Pore Sealant


Harmony Pore Sealant is a water-based primer/pore sealant which is recommended for use prior to the application of Harmony Optimum Lacquer.


Type: single component water based primer/pore sealant

Colours: White

Dosage: 1 l = 10 – 12m2 in a single coat

Storage: 12 months in unopened original packaging, stored in a dry and frost-free location.

Guarantee: Manufacturer’s liability

Tools & Cleaning

Lacquer roller, paint gun, sprayer, protective gloves, tarpaulin, paint tray.

Clean tools in water after use.


The base surface must be resistant, sound, solid, clean, dry and free of humidity.

Use Harmony neutral agent or Harmony degreaser for any cleaning required (to remove grease, oil etc).


Application must be completed within a temperature range of 5° - 25°.

Coverage: 1 litre/10 - 12m2.

Apply a thin and uniform film in a ratio of 1 litre per 10 m2, applied in a single coat.Where a lacquer roller is used, apply a crosswise action to ensure the effective spreading of pore sealant. Do not create any excess thickness.

Where a large area is to be covered, use the 250 or 500 mm PermaPro special floor nozzle, or the PermaPro paint gun.

On an anhydrite screed or smoothed concrete, it is recommended to moisten the base slightly with a microfibre mop before applying.

If the existing soil has a high porosity, a second layer must be applied.

Wait 2 to 4 hours before applying Optimum Lacquer. In winter drying time may take longer.

Bon vernis

Anonymous customer published the 13/12/2018 following an order made on 01/12/2018


Nous sommes ravis du résultat c'est exactement ce que nous attendions. Les 2 couches de vernis sont largement suffisantes le rendu est bien mat et super agréable. Merci

Parfait. La fourniture des rouleaux pour appliquer est un vrai plus quand on a une grande surface. le rendu est top. je cherchais un vrai mat et je ne suis pas déçu.

Anonymous customer published the 26/07/2018 following an order made on 27/06/2018


Le bouche-pore assombrit la teinte de la chape de blanc pierre à sable. Kit pour 50m2, la quantité de bouche-pore (5l en 1 seule couche) m'a paru insuffisante (pièce de 46m2). Une 2ème couche aurait à mon sens été nécessaire pour garantir une imperméabilisation homogène de ma chape anhydrite. Je constate encore quelques zones qui marquent à la goutte d'eau. Le vernis fera le reste je suppose.

Comment from Harmony Béton the 27/07/2018
Notre bouche pore n'a pas comme 1er objectif de rendre hydrofuge la dalle mais de réduire la consommation du vernis et favoriser son accroche. Une seule couche suffit dans notre process

Anonymous customer published the 29/05/2018 following an order made on 16/05/2018


, vernis facile à utiliser. A noter: le bouche pore permet de ne pas trop foncer la teinte de la chape!
