Painting — FAQ
What size paint mixer do I need for deck staining?
For most residential decks (200-400 sq ft), a 3-gallon mixer is ideal. Small decks or touch-ups use 1-gallon mixers. Large decks over 500 sq ft or multiple coats require 5-gallon capacity to avoid constant refilling.
Can I use any drill with a paint mixer attachment?
Most mixers require a 3/8" chuck or larger. High-torque drills (7+ amps) work best for thick solid-color stains. Avoid low-power cordless drills—they'll burn out motors struggling with heavy-bodied deck coatings.
How do I prevent splashing when mixing deck stain?
Run your drill at low speed initially, gradually increasing to medium. Keep the mixer head submerged and angled slightly. No-splash designs with curved paddles help, but controlled RPM is the best prevention.
Should I clean my mixer between different stain colors?
Absolutely. Residual pigment contaminates new colors. Clean thoroughly with mineral spirits for oil-based stains or soap and water for water-based products. Consider dedicated mixers for light and dark stains.
Helix vs paddle design: which is better for deck stain?
Paddle designs mix heavy solids faster and reach bucket corners better. Helix designs excel at preventing air bubbles in clear coats and epoxies. For standard deck stain, paddles are generally more effective.
Can I mix epoxy deck coating with the same mixer I use for stain?
Yes, if cleaned properly. However, epoxy can be harder on mixer heads. Check for wear after epoxy use. Some contractors keep separate mixers to avoid any risk of contamination that could affect epoxy curing.
