PlasterBond

Rewettable Bonding Agent

PlasterBond is a rewettable PVA latex bonding agent designed especially for interior/exterior bonding of fresh plaster in patching, plastering and topping applications. Recommended for interior and/or exterior use not subjected to constant moisture, hydrostatic pressure or continuous water saturation.

High viscosity for optimum performance
Minimizes cracks in interior, stucco and plaster when used as an admixture
VOC compliant. VOC content: < 50 g/l
Blue tint for visual inspection (also available in white)
Improves the flexural strength, bond strength and impact resistance of plaster, and stucco mortars to concrete

Application

Surface Preparation

The existing substrate must be mechanically abraded to remove all unsound concrete, ensuring it is structurally sound and free from contaminants such as laitance, grease, oil, or dirt for optimal bonding.

Mixing and Application Guidelines

Mixing: Agitate well before use.
Application: Apply a uniform coating of undiluted PlasterBond at a rate of 250 sq-ft per gallon using a brush, roller, or sprayer. Ensure it forms a continuous film over the area to be bonded. The treated surface should remain slightly tacky when dry.
Drying Time: Typically 20-30 minutes at 70°F, though this may vary with ventilation.
Reapplication: Porous surfaces may require a second coat after 1-2 hours if a continuous film is not achieved.

Application Rate and Conditions

Apply PlasterBond up to 24 hours before installing plaster or stucco toppings. Traffic on treated areas should be minimized until the topping is applied.

Packaging

Available in 55 gallon drums, 5 gallon pails, and 1 gallon jugs (sold in cases of four).

Shelf Life

Store in a cool, dry place. When stored properly in its original tightly closed container, PlasterBond has a shelf life of 1 year. Protect from freezing.
