It provides enough cushion to make the turf feel soft underfoot while recovering after compression so the turf performs consistently over time. For indoor turf in training facilities or outdoor covered spaces, the 12mm is the standard underlayment choice.\u003c\/p\u003e\n\u003ch4\u003eCan I glue down the 12mm underlayment?\u003c\/h4\u003e\n\u003cp\u003eYes — unlike thinner underlayments that are typically limited to loose-lay or tape, the 12mm supports full adhesive installation. Use a compatible floor adhesive spread with a \u003ca href=\"\/products\/v-notch-trowel\"\u003eV-notch trowel\u003c\/a\u003e, press the underlayment into the adhesive, and allow to cure before installing flooring above. Staple and nail installation are also supported for wood subfloor applications.\u003c\/p\u003e\n\u003ch4\u003eHow does 12mm rubber compare to 12mm cork underlayment for sound?\u003c\/h4\u003e\n\u003cp\u003eThey perform similarly in the 12mm format for sound absorption. The key difference is longevity: cork can compress and crumble over time, especially in high-traffic commercial environments; rubber maintains its density and acoustic properties for the life of the installation. For commercial applications where long-term performance matters, rubber is the more reliable choice.\u003c\/p\u003e\n\u003ch4\u003eIs the 12mm suitable for below-grade basement installations?\u003c\/h4\u003e\n\u003cp\u003eFor below-grade applications, the 12mm’s water resistance is an asset — rubber won’t absorb ground moisture. However, in basements with known moisture intrusion or slab moisture vapor transmission, a 6-mil poly vapor barrier under the underlayment is still recommended before installing finished flooring above. Always verify your flooring manufacturer’s warranty requirements for below-grade applications.\u003c\/p\u003e","brand":"Rubber Flooring Store","offers":[{"title":"Confetti - $1.88\/sqft \/ 4' x 25'","offer_id":50865433149751,"sku":"12mmRubberUnderlayment-4'x25'-Confetti","price":188.0,"currency_code":"USD","in_stock":true},{"title":"Confetti - $1.88\/sqft \/ 4' x 50'","offer_id":50865433182519,"sku":"12mmRubberUnderlayment-4'x50'-Confetti","price":376.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0846\/8021\/2791\/files\/RFS_underlay_roll_end-12mm.jpg?v=1761659263","url":"https:\/\/rubberflooring.store\/products\/12mm-rubber-underlayment","provider":"Rubber Flooring Store","version":"1.0","type":"link"}
