Step 1: Remove Loose Debris
Before applying any cleaner, vacuum the rubber floor with a soft brush head to remove dust, dirt, and loose particles. A vacuum works better than a broom because it can pull debris out of the small pores in the rubber.
- Adjust the vacuum brush height so it doesn’t scratch or mark the surface.
- A light to medium setting is usually enough to lift debris without causing damage.
Step 2: Wash the Floor
Rubber flooring is best cleaned with a mop, but not all mop types work well:
- Avoid cotton string mops or low-quality sponge mops, as they can shed fibers.
- Use a microfiber mop head for the best results.
Mix a pH-neutral cleaner (such as Zep Concentrated Neutral pH Floor Cleaner) with warm water, following the product’s dilution instructions. Mop the floor with a damp—not soaking wet—mop.
⚠️ If using a foamy cleaner (like dish soap), rinse the floor afterward with clean water. Skipping this step can leave behind a film that makes the floor look dull and attracts more dirt.
Step 3: Dry the Floor
Let the floor air dry completely. To speed up the process:
- Open windows for better airflow.
- Use a box fan to circulate air.
- Wipe up excess water with a dry microfiber cloth or mop.

5/16" (8mm) Rubber Gym Mats — 4’ x 6’ | The Balanced Choice for Weight Training & Mixed-Use Spaces
More cushion than a 1/4" mat. More affordable than a 3/8" mat. Our 5/16" (8mm) rubber gym mats are the go-to middle ground for home gym builders and commercial fitness spaces that need real protection under weight benches, cable machines, functional trainers, and light-to-moderate free weight zones — without stepping up to maximum-thickness pricing.
At 4 feet by 6 feet, these mats cover the exact footprint of a weight bench with room to stand, a single cable machine, or a dedicated free weight station. Made in the USA from recycled rubber, available in 7 colors, and backed by a 5-year warranty.
Why 5/16" (8mm) Hits the Sweet Spot
- Real cushion for moderate weight training — 8mm provides noticeably better impact absorption than 1/4" under weight benches, dumbbells, and light barbells
- Better anti-fatigue performance — standing for extended workout sessions on 8mm rubber is more comfortable than on 6mm
- More affordable than 3/8" — a smart choice when your training doesn’t involve dropping barbells from waist height regularly
- 5-year warranty on all rubber flooring
- Made in the USA from recycled tires
- Slip-resistant surface keeps equipment stable during training
- Easy to clean — sweep and mop; no special products needed
- 7 colors: Black, Gray, Blue, Blue/Gray, Confetti, Eggshell/Cocoa, and Terra Cotta
Best Applications for 5/16" x 4’ x 6’ Rubber Mats
The 4’ x 6’ footprint paired with 8mm thickness is especially well-suited for single-equipment stations where some weight training occurs but full barbell drops aren’t the norm:
- Under a weight bench — provides cushion for dumbbell sets, protects floors from plate clips and weight storage
- Under a cable machine or functional trainer
- Under a leg press or seated machine
- Home gym free weight areas with dumbbells up to moderate weights
- Martial arts and sparring areas where you want moderate cushion for footwork
- Group fitness areas in commercial settings
- Horse stall flooring — the 8mm thickness provides great cushion for hooves and easy cleaning
- Dog kennel and pet care facilities
- Locker room benches and changing area floors

Frequently Asked Questions
Is 5/16" thick enough for a weight bench?
Yes — for a weight bench used with dumbbells and barbell work at moderate weights, 5/16" (8mm) is a great fit. It handles the impact of a dropped dumbbell well and provides comfortable cushioning underfoot. If you’re regularly performing heavy barbell movements with potential drops, step up to our 3/8" mat for added subfloor protection.
What’s the difference between the 5/16" mat and the 3/8" mat?
About 1mm of rubber and a roughly $3 price difference per square foot. The 3/8" (9mm) mat is our best-selling thickness because it handles free weights and barbell work more confidently. If your training is primarily bench-based with dumbbells or cable work, 5/16" is plenty. If you regularly use a barbell on the ground or drop weights, go 3/8".
Does the 5-year warranty apply to mats?
Yes — our 5-year warranty covers all rubber flooring, including the 5/16" gym mats. It covers manufacturing defects in material and workmanship.
Can I use 5/16" rubber mats in a horse stall?
Absolutely. Horse stall rubber mats are one of the most common uses for this thickness. The 8mm depth provides great cushion for hooves and joints, and the solid rubber construction is easy to clean. Our mats are heavy enough to stay put and durable enough for daily barn use.
Is 4’ x 6’ big enough for a cable machine?
For most pin-loaded cable machines and functional trainers, yes. Measure your machine’s base footprint first — most single-column cable units have a base under 3’ x 4’, which fits within the 4’ x 6’ mat with room for the user to stand. For larger dual-cable or multi-station units, our 4’ x 8’ version provides better coverage.
