Products like 3M's 5200 work well as a water sealing caulk but will not adhere King StarBoard® to itself or other materials in a permanent bond. It is preferable to mechanically fasten or weld King StarBoard®, but when an adhesive is necessary you can use a product called Lord 7542-AB or 3M's Scotch-Weld DP-8005.
King StarBoard is the definitive marine grade polymer material. Made by the King Plastic Corporation from a proprietary process called K-Stran for flatness and consistency, it is environmentally stabilized for harsh sun and tough marine environments.
Will Seadeck stick to starboard? SeaDek will adhere to starboard, but at some point it will begin to pull away from the starboard unless the edge of the SeaDek is protected.
Mix both substances together with a toothpick, cotton swab or plastic putty knife until thoroughly blended. Apply the mixture to the area you wish to bond on one of the pieces. Press the materials together. Clamp the bonded items or find another way to keep the pieces together as the J-B Weld cures.
How to Cut Starboard
- Use a jigsaw to create curved or complex cuts in Starboard.
- Mark where you need to cut on the Starboard, using a water-based marker.
- Place a blade containing at least 10 teeth per inch into a jigsaw.
- For straight cuts, use a circular saw set for a speed of 1,275 RPM and with a blade containing at least 50 teeth.
You can use a Methacrylate adhesive (MMA) to bond KING starboard or any plastic and resin to fiberglass and gelcoat surfaces. Plexus has all kinds of these adhesives that are used in marine applications.
Can King StarBoard® be painted? No. Even polyurethanes will not hold to the material for very long. King StarBoard® is available in a wide range of colors to complement most common gel coat colors.
Fiberglass is commonly used for repairs or reinforcement on materials such as plastic, wood, metal, and even Styrofoam. Fiberglass will bond to almost any surface as long as the surface is properly prepared and scuffed. Fiberglass is applied in layers of dry fiberglass mat that's saturated with resin.
Its sanded and more gel coat is applied. Also when doing a repair or re-gel coating it's not real a chemical bond because the gel coat or glass/resin that your applying on is already cured, so it will be a mechanical bond(after you sand), but it will stick the same to gel coat or fiberglass/polyester resin
What is the best adhesive to bond fiberglass?
- Cyanoacrylate – also known as instant adhesives, super glue, crazy glue, ca glue, etc.
- Two component epoxies – Permabond two part epoxies cure at room temperature and provide strong bonds to fiberglass.
HDPE GLUE. Pro-Poly is a high strength polyethylene adhesive for coupling of HDPE pipe using standard PVC couplings, HDPE couplings and other non-standard materials. Pro-Poly is also used for bonding polypropylene, LDPE, ABS, polycarbonate, nylon, fiberglass, steel and aluminum.
Yes, it works on <some> plastics. HDPE (high density polyethylene) is OK provided it has a textured surface. Or you can rough up the surface with sandpaper (the coarser the better). Silicone, on the other hand, although not really a polymerized plastic, is a non-starter.
The Loctite All-Plastic Super Glue includes a tube of bonding agent and a bottle of surface activator. It bonds with hard and soft plastic. The glue works well with polyethylene and polypropylene surfaces.
Things You'll Need
Previously, HDPE could only be welded together by melting the surface of the HDPE. However, recent innovations have created epoxy-based glues that allow HDPE to be attached to other polymers such as PVC, fiberglass and steel.Buy a glue made for plastics. It will stick to HDPE. Hot melt adhesive for plastic will give a strong bond.
Super Glues for HDPE and LDPE Plastics (Recycling Codes 2 & 3) Both High Density Polyethylene (HDPE) and Low Density Polyethylene (LDPE) are characterised as very low surface energy plastics. Just like PET, bonding HDPE & LDPE with any old super glue will likely result in a very weak bond (or no bond at all).

Polyethylene plastic is wonderful stuff because nothing sticks to it, including epoxy. Even polysulfides like 5200 or Sika-flex won't stick to boards of high-density polyethylene - such boards must be screwed in place. But this makes polyethylene very useful when working epoxy.
