FAQ

What are the benefits of water based over solvent based?

Water based coatings are faster drying allowing the job to be completed faster, they have less of an odour and lower VOC contents than solvent based coatings. Brushes can easily cleaned in water.

What are the differences / advantages between water based and solvent based products

Water based coatings are faster drying, have a lower VOC content and can be cleaned in water while the Solvent based coatings have a longer working time to brush out runs and do not raise the woodgrain as much as a water based coatings. Many solvent based finishes will have slightly longer redecoration cycle than water based equivalents.

Finishes

What is an opaque finish?

An Opaque finish is a solid colour that can be used to cover colour variations and minor surface imperfections without losing the texture of the wood. An opaque stain will looks similar to paint, but as it is lower in film build the grain profile of the wood can still show.

What is a translucent finish?

A translucent finish refers to a see through coating that may be lightly coloured, or clear coating. A translucent finish is used to enhance the natural beauty of the timber and will allow the timber and grain to be seen clearly through the coating whilst it will also protect the timber against potentially damaging UV rays.

What is meant by semi-transparent?

A semi transparent coating is lightly pigmented in natural wood colours which allow the natural woodgrain to show, the final colour appearance will vary due to the natural colour of the timber, previous colours applied and the number of coats applied. Some people would refer to this as translucent.

Can I get a matt finish?

Our Dulux Trade Classic Select Woodstain which is available in many tinted colour shades and Dulux Trade Weathershield Naked Wood which is a clear translucent. Both offer a Matt finish, and all other finishes are available in mid-sheen satin.

What can I use on cladding?

A low build product such as Dulux Trade Weathershield Naked Wood is recommended for cladding as it soaks deeply into the timber and can therefore cope with the flexibility of the timber. For Opaque colours you may wish to look at using Cuprinol Trade Cladding and Fence Opaque.

It can be done but would require many coats and is not ideal. A better, more durable and solution is to use Cuprinol Hardwood Garden Furniture Stain in clear as the wax enriched formulation will help protect timber against moisture penetration. With garden furniture always ensure that the furniture is not left where water will stand upon it. Chairs and tables should be tilted when not in use to ensure water run-off. Water left on horizontal surfaces will slowly permeate into this low build film.

I would like to try and stain some plastic piping / uPVC to make a pretend wood effect. Can you advise best process?

You would need to be suitably skilled at graining effects. Our Solvent based Dulux Trade Weathershield Ultimate Opaque should adhere well, but the lifetime will be reduced before redecoration is required. Preparation is at maximum importance here, and we do not recommend deep colours on uPVC as this can attract heat from sunlight causing expansion of the uPVC material. Always do a test area in an inconspicuous area first. The uPVC must be really well degreased using a suitable a preparatory product (but not white spirit as it will itself leave greasy residue). The surface should be sanded to create a key and multiple thin coats applied until colour achieved.
