Description

Dry Fast Open Cell Antimicrobial Foam is a great-quality open cell foam, also known as reticulated foam, with a solid, firm feel. The open pores in the foam allow for water and air to pass through, making Dry Fast foam a great choice for marine and outdoor applications. Its antimicrobial properties prevent the growth of mold and mildew—another reason to choose Dry Fast for your boating and outdoor seating needs. This is not a high-density foam; therefore, it should be selected for occasional-use applications and not as berth foam for liveaboard boaters, unless breathability and superior drainage capabilities outweigh the longevity of the foam.

Dry Fast Open Cell Antimicrobial Foam’s superior airflow and heat dissipation, as well as its excellent water drainage capabilities, make it well suited for patio cushions and seating, cabin seating and mattresses. This foam has a medium stiffness, a density of 1.8 pounds per cubic foot and a foam IFD (Indentation Force Deflection) of 33 pounds.

Sailrite recommends covering Dry Fast foam with a high-performance, breathable fabric like Sunbrella for the top and sides and Phifertex mesh or Cushion underlining for the bottom to allow moisture to escape. If your cushions can be flipped, then Sunbrella, or another performance upholstery fabric, can be used on all sides of the cushion. Dry Fast is a virtually maintenance-free foam in sun, rain and even snow. Outdoor cushions will not retain water and indoor bedding feels much cooler. Professionals also suggest laminating a thin sheet of closed cell foam to the bottom of Dry Fast for the ultimate in cushion comfort and performance. Prior to lamination, poke holes with a small grommet hole cutter in the closed cell foam so the foam will drain.

The Sailrite® Blade Foam Saw expertly cuts through a full range of foam types. A standard electric kitchen knife can also be used, though the results won’t look as professional. To glue two pieces of foam together, Sailrite recommends using spray adhesive. Foam can also be glued on the sides to make a wider piece or layered to make thicker cushions. If layering foams with different stiffness levels, the firmer foam should be the bottom layer.

Please Note: Sheet size can vary up to 2 inches in length and 1 inch in width.

Important: Items are compressed for shipping, we recommend unrolling as soon as possible. Compressed foam takes up to a week to regain its original size and shape. Allow foam to fully decompress before cutting or using in a project.

Do not buy

Bought the 5” version of this product for new dinette cushions. Foam collapsed in 6 months. Sailrite said that was expected for a highly used foam of this type. Let the buyer beware.

Sailrite Response

Let us preface our response by saying that Sailrite does not carry 5" Dry Fast Foam. We believe this was purchased from another vendor. 

Your comment is true. It is the wrong foam selection for the application. The proper product would be High Density Foam. Dry fast is an occasional use product for outdoors and in boats where moisture resistance (not sponge-like) is more important than longevity, (think cockpit cushions, patio cushions, boat sleeping berths). Please do NOT use Dry Fast inside a home or even for a dinette in a boat, ever. I believe all of our support materials for foam selection cover this well.
