Where to use:

Available in both Type O or Type N formulations and can be used anywhere these types are specified.

How to apply:

Use approved ASTM E2260 pointing technologies. Additional Information

Performance Characteristics

  • Developed for historic structures but can be used anywhere a Type O or Type N mortar is required.
  • Suitable for joint replacement on stone, brick, book tile, terracotta, and cast stone.
Low Shrinkage
  • Maintains integrity of repair, resists cracking.
Breathability
  • Will not cause damage to structure by restricting moisture vapor flow.
Single Component
  • Easy to batch in less than full pallet quantities.
Very low permeability
  • Resistant to deicing salts, chloride, chemical attack, and environmental pollution.
  • Available VE (Viscosity Enhanced) formulas to allow for pumping, bag install or when greater workability, extended working times are desired.

Description

  • RePoint is a Portland/Lime based mortar without the additives often found in masonry cement-based mortars. RePoint does not contain any polymers; it is a proprietary blend of Portland, lime, and sand.
  • Custom color-matching available.
  • 11 standard Masonry Restoration colors.

Preparation

  • Remove all loose and/or deteriorated material as well as any surface contaminants such as oil, paint, grease, etc.
  • Saturate substrate with clean water (saturated surface dry/SSD), with no standing water prior to Application to achieve proper curing.

Mixing

  • Empty contents of the bag or pail into an appropriate mixing vessel.
  • Add 4 to 5 parts powder to 1 part water depending on joint size and shape to achieve proper consistency.
  • Allow to prehydrate for 30 minutes to minimize shrinkage if required by specification.
  • Add additional water (half pint) to achieve desired consistency.
  • Do not retemper after desired consistency has been achieved.

Application

  • Apply using approved pointing technologies (see ASTM E2260) and finish with appropriate tooling.
  • RePoint VE is designed to be installed using a grout bag, mortar pump, or grouting sponge where applicable. Contact your Conproco rep for details.
  • Temperatures should be between 40° and 90°F.
  • Protect from rain and excessive moisture for 12 hours after installation.
  • Protect from below-freezing temperatures for 48 hours after installation.

Clean Up

  • When dry enough not to smear – cut mortar “tags” from the surface and then brush across joints with a dry, soft bristle brush. If a rougher texture is required a stiffer bristle brush can be used.
  • Cleaning with water and chemicals can be performed 3 days after curing. Test cleaning methods prior to beginning to ensure they will not adversely alter the color or texture of the joints.
  • Harsh acids may damage the integrity of the mortar if overused or not fully neutralized. Chemical manufacturers should be consulted prior to testing cleaning methods.
  • Clean tools and equipment with water immediately after use.
  • Cured material must be removed mechanically.

Curing

  • Mist the substrate after initial set (24 hours) to ensure hydration and minimize shrinkage cracking.

SPRAY AND PUMPING EQUIPMENT

CEMENT BASED MATERIALS

The gallons per minute volume of a rotor/stator pump is determined by the pump size. The pressure capacity of a pump is determined by the number of stages. Thicker materials and longer distances require higher pressure.

Manufacturer Web Addresses

LIQUIDS AND COATINGS

The capacity of airless spray equipment is determined by the tip size. Given the proper tip size, the manufacturer of the equipment will be able to recommend specific equipment.

Color-matching repointing mortars by adding color in the field can produce shades of color that vary from batch to batch.  Factory blended mortars are more consistent but often require a higher minimum quantity than a project requires. Repoint can solve both issues. Repoint is a color matched repointing mortar (Type N & Type O) available in quantities from a single 50 lbs pail to unlimited skids in 50 lbs bags.

Both Repoint and Repoint VE meet the requirements of ASTM C387 and C270.

Projects Showcase

Nevins Manor

Project History

The Henry C. Nevins Home for the Aged and Incurables was commissioned in 1906 by Henry as a memorial to his father, local industrialist and philanthropist David C. Nevins, Sr. The building was added to the National Register of Historic Places in 1984. Traditional Portland cement, lime and sand mortar is very labor intensive for contractors to produce in the field. The project team preferred using an appropriate manufactured Type N mortar to ensure quality control and color consistency. Conproco’s RePoint is a traditional mix that only requires the addition of water at the job site. It contains no polymers, additives or masonry cement.

 

1608 Chestnut Street

Project History

1608 Chestnut Street is part of the National Register Center City West Commercial Historic District, and was added to the Philadelphia Register of Historic Places in 1985. The 3 story limestone building still features all of its original architectural details. As part of the conversion to Uniqlo, Mara Restoration cleaned and repointed the façade. Conproco’s RePoint was chosen as the repointing mortar. RePoint is a traditional Portland, lime and sand mix. It contains no polymers or additives, and comes packaged as a just-add-water mix.
