As a joint filler, the Masterplate 200 surface hardener provides the properties of a metallic aggregate
Master Builders, Inc. joint filler, the MASTERPLATE 200 surface hardener provides the properties of a metallic aggregate in an abrasion and impact-resistant joint solution. The installed material protects joint edges and patches as it prevents spalling in nonmoving control and relief joints in concrete.
The aggregate is controlled to provide uniformity and consistent finishing characteristics. Iron aggregate makes this product a virtually nondusting joint that may be finished from smooth to textured.
