SmartKey 99-H is a premium quality pre-packed proprietary cement-based mortar that is specially formulated with additives and polymers for use on various substrates such as concrete to provide a mechanical key coat which further improves the bonding of plaster, render and screeds.
Also known as a spatterdash, SmartKey 99-H has improved bonding strength over conventional on-site mixes of neat cement or cement/sand slurries. It is recommended for use on inherently difficult substrates such as dense and smooth concrete elements or highly absorbent substrates.
