For wood & plywood

How to apply Wood Seal®

Block moisture. Fight termites. Protect wood.

For wooden door frames, window frames, partitions and plywood. Two coats on every face, with the faces that will sit against wall, concrete or flooring treated as the important ones — because they are.

Applying Wood Seal, step by step

  1. A gloved hand wiping sawdust off bare teak door-frame members on workshop trestles

    01 Step 1 of 6

    Surface preparation

    The film only bonds to bare, sound, dry timber. Anything left on the surface — dust, oil, grease, loose fibre — ends up trapped under the coating.

    • The wood must be clean and dry, free from dust, oil, grease and loose particles.

    • Sand back rough patches and old flaking finish, then wipe the dust off.

    • Never coat wet wood. Timber that has been rained on has to dry out first.

    • New or old timber both take the coating; the condition of the surface is what matters.

    Do not rush this — most failures start here

  2. An open 1 litre PRIME GUARD LACCO+ Wood Seal tin on a workbench, a stirring stick lifting a ribbon of the thick black coating out of it

    02 Step 2 of 6

    Stir well before use

    The protective solids settle while the tin stands. Stir from the bottom until the colour and the body are even the whole way through.

    • Stir thoroughly, lifting from the bottom of the tin, every time you start.

    • Do not thin it. WOOD SEAL is direct apply — no primer, no dilution.

    • A PRIME GUARD brush gives the best result.

    • Close the container tightly again as soon as you have what you need.

    Direct apply — no primer, no thinner

  3. A gloved hand drawing a loaded brush along a timber door-frame member, half of it already coated black

    03 Step 3 of 6

    Apply using brush or roller

    Straight onto the timber, an even coat with a brush or roller. Work to a visible wet edge so no strip of the frame gets missed.

    • Lay an even coat — flooding it on does not make it stronger.

    • Cover all sides, including the back and the edges nobody will see.

    • Give extra care to faces that will contact wall, concrete, flooring or masonry.

    • Do not let it pool in rebates and joints; brush the excess out.

    First coat

  4. Freshly coated black timber frame members drying untouched on workshop trestles

    04 Step 4 of 6

    Allow to dry 3–4 hours

    Let the first coat go off properly before the second goes on. The tin's minimum recoat window is 2–3 hours; in Kerala humidity give it 3–4 and the second coat lays down better.

    • Keep the members out of rain, spray and settling dust while they dry.

    • Touch-test a hidden edge: it should be dry, not tacky, before you recoat.

    • Do not force-dry with heat; let it cure at its own pace.

    • Leave them on trestles so air reaches every face.

    3–4 hrs before the second coat

  5. A gloved hand brushing a glossier second coat over the dried first coat on a timber frame member

    05 Step 5 of 6

    Apply the second coat

    The second coat is the one that closes the barrier. On timber it is not optional, and it goes on exactly like the first.

    • Same even coat, same brush or roller, every face again.

    • Walk the frame afterwards and check for thin spots, misses and dry edges.

    • Pay the same attention to the contact faces as you did on the first coat.

    • This is what gives maximum protection — one coat is an unfinished job.

    Second coat

  6. A finished Wood Seal-coated timber door frame with water beading across the satin black surface

    06 Step 6 of 6

    Finished good

    Allow 5–8 hours for a hard dry and full cure. Then the frame can be fixed, finished or built against, and water beads off it instead of soaking in.

    • 5–8 hours for a hard dry before installation or finishing.

    • Water should sit up in beads on the surface, not spread and darken it.

    • The barrier stays breathable, so moisture already in the timber is not sealed in.

    • Store the remaining tin closed, cool, dry and out of direct sunlight.

    Hard dry 5–8 hrs
