HPS50
HPS50 White waterborne thixotropic primer
One-pack white waterborne primer, thixotropic. Fast drying, high solids (61 %), sands well and holds on verticals without sagging. Gives a sound base for the following paint coats. Cures purely by water evaporation, contains no organic solvents.
- furniture doors and panels in various wood species
- vertical surfaces
- chairs
- children's furniture and toys where low emissions matter (catalog note for all waterborne materials)

Only to suit the gun; unthinned gives the best hiding and film build.
Clean water only (preferably demineralised). Never solvent thinners such as S50/S80. No hardener.

Stainless or corrosion-protected gun and hoses. Flush with water before and after use. Gun distance 15-20 cm, 50 % overlap. Thixotropic primer levels poorly on flats - two lighter passes beat one heavy coat on panels. recommended

- Don'ts
- Never thin with solvents - water only
- Do not add PU/acrylic hardeners
- Do not spray below 15 °C or above 70 % RH
- Do not let it freeze
- Do not flood flat panels hoping it will level - thixotropic primer flows poorly

Safety: Waterborne, no organic solvents, low odour, lower fire risk (catalog, waterborne section intro). Still wear a particulate respirator when spraying (pigment mist and sanding dust).
