AU-1 Elastomeric Patch Frequently Asked Questions
¿Cuál es la diferencia entre grado para brocha y grado para espátula?
Brush Grade is for hairline cracks — apply it with a clean brush or other flexible blade. Knife Grade should be used for cracks larger than 1/2", applied with a putty knife or trowel.
¿Para qué tipo de grietas y agujeros se utiliza el parche elastomérico AU-1?
Grietas no estructurales más grandes, y reparación e impermeabilización de grietas y agujeros en superficies de mampostería y estuco sobre el nivel del suelo. No está diseñado para grietas estructurales.
How long do I wait between coats or before painting?
If a gap needs two applications, allow 24 hours between them. The product specifications list a 4–6 hour paint-over time, but the application instructions separately say to allow 24 hours before top coating — those two numbers don't fully agree, so it's worth confirming with Tower Sealants which one applies to your situation before painting.
What temperature can AU-1 Elastomeric Patch be applied in?
Apply when sealant, surface, and air temperature are above 40°F and rising, with air no hotter than 95°F and substrate no hotter than 140°F. Don't apply when rain is expected. Once cured, it holds up across a -30°F to 180°F service temperature range.
How flexible is AU-1 Elastomeric Patch once cured?
It offers 300% elongation and stays extremely flexible, which is what lets it move with hairline and larger non-structural cracks instead of re-cracking.
What substrates does AU-1 Elastomeric Patch work on?
Masonry, ceramic tile, wood, concrete, brick, metal, and synthetic stucco.
Can AU-1 Elastomeric Patch be used in areas that will be submerged in water?
No. It's not intended for areas that will be submerged in water or for food contact surfaces, and it should be kept from freezing before use.
What warranty does AU-1 Elastomeric Patch come with?
A 60-year guarantee. If the product cracks, peels, or separates within 60 years of installation after proper storage and application, Tower Sealants will replace it when the purchaser returns proof of purchase.
Is AU-1 Elastomeric Patch sandable?
No — the product cannot be sanded. Tool it to the desired finish and profile before it dries, since that's the only way to shape it.
