ISOMAT BLOCK-PRIMER - High-Penetration Acrylic Primer

PRODUCT DESCRIPTION

ISOMAT Block-Primer is a premium, water-based acrylic primer engineered for deep penetration and superior stabilization of porous and absorbent substrates. Formulated with ultra-fine particle technology, it anchors deeply into masonry, plaster, concrete, and drywall to bind loose particles and equalize surface absorbency. By creating a uniform foundation, it improves the adhesion, coverage, and finish of subsequent water-based topcoats, preventing uneven drying, suction spots, and flashing.

PRODUCT DETAILS

• High-penetration formula binds loose particles and stabilizes dusty or crumbling substrates

• Equalizes absorption across porous surfaces to ensure uniform topcoat coverage and colour

• Enhances topcoat adhesion to prevent peeling, flaking, and premature coating failure

• Eco-friendly, low-VOC, water-based composition with low odour for interior and exterior use

• Ideal for preparing new plaster, fair-faced concrete, brickwork, render, and drywall
