Frequently Asked Questions

The National Block Filler can be applied to unpainted masonry, concrete, cement, and flat-surfaced concrete blocks.

It is recommended to use a sponge paint roller for application, but brushing or spraying is also possible depending on the project.

At 77°F (25°C) and 50% relative humidity, it becomes tack-free in about 1 hour and can be recoated after 2-3 hours. Drying times may be extended by cooler temperatures and high humidity.

The VOC content is approximately 35 grams per litre, complying with environmental regulations and suitable for LEED projects.

The recommended wet film thickness is between 16.0 to 21.4 mils, with a dry film thickness of about 8.2 to 10.9 mils.

It can be tinted with proprietary zero-VOC waterborne colourants for customization.

Ensure the surface is clean, dry, and free of contaminants before application, and avoid applying in temperatures below 50°F (10°C).

Tools should be cleaned with warm, soapy water immediately after use to prevent the product from drying on them.
