Coatings, Glues & Sealants
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 or drying after treatment.
- PROTIM® Optimum treated timber may be painted with alkyd based primers. 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® Optimum treated timber can be normally glued with resorcinol, phenol / resorcinol or urea formaldehyde glues, following the product manufacturer’s instructions.
- PROTIM® Optimum 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 gluing would have severe effects, it is advised that trials are undertaken to ensure performance is adequate.
Sealants
- PROTIM® Optimum treated timber is compatible with most sealants and mastics, provided manufacturers instructions are adhered to.
