MasterShield PRI 155

Water-Based Acrylic Primer Used Before Anti-Carbonation Coating Application (formerly MasterProtect P 155)

How Does MasterShield PRI 155 Work?

MasterShield PRI 155 is a water-based acrylic primer used to prime mineral substrates before applying MasterShield top coats.

MasterShield PRI 155 is recommended for application to cementitious and other mineral substrates to seal the surface and improve adhesion for subsequent MasterShield AC 160 or MasterShield AC 150 coatings. Application of MasterShield PRI 155 also eliminates differences in absorption which can give rise to irregularities in the final finish.

What Are the Benefits of MasterShield PRI 155?

• Versatile - compatible with porous and non-porous substrates

• Vapour permeable - allows the structure to breathe
