, measurement is to be taken at the shallowest or highest point of wall.

Width and Quality of joint - Stone to stone

  1. Horizontal to Horizontal: maximum of 1/8"
  2. Horizontal to Vertical: maximum of 1/8"
  3. Vertical to Vertical: maximum of 1/8"
  4. On occasion, certain stones may require greater width that A, B, and C. This should be carefully reviewed with the purchaser prior to fabrication.
  5. The abutting stones may be lightly eased when necessary.
  6. Slab joints will be visible and noticeably felt by touch.

Stone to cabinetry:

  1. Horizontal to Horizontal: maximum of 1/8"
  2. Horizontal to Vertical: maximum of 1/8"
  3. Vertical to Vertical: maximum of 1/8"
  4. Distance between subtop and back of lamination approximately 3/8". This distance may vary depending upon the straightness of the subtop and the cabinet.

Quality of joint

  1. The abutting stones may be lightly eased when necessary.

Typical Edge Details

  1. Edge details may vary depending upon thickness of stone.
  2. In some cases, edge color may be different from surface depending on original factory finish.
  3. Any standard or custom edge profile is acceptable. Square edges are susceptible to chipping in a kitchen installation. Where two stones are joined at the edge to increase the thickness, stones must be bonded together.
  4. Laminated seam will be visible if used.
  5. Edge Detail may not always cover subtop due to:
    1. Thickness of stone
    2. Thickness of subtop
    3. Level of subtop.

Installation

  1. Contractor, Homeowner, or Owner representative should be at site to answer any questions that may occur.
  2. Installation areas should be free and clear with adequate accessibility to install.
  3. Setting Materials:
    1. Non-staining bonding agent sufficient to prevent movement shall be used to set stone counter tops and splash pieces.
    2. Jointing material shall be unsanded grout, epoxy, polyester resin and/or siliconized caulk.
  4. Job should be inspected at time of completion by Contractor, Homeowner, or Owner representative. Care should be taken by Contractor, Homeowner, or Owner representitive to protect tops from damage by other trades.

Protection/Maintenance

  1. Counter tops should be protected against damage by Contractor, Homeowner, or Owner representitive immediately upon installation. Counter tops should remain protected against damage until project completion.
  2. All natural stones require sealer periodically.
  3. Maintenace do's and don'ts should be reviewed with fabricator prior to installation.
