Substrate Strengthener & Bonding Age

Substrate Strengthener & Bonding Age

0.0/5 rating (0 votes)

Use and properties

Improves setting conditions of mortars – contributes to reaching their expected parameters.
Strengthens the surface of primed mineral substrates – permeates the surface, strengthens it and strengthens and improves its load capacity. Prevents retention of excessive amount of water from the layer applied upon the substrate – limits the absorption of the substrate.

Unifies the absorption of the whole primed surface – the applied layer has similar setting conditions, irrespective of local changes in the substrate parameters.
Creates temporary protective layers on subfloors and screeds– improves the resistance of the floor to dust deposition, facilitates its cleaning (must not be considered as the final finishing layer).
Increases the yield of paints, finishing coats and adhesives – by sealing the structure of the primed surface, it increases the yield of materials used for the execution of the next layer.


Kinds of primed substrates – absorbent, excessively absorptive and weakened: concrete, plasterboard, gypsum and cement renders, rough walls made of all kinds of bricks, blocks, hollow bricks, as well as concrete and anhydrite subfloors.
Types of finishing layer – tile facing, renders, subfloors, finishing coats, wallpapers, paints (follow paint manufacturer instructions), AVAL KL 51 (ATLAS WODER E), ATLAS WODER W, ATLAS WODER DUO or ATLAS WODER S watertight insulations.


Substrate preparation
The substrate must be dry, free from dust, dirt, oils, grease and wax.
Remove all loose layers inappropriately adherent to the substrate before emulsion application.

Emulsion preparation
It must not be mixed with other materials or thickened. It is admissible to dilute in a proportion by weight of:
− − 1:1 for the first priming (in case of double priming of a very weak substrate),
− − 1:3 in case of priming substrates under ATLAS paints for indoor use.

The best is to apply the emulsion upon the substrate in undiluted form, once, using a roller or a brush, as a thin and uniform layer. For the first priming of very absorptive and weak substrates, emulsion diluted with water in the proportion of 1:1 may be used. After the first layer has dried, repeat the priming using undiluted emulsion this time.

Access to the surface

Painting, wallpapering, tile fixing, etc. may begin after the emulsion has dried, i.e. about 2 hours after its application.

The primer after drying should form matt surface.
