Protim® Optimum Care and Maintenance
Use a Cut-End Preservative
All timber products should be treated in their final shape and form.
Any surface exposed by drilling or cutting must be retreated with a suitable cut-end preservative (Protim Reseal Clear or similar preservative is recommended).
Failure to re-treat may negate the value of the preservative and retreatment is a requirement of the guarantee.
Rip sawing, thicknessing and planing are not permitted unless the timber is subsequently re-treated to the original specification.
Coatings
Whatever finish you use, always check the label of the finishing product and follow the manufacturer’s instructions.
- Protim® Optimum treated timber can be coated with most industrial alkyd based joinery primers once the timber has completed flash-off after treatment.
- To achieve a durable finish subsequent on-site preparation and top coating should be as recommended by the manufacturer.
- Certain acrylic primers are not compatible with timber treated with LOSP preservatives.
- If acrylic primers are to be used it is advisable to contact the paint manufacturer or qualified agent before use.
Glues
- Protim® LOSP treated timber can be normally glued with resorcinol, phenol / resorcinol or urea formaldehyde glues, following the product manufacturer’s instructions.
- Protim® LOSP does not normally affect cured glue used to bond solid timber. However, where adhesives are to be used with structural treated timber and where failure of the bond would have severe effects, it is advised that trials are undertaken to ensure performance is adequate
- For best penetration, it is advisable to pre-treat laminates where 3 or more are used.
Sealants
- Protim® LOSP treated timber is compatible with most sealants and mastics, provided manufacturers instructions are adhered to.
