25 Year Guarantee on LOSP Treated Pine Products
We offer a 25 Year Guarantee against Rot, White Ant / Termite attack and Fungal Decay on all LOSP pine products for above ground external use. The main stipulation is that you use
2 thin coats of oil based primer on ALL 6 sides of the product BEFORE installation. Our products must be kept dry until painted. Please allow drying time between coats.
It is highly recommended that you don’t paint your products until 72 hours have passed from delivery.
Why do you need to use an oil based primer?
The answer is L.O.S.P (Light Organic Solvent Preservative) and oil based primers have a solvent component within the paint which adheres to the L.O.S.P treatment. When you apply thin coats, this allows the paint to be absorbed into the cell structure of the timber and once the cells are blocked with the primer, the product becomes impenetrable to water.
If you wish to use Acrylic, Water Based or Oiled Based paint to finish off your products please use 2 to 3 thin coats.
LOSP stands for ‘light organic solvent preservation’ which is a type of treatment used at Karem Woodcraft to preserve your timber. The H3 is simply the level in which the timber is being treated. The level ranges from H1 to H3
Our Protim LOSP H3 treatment is a tried and trusted method of preserving timber against fungal decay and insect attack for external timber
Osmose Protim is one of the treatment processes used at Karem Woodcraft. In essence it is treatment carried out in a vacuum vessel.
