Contact layers on smooth, non-absorbent substrates
As an alternative to priming, it is also possible to create contact layers produced from cement-based and highly polymer-modified materials. This method is particularly suitable when pre-treating smooth, non-absorbent substrates in exterior areas, such as old tiles on balconies and terraces. Smooth concrete surfaces are also ideal to be prepared in this way. BOTAMENT MD 1 Speed Flexible sealing slurry is excellent for this purpose and application is simple.
