3M 5200 sealant will form a permanent watertight seal on timber treated with Smiths Clear Penetrating Epoxy Sealant. This allows you to achieve a dry bilge in a wooden boat, amongst many other uses.
It is also available in a Render Crack Repair Kit, along with Smiths Damp Concrete Primer, to form permanent repairs to cracks in rendered walls.
3M™ Marine Adhesive Sealant 5200 is extremely strong and retains its strength above or below water line. Stays flexible too – allows for structural movement. Has excellent resistance to weathering and salt water. Stress caused by shock, vibration, swelling or shrinking is effectively absorbed.
