RQP - Rock Quick Patch

RQP-Rock Quick Patch is a 100% solids, non-shrinking repair paste. This product can be applied using a 300 ml x 300 ml caulk gun in the RQP-TS tube set, or can be used by applying with a taping knife from the 32 ounce or 2 gallon kit set.

Some Product Highlights to Note:

  • Non-Shrinking formula, so cracks and repairs once filled stay filled. This is great for “sinkers” that occur when using traditional 100% solids epoxy.
  • Can be feathered to zero, so no additional grinding is required.
  • 15 minutes of working time, and will usually be fully cured within 45-60 minutes.
  • Has a very high “hardness” rating (Shore D-85).

ROCK-MENDER

Rock-Mender is a 100% solids “ultra-fast” curing polyurea. Like the RQP featured above, this product is easily placed using a 300 ml x 300 ml dual component caulk gun or can be conventionally mixed and placed out of our 2 or 10 gallon sets.

Some Product Highlights to Note:

  • Very low viscosity allows a tenacious bond to sides of concrete repairs virtually welding the slab back together.
  • When used with silica or quartz sand makes a high compressive strength Polymer Concrete.
  • Can be field tinted using select ROCK-TRED Universal Colorants and then polished when fully cured (add concrete dust from your vacuum at the time of mix) to make almost perfectly matched patches and crack repairs.
  • Very fast curing time...one to two minutes

Technical Tips

What does 100% Solids Actually Mean?

The term 100% Solids relates to the volume solids calculation. In the most basic explanation, paints/coatings contain solids and a vehicle. The vehicle has traditionally been a blend of resin and solvents or co-solvents. The vehicle is the solution which helps the wet film to be placed and cure properly or as designed. When a paint or coating is applied it is measured in WFT (wet film thickness). A dried paint or coating is measured in DFT or dry film thickness. If a coating is 90% solids by volume and is placed at 10 mils WFT it will dry to a DFT of 9 mils. This is because it loses 10% of its content to evaporation. If a 100% solids coating is placed at 10 mils WFT it will have a DFT of 10 mils. This is because all of the placed product remains as a part of the cured film. There often is confusion between a paint/coating that has zero VOC’s and one that is 100% solids. This is because certain solvents are designated by the EPA as having negligible photochemical reactivity. As a result a product may be listed as zero VOC but that does not mean it is necessarily 100% solids.
