Thermal Insulator 301
Solvent penetrating sealer that consolidates weak substrates.

The product, up close.


The problem it solves.
Weak, dusty, highly porous substrates cannot be painted reliably. Friable surfaces fail under any coating.
A solvent-based deep-penetrating sealer that consolidates and strengthens.
Contractors facing old, chalky or crumbling substrates.
Weak and porous interior and exterior surfaces.
What it is.
A high-performance solvent-based sealer designed to deeply penetrate porous surfaces, strengthen weak substrates, reduce absorbency and improve the adhesion and durability of subsequent coating systems. Suitable for interior and exterior.
Where it performs.
Why specifiers choose it.
Deep penetrating action
Excellent substrate consolidation
Superior adhesion promotion
Reduces surface porosity
Enhances topcoat performance
Excellent alkali resistance
Reduces paint consumption
Fast drying

How it's applied.
Ensure the surface is clean, dry and free of oil, grease and loose particles.
Apply one uniform coat by brush, roller or spray.
For highly porous surfaces, apply a second coat after the first dries.
Allow sufficient drying before subsequent coats.
