PHYSICAL PROPERTIES

Application Instructions:

SURFACE PREPARATION:

Solid, clean surfaces are required for the effective application of OCTOPLUG PLUS.  Chip or chisel away all loose or defective material from areas to be repaired.  Provide sound mechanical key by undercutting (preferred) or square cutting (acceptable), an opening for the entire length of the hole, crack or joint to be sealed.  Prepared patch area should be minimum ½ inch wide and ½ inch deep (12.7 mm x 12.7 mm) (DO NOT V CUT).  Remove any dirt, dust, oils grease or loose debris and wipe or brush clean.  Area should be dampened before and after packing in OCTOPLUG PLUS.

MIXING:

For all applications (except re-surfacing) mix only as much material at one time as can be placed in 60 to 90 seconds.  Dampen the mixing container, add 60 to 90 seconds supply of OCTOPLUG PLUS powder to sufficient clean, cool water while vigorously kneading to bring to a stiff putty-like consistency.  Always add powder to water.  For re-surfacing with sand addition, premix the dry sand and dry OCTOPLUG PLUS powder and proceed as above.  Bring wetted material to a slurry consistency.

PLACEMENT:

To stop running water, start at the top or end of the prepared opening and force OCTOPLUG PLUS mortar firmly into the opening with a packing action, but with a minimum working of the surface.  Where water is flowing under pressure and likely to force the material out of the opening, hold the putty-like OCTOPLUG PLUS in the palm of the hand until the mix feels warm.  Then immediately force the warm OCTOPLUG PLUS into the opening and keep pressure on the plug with the heel of the hand or trowel until the material hardens and water stops flowing.  After setting occurs, the surface may be scraped for leveling.

Where water pressure is not present, no sag, putty like OCTOPLUG PLUS is firmly forced into the opening for a complete fill.

In anchoring applications, place the mix in the opening and force the metal fixture in at the center of the plugged opening.  Tamp firmly around the surface and keep the mortar surface moist for 15 minutes.  The imbedded fixture may be safely utilized after 10 hours.

For re-surfacing, place with a gloved hand as a float.  Level while rubbing.  For smoother final surface the patch can be re-dampened immediately after its initial set and the surface worked with a clean steel trowel or similar hard, smooth tool.

Limitations:

Setting time is accelerated by heat and decreased by cold.  The 60 second initial set occurs when the water and surface temperature are at 70°F (21°C).  Mixing water must never exceed 100°F (37.8°C).  If the surface is hot to the touch, very cold water for mixing will counter-act surface heat.  It is advisable to have the OCTOPLUG PLUS powder at room temperature prior to mixing.  Do not mix more than can be used in 60 to 90 seconds.  Do not use at temperatures below 40°F (4.4°C).

CAUTION – FOR INDUSTRIAL USE ONLY:

Wet cement, especially as an ingredient of a plastic mixture, can dry the skin and cause alkali burns.  Cement dust can irritate the eyes and respiratory system.  Cement dust can cause inflammation of the lining tissue of the nose and inflammation of the cornea.  Hypersensitive individuals may develop an allergic dermatitis.  Cement may contain traces of hexavalent chromium.

This product may contain 2 to 50 percent silica sand, a portion of which may be respirable dust.  In its dry state, refrain from inhalation of dust to prevent possible free silica exposure.

Users should wear rubber gloves, eye protection and protective clothing to prevent skin and eye contact.  Good ventilation to control dust levels is recommended.

Before use, contact manufacturer to obtain Material Safety Data Sheet (MSDS) and consult package label for additional safety and use information.
