Rainbow Patch is a top of the range acrylic patching compound, which cures to an excellent finish that retains some flexibility, has a high adhesion and excellent durability. Rainbow Patch is perfect for skim coating and patching joints in cement / blueboard sheeting applications. When used as a low build base coat, Rainbow Patch displays levels of adhesion and flexibility not found in conventional cementitious renders. Due to its inherent flexibility Rainbow Patch can absorb minor shrinkage of the substrate, thus reducing surface cracking.
