Main purpose

A primer for plaster surfaces, previously painted areas including any unusual or difficult surfaces for follow up treatment of Auro paints or plasters

Use it on

Mineral substrates, plaster, clay, concrete, lime-sand bricks, brickwork, gypsum plasterboard, cement fibre boards, damp room boards, woodchip, vinyl wallpaper, glass fibre fabrics, adhesive and wettable old coatings; interior latex paints, acrylic paints or lacquer coats after a positive compatibility test.


If dealing with any uneven or difficult surfaces or unsure of what paint was previously used on the internal walls the grip coat 505 is a good option to go with. It has excellent adhesion properties and creates a stable surface to follow up with Auro paints. It is solvent free, water based and highly breathable.

Where to use it

The Auro Grip Coat 505 primer can be used on almost all normal wall and ceiling surfaces including gypsum, plaster, clay, concrete, brickwork, wood chip and vinyl wallpaper along with over old conventional or plastic paints. It is a great go to option when a surface is unusual and needs to be stabilized before painting. It is available in both 5 litres and 10 litres. 

What it does

This provides a stable base for painting over. It provides a very breathable (sd value 0.01) base which is non toxic, odour free and virtually VOC free (< 1g/Litre). It is a safe and easy to use universal primer which is preservative free.

Why we love it

Any doubts you may have about how stable a surface is can be overcome by using the Auro Gripcoat 505 – although as always it is best practice to do a test patch for compatibility. 

It ticks all the right boxes for anyone who might be sensitive to allergies and this is certified as "Allergy Friendly" from the German IUG (Institute for Environment and Health) because it has features which are favourable to people with allergies.

This Auro primer is also a vegan friendly product.

How it works

The Grip coat primer adheres on all wall surfaces, it is easy to apply by brushing or rolling. On inconsistent surfaces, the priming coat with Auro Grip coat 505 can appear slightly patchy or cloudy, e.g. on irregularly filled spots or in cases of strong or varying absorptivity, on gypsum plasterboard. This is not a flaw, just a visual aspect. Let the Grip coat dry and then paint with any Auro wall paints or plaster.

Installation Guide

This odour-free primer can be applied with a brush or roller and then recoated with all Auro wall paint. One coat is generally sufficient. It can be thinned up to a maximum of 5% with water if desired and colour can be added by using up to 10% of the 330 Full Shade Tints. Any filling that needs to be done the Auro Wall Filler 329 can be used.

For priming a highly absorbent untreated plaster such as gypsum that is in good condition the Auro Plaster Primer 301 can be used but it wont give you a white base like the grip coat. 

After priming leave it to dry for 4 – 6 hours before overcoating with any Auro Paint or Plaster as desired. 

Tools can be cleaned using water, add some Auro Plant Soap 411 as desired.

Hints and Tips

Stir the paint well before and during application.

To make coverage easier if choosing a deep/dark follow up colour it can be a good idea to use some full shade tinting colour 330 up to a max of 10% to add some similar colour to the primer. This can make follow up treatments easier as the Gripcoat primer will have some colour.
