Strap Clamps For Hardwood Floors - Tips
Strap clamps are predominantly used with glue down floor installations that don't fit snug before the glue has a chance to set. They have also become an invaluable tool with the growing number of our long length and wide plank hardwoods offered today. Shown to the right is an illustration of a coiled strap clamp manufactured by Crain Tools. Areas as large as 18 feet across can be brought together for a tight fit with this ratcheting mechanism.
Strap clamps were initially used in the flooring industry when glued laminate floors became popular. Nowadays these tools have been recognized by many professionals and are being used with other forms of installation, particularly direct glue downs.
How Are Strap Clamps Used?
Realistically when installing the first few rows can be glued, tapped together, then taped using blue painters tape. When the installation proceeds further into the room, place one side of the clamp (flat piece with curled edge attached with strap in photo above) on the edge of the starting area. It will overlap the edge. On the other end we want to engage the other part of the strap clamp near the end joints. Considering these strap clamps can be expensive here's a tip in case you have a product with many shorter pieces.
When extending the strap across the installed area grab a few longer scrap pieces (arrow), engaging them by tongue and groove on the last row without glue. By covering a few end joint areas with one longer board you've cut down on the clamps needed. The ratcheting mechanism and pressure should pull all the side joints tight, without the need for extra clamps.
How Long Until The Glue Dries?
Generally a few hours. Our higher quality products may just need additional taping once the floor is pulled tight. Be careful with the ratcheting system. Too much pressure can heave the boards near the last completed area. If additional pressured is needed, weights (extra boxes of flooring) can be applied across the last few rows that were laid.
How Many Strap Clamps Are Needed?
