Use with Repoint.
How to apply:
Enables bagging. Additional InformationMinimize InformationPerformance 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.
- Maintains integrity of repair, resists cracking.
- Will not cause damage to structure by restricting moisture vapor flow.
- Easy to batch in less than full pallet quantities.
-
- 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.

What makes Repoint unique?
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.
Do Repoint and Repoint VE meet industry standards for repointing mortars?
Both Repoint and Repoint VE meet the requirements of ASTM C387 and C270.
