DEKS OLJE D1 works by saturating the wood and nourishing it with oil. It fills the wood's pores with oil and expels moisture and air, thus stabilising the wood and protecting it from inside, while giving a silky oiled finish.

Yes. DEKS OLJE D1 can be removed with DILUNETT

No food standards apply to DEKS OLJE D1; it is moderately adapted to this kind of use. However, we do have an oil for this purpose called OLEOFLOOR, available in a satin (CLASSIC) or matt (NATURAL) finish.

_{D1 may be applied to surfaces where it has previously been treated with D1 but all other oils must be completely removed before applying D1}

Deks Olje D1 works by penetrating the wood and literally feeding it. Filling the woods pores full of oil, expelling any moisture and air, so stabilizing the wood thus protecting it from the inside out, while giving it a rich oiled silken finish

D1 can be removed by using MARINE STRIP.

Because of the penetrating qualities of D1 and therefore the protection it offers to timber it makes an ideal primer for single pack paints and especially those used below the waterline. These paints must have mineral spirit stated as clean up in order to avoid any possible reaction with the D1

The secret of D1's success lies in it's saturation of the wood. Saturation of the wood is achieved by D1 penetrating deep in to the wood through its own natural capillary action. To aid this capillary action and assist in its penetration of the wood, it is important to keep D1 active; this is achieved by continually brushing over the same areas while applying additional thin applications of D1 until the wood is fully saturated, which is denoted by D1 flooding on the surface. As much D1 as possible must be applied the first day.

Leaving long periods between the applications of D1 will reduce the saturation of the wood by D1. This is because the first applications of D1 will have dried and sealed the pores of the wood preventing further penetration of D1 deep in to the wood thus reducing protection.

Deks Olje D1 can be applied to new wood after suitable preparation.

It very much depends on the type of caulking that has been used on your boat deck. Below is a list of caulking types that D1 will and will not affect.
D1 will not affect 2 part-caulking systems, these in general are polysulphide based
D1 will not affect Silicone or Acrylic based caulking
D1 will affect some single pack Polyurethane caulks, such as Sikaflex A1, FC and D1.

The more modern Polyurethane caulks tend not be affected by D1. An example of this would be Sikaflex 290DC. It is important with these types of caulks that they are left to fully cure before D1 is applied. A minimum of 10 weeks is the recommended period of time.
D1 will soften all bitumen based caulks

As with any product we strongly recommend that a small test area be carried out to ensure compatibility before applying D1 to the complete deck

It is not possible to give an exact answer to this question as all oils are different. However natural oils are unlikely to affect caulking, but we would always recommend trying a small area first.

If D1 has softened the caulking there is likely to be 2 reasons for this.

1 - The caulking is bitumen based and therefore not compatible with D1
2 - The caulking is new and has not been allowed to fully cure prior to applying the D1. The reason D1 softens caulking is that the oil and vapours from D1 leech in to the caulk as it dries.

Use Prepdeck undiluted on it followed by Net-trol. Prepdeck will draw at the excess tannins, which give the wood it's colour. This process may need to be done 2 or 3 times to really pale up the wood. Strongly recommend that a test area is done before

There is no problem using D1 and D2 on Plywood whether marine grade or not. However it is important that all edges where possible are saturated with D1. Why? This is because as you know plywood is constructed by gluing large veneers of wood together. This means that the D1 cannot penetrate to the inlayers as it will be stopped by the glue. Thus to prevent possible delamination of the plywood at the edges due to moisture ingress these need to be treated with the D1.
 
While D1 is a natural oil product and thus likely to have no effect on the glue used in construction of the plywood we always recommend that a small test should be carried out on a waste piece of the same ply to ensure no reaction between the D1 and glue. This is because plywood manufacturers like our industry are always looking to improve and advance the gluing and other processes used in the making of plywood and therefore we do not always or ever know what glue was used to construct the plywood.
