Primer Aquastop Expert 0.5 L concentrate 1:12

Aquastop Expert concentrate 1:12 from Eskaro is a deep-penetrating acrylic primer for high-absorption substrates. One 0.5 L bottle yields 6 litres of ready solution when diluted. Works on gypsum, old plaster, aerated concrete, porous brick - the surfaces where standard primer disappears into the wall without strengthening anything.

Concentrated formula cuts material cost per job: one bottle diluted to task instead of several ready-made ones. Handy for contractors working across multiple flats.

Application is straightforward: mix 1 part concentrate with 12 parts water, apply with a roller or wide brush, let dry to a matte surface. Then hang wallpaper, apply filler or paint. On very absorbent substrates, painters often do two passes - first more diluted, second less so.

For Soviet-era Moldovan flats with limestone-block walls or old crumbling plaster, Aquastop Expert levels absorption and lets the skim coat bond properly.
