Storage / Climate
MDF is designed for interior non-structural use only and must be stored and applied in a dry area. MDF is not intended for use in areas where it may come in contact with moisture, or in climates of high humidity. Protect MDF from outdoor environments before, during and after installation. Before installation allow MDF to acclimate for 24 to 36 hours to the same approximate climate that will normally be occurring. Relative humidity and temperature are two major climate factors to be aware of. Allow floor surfaces, framing material, wall board and wall texture to dry before MDF installation.
Cutting / Fastening
When MDF is cut to length, it is recommended that you cut a fraction of an inch under the desired size to allow for natural expansion and contraction. Carbide tipped blades are recommended for a cleaner cut. Whenever possible, use nails when fastening MDF. Staples are not recommended. Pneumatic nailing guns should be held firmly against the surface of the MDF. Some testing and adjusting well be required for optimal results. A slight rise in the MDF may occur around the fastener. When this happens, lightly tap the affected area, sand and then fill with quality non-shrinking filler, as well as adjust air pressure or fastener size. Always apply MDF with a carpet or tile reveal when using for floor applications.
Finishing
For primed and raw MDF, clean to remove dust and dirt and lightly sand all surfaces to be primed or painted. Light sanding between coats is recommended. Primed MDF has been coated with a water base latex primer. Avoid using solvent based paints or pretreating MDF with any chemical such as bleach or ammonia. A high quality latex paint with a semi-gloss coat is best for aesthetics and durability.
