Overview
Bona Classic UX is a primer that is ideal for softwoods and light coloured species such as Beech or Ash, minimises the risk of edge bonding and seals the timber to provide an even finish for the topcoat. With being non-toxic, Bona Classic UX can be safely used with under floor heating and is quick drying whilst providing an even colouration.
Bona Classic UX is not a stand alone product and has been designed to be used in conjunction with the range of Bona Varnishes:

| Bona Traffic HD | A two-part waterborne lacquer for heavy traffic environments |
| Bona Traffic HD Anti Slip | A two-part, polyurethane anti-slip varnish for wooden floors and stairs |
Preparation
To achieve the best results, wooden floors and surfaces need to be clean, dry and free of all surface contaminants such as waxes, oils, grit, dirt and dust prior to application.
- For the best results, surfaces to be treated must be sanded back to bare wood, removing the traces of any previous applications
- If necessary, apply a detergent to remove any traces of oil, grease or dirt, rinse clean and allow to thoroughly dry
- If there are any deficiencies in the surface, then repair with a suitable wood filler, such as Bona Gap Master Filler
- Remove all traces of sanding dust with a vacuum cleaner prior to priming
- If needed, wipe the project area down with a damp lint free cloth to remove any dust and allow to dry
Application
Follow the manufacturer's instructions on the container at all times and the optimal conditions are between 18-25°C during application and drying.
Note: It is not recommended to apply more than two full coats per day due to risk of excessive wood swelling. Bona Classic UX must only be used directly onto raw wood. It must not be used in conjunction with stains or oils, or to overcoat other finishes.
Species of tropical wood or softwoods, such as Teak, Smoked Oak or Wenge, contain natural ingredients, including but not limited to, tannins, oils, or resins. These natural ingredients, which can lead to lengthening of the drying time, wetting issues or colour changes and it is recommended that the timber species is identified, with a trial application carried out before coating.
- Thoroughly shake the container to blend the light pigment with the varnish primer medium
- Insert the supplied filter to avoid any contaminants, such as lumps, becoming mixed in with the Bona Classic UX
- Apply the primer evenly, using a Bona Lacquer Roller or Bona Swivel Head Applicator, avoiding accumulation.
- Care should be taken to achieve a uniform level of timber saturation to avoid colour variation
- Always maintain a "wet edge" to avoid overlaps
- Allow to dry thoroughly
- Gently abrade the dried surface with 150 grade grit or finer, remove the dust with a damp cloth and allow the surface dry
- Once the surface is clean and dry then apply another layer if needed. If not, then apply the top coat
