Product Support & Advice

Yes, the DeckWise® fastener system can be used on all high quality decking materials such as cumaru, tigerwood, massaranduba, ironwood, teak, cedar, and redwood. Use on softwoods which are thermally modified are also great for our hidden clips. Though thermally modified wood can be brittle, we recommend screwing straight down into the joist instead of a 45 degree angle such as for exotic hardwoods. Low quality materials that have high expansion/contraction rates, such as pressure treated pine should be avoided.

Q: I have a hardwood deck that has Ipe Oil® hardwood finish on it. Can I apply WiseCoat® over the top of it?
A: Yes, as long as the wooden surface is properly prepared prior to the application of WiseCoat®. The older oil finish should be removed by cleaning, stripping, sanding or power washing the surface. Once the surface has been cleaned and the old coating has been removed, WiseCoat® can be applied according to package instructions. Always test the absorbency of the cleaned/sanded wood before applying WiseCoat® by splashing some water on the prepared surface. If the water soaks in quickly, WiseCoat® can be applied. If the water beads up, you will need to sand or strip the wood until water is easily absorbed.
NOTE: If you have an old finish that was a film forming finish, we suggest sanding the surface prior to applying WiseCoat®.

Q: What about applying Ipe Oil® over WiseCoat®? Does the reverse hold true?
A: Yes, it does. WiseCoat® is non-film forming and will work fine. Just be sure the surface is once again very clean and prepped. We recommend using the 21 piece DeckWise® Deck Restoration Kit.

Q: I have an existing hardwood deck with no stain or finish on it. Can I apply WiseCoat® to it?
A: Of course! We again recommend cleaning the surface prior to application with an appropriate method such as the DeckWise® Cleaner and Brightener. Once the surface is clean and dry, WiseCoat® can be applied according to package instructions.

Slots are cut using a standard biscuit joiner tool or a router with a 5/32” slot-cutting bit with a ½” depth. The slot should be centered on both sides of the board equally. Note that some lumber yards offer deck boards with pre-cut grooves along both edges to receive edge mount fasteners.
Yes, the Hardwood Wrench™ rests on the deck joist and pries the deck boards tightly together. It is like an extra set of hands, a great help for jobs with limited numbers of installers or handling warped deck boards. This tool comes in 10 configurations and produces 1,100 pounds of board bending power.
The DeckWise® fastener automatically sets the gap spacing at the proper width between deck boards to allow for expansion and water drainage. There are 3 basic gaps the clips come in depending on the desired look. The EXTREME® line of hidden clips ranges from 3/32”, 5/32”, and 1/4” spacing.
Yes, because the stainless steel insert molded into a polymer, this reinforces the DeckWise® fastener up to 3 times stronger than other edge fasteners. It can be used on 3/4" or thicker decking.

Yes, each DeckWise® fastener system kit contains high quality stainless steel screws, wood plugs, a T-type screw gun tip, and a high speed steel drill bit. Our full line of decking screws ranges from Colormatch stainless steel deck screws; self-drilling stainless steel deck screws; composite painted head stainless steel screws, and stainless steel self-tapping metal joist screws.
Yes, the square shape of the DeckWise® fastener hidden clip allows for approximately 1" of tolerance side to side in positioning the slot above the joist. Other edge fastening methods do not allow for any tolerance in the positioning, which can slow and complicate installation.
Because the DeckWise® fastener clip is manufactured from high quality, fiberglass reinforced polypropylene, including a stainless steel insert, it is extremely resistant to screws being overdriven. The screw is left slightly countersunk for maximum holding power.
Yes, because the DeckWise® fastener does not allow screws to be overdriven, it can be removed to replace a deck board.
Yes, both the black, brown, and gray DeckWise® fasteners are 100% UV resistant as well as a salt water test for zero corrosion.
Yes, the DeckWise® fastener system is suitable for use in all climates from severe cold to extreme heat.
Many decking materials react with non-stainless screws and fasteners provided with lesser quality systems. The DeckWise® fastener system comes complete with high quality type 316 stainless steel T-type drive screws to resist staining of the deck surfaces.
No! All fastening is easily done from the top side of the deck, unlike some deck fastening systems that require the work to be done from the underside.
