Repoint

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.

• 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.
