How this coating category should be evaluated.
This representative renovation application focuses on a concrete bonding agent used between a prepared existing mineral substrate and a new repair, render or cementitious layer. Product suitability depends on substrate strength, contamination, moisture, repair thickness, following material and application timing. Meilida can support distributors and contractors with product selection, samples, package sizes and private-label supply.
Application challenge
Old concrete and plaster may contain dust, weak laitance, oil, curing compounds, paint or hollow areas. Applying new material over an unsound or closed surface can lead to poor bond, cracking or delamination even when a bonding product is used.
System approach
Remove weak and incompatible material, mechanically prepare where required, clean the surface and confirm moisture conditions. Apply the bonding agent at the recommended coverage and place the following repair layer within the defined open or tacky window. Trial adhesion should be checked for the actual substrate and repair material.
