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. It stays flexible too allowing for structural movement. Has excellent resistance to weathering and salt water. This effectively absorbs stress caused by shock, vibration, swelling or shrinking.

Currently we only stock the product in white. We can order other colours in case quantities (12) if required. We have started stocking both regular and fast cure but we ONLY recommend the regular cure for render crack repairs as the fast cure can release gasses whilst setting under some circumstances.
