Buying Guide
What size kit do I need?
Assess your garage area in square feet and choose a kit that covers the space with a single coat or requires minimal layering. Larger garages typically benefit from 2.5 Car Kits, while smaller spaces can use 1 Car Kits. Be sure to verify the kit’s coverage per pouch and total pouches.
Which finish should I pick?
Glossy finishes look brighter and easier to clean but may reveal dust and imperfections. Matte or textured options reduce glare and hide minor flaws but can be harder to clean. Consider traffic levels and aesthetic goals when selecting color and texture.
How long does it take to cure?
Most RockSolid kits offer walk-on readiness in 8-10 hours and vehicle readiness within 24 hours, depending on temperature and humidity. Plan for curing time without footwear or cars parked on the surface for the initial period.
What about odor and VOCs?
Low odor and low VOC formulations help make installation more comfortable. Ensure adequate ventilation during application and curing, especially in enclosed spaces like garages and basements.
What prep is required?
Proper substrate preparation is essential. Remove oil, dirt, and moisture, and repair cracks or defects. A clean, dry, and structurally sound concrete surface improves adhesion and longevity of the coating.
Color and compatibility considerations
Color choices should align with the space’s lighting and surrounding decor. If compatibility with existing coatings is uncertain, consider applying a clear top coat or selecting a match that is compatible with bare concrete or existing coatings.
FAQ
Are RockSolid coatings suitable for basements?
Yes. They are designed for interior concrete surfaces, including basements, garages, and workshops, with durable, chemical-resistant finishes.
Can these kits be used over existing coatings?
Many kits are described as buildable and capable of covering coated concrete, but verify the product data for compatibility with existing coatings to ensure proper adhesion.
How long after application can I park a vehicle on the floor?
Typically 24 hours after application, though this can vary by kit and environmental conditions. Always follow the specific curing instructions on the product label.
Do these kits require professional installation?
No. RockSolid kits are designed for DIY use, but thorough surface preparation and adherence to mixing and curing times are essential for best results.
What maintenance is recommended after installation?
Regular cleaning with non-abrasive solutions and prompt attention to stains help maintain the finish. Avoid harsh solvents that can degrade the coating over time.
