How to Seal a Garage Floor

Sealing a concrete garage floor protects it from road salt, eliminates concrete dust, makes it easier to sweep and prevents stains. It's also a great primer if you want to paint the floor.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Concrete Sealer
• Garden Hose And Nozzle
• Large Paint Tray
• Paintbrush
• Stiff Brush And Bucket
• Concrete Cleaner And Degreaser
• Paint roller with long handle and medium-nap roller coverPainter's masking tape

1. Use a hose to scrub the floor with commercial concrete cleaner and degreaser according to the manufacturer's instructions.

2. In stained areas, let the cleaner soak in for up to 30 minutes, and repeat the application as needed for stubborn stains.

3. When the floor is dry, put the sealer in a large paint tray. Use a brush to cut in the perimeter and then roll the rest with a mediumnap paint roller, equipped with a long handle. Work your way out of the garage. Apply generously but roll out all puddles. Sealer will stain surfaces, so apply it carefully and mask other areas when spraying.

4. Clean up tools with warm soapy water immediately and allow the sealer to dry as directed by the manufacturer. Do not apply a second coat.

Tips & Warnings

• Read product cautions and directions, ventilate the room, and wear protection such as goggles and a respirator mask.

on 11/22/2005 I just used Thomson's concrete sealer. This is a decent sealer for an indoor garage, the sales guy at my local Do-it-yourself store said it was cheap, this is true for external sealing.

There's a costlier product by EPOXY. I stayed away from it as it was $60 for the kit. It just cost me under $30 for Thomson's sealer, a roller, paintbrush, tray, degreaser, a pack of 10 gloves. It was an afternoon well spent and a I now have a smoother garage surface.
