PIM+ Application Manual

Permanent Internal Membrane Plus - A penetrating concrete treatment for waterproofing and strengthening concrete structures

PIM+ penetrates up to 2mm into concrete, creating a permanent internal barrier against water infiltration while strengthening the concrete matrix.

Step 1: Surface preparation

  • PIM+ can be applied to concrete as soon as you can walk on it without leaving marks (usually 24 hours after placement).
  • Ensure the surface is clean and free from debris.

Step 2: Applying PIM+

  • Use a hand-pump, Hudson can type sprayer for even, soaking, application.
  • Spray back and forth over the same area a minimum 4 times, overlapping as you move up to the adjoining dry area.
  • For vertical surfaces, apply from the bottom up.
  • For horizontal surfaces, apply from the low point (i.e. near a drain) up to the high point.
  • Apply until the surface stays wet for 5 to 10 seconds.
  • Spread any puddles remaining after 30 seconds with a mop or squeegee.

Step 3: Post-application Rinse

  • Any excess PIM+ not spread out before it dries will form a 200 mesh silicate flour (talcum powder consistency).
  • It's recommended to hose off the surface before it air dries.
  • This rinse won't affect the treatment as the gels form inside the concrete within 15-20 seconds.

Step 4: Coverage

  • Coverage varies with concrete porosity - exposed aggregate requires more product than troweled floors.
  • Typical coverage: 100-250 square feet per gallon (average 150 sq ft/gallon).

Step 5: Curing Time

  • The gels formed within the 2mm penetration depth need 72 hours to fully cure.
  • During curing, the gels transform into non-soluble silicate/glass crystals.
  • The treated surface can be exposed to rain or foot traffic while wet without harm.

Environmental and Safety Concerns

  • PIM+ contains zero VOCs - safe for environment, animals, and plants.
  • While safety goggles aren't required, rubber gloves are recommended to prevent skin irritation.

Clean up

  • Clean up hands and tools with soap and water.
