Instructions and preparation of 3003


  1. Place an appropriate quantity of 3003 into a container.
  2. Smooth the remainder of the 3003 in the original packaging and carefully close the lid.
  3. First of all mix the 3003 without water using a spatula, a trowel or a drill-mounted mixer set on low.  Then add the recommended amount of water depending on the application method (see below) and slowly mix again. BE CAREFUL of damage to the glass micro-balls if a drill-mounted mixer is set on high, you will reduce the thermal properties of the 3003 product.


  1. For applying render add approx. 5% water per 1 litre of 3003, or approx. 0,05 litres of water. Depending on how absorbent the base material is, you can carefully change the consistency of 3003 by adding more water so that it is easier to apply.
  2. For application with a roller, we recommend that you gradually add and mix in up to 25% water, i.e. a quarter of a litre of water per one litre of 3003. Depending on the absorbency of the base material and your experience you can add water to carefully change the consistency of 3003 so that is easier to apply.
  3. For application by air dilute 5 litres of 3003 with 1 litre of water (5:1). The mixture can be diluted more or less depending on the type of spray equipment and the worker’s experience.

Storage of the mixed material

  1. Smooth the mixed and unused 3003 and carefully close the lid and store in a cool place above freezing. But use as soon as possible.

Recommendations before actual application

  1. Cover the floor, windows and surrounding items before preparing the base material. You will save yourself unnecessary work when cleaning.
  2. Layers of lime and clay paint must always be properly removed (according to preparation of the base material). If you do not remove these layers of paint you will reduce the service life of the whole system if it begins to peel off.
  3. Moisten the wall before scraping off the layers of the previous lime or clay paint. If there are multiple layers, gradually moisten and remove until you reach a solid base material.
  4. Use tepid water to remove any 3003 on your hands. Use water to clean the used tools.


  • The minimum air temperature for application must not be lower than 5 degrees centigrade.
  • The optimum temperature for application and curing of 3003 is approx. 20 degrees centigrade.
  • All components of 3003 are lighter than water and the material must consequently be regularly mixed while working with it.

Final advice

  • Careful preparation helps achieve maximum adhesion and service life of the applied 3003 layer.
  • By painting over various or dark base materials, you will avoid unnecessary expense related to applying paint to the 3003 layer.

Preparation of the base material


  1. Remove non-cohesive plaster by hammering or scraping down to a solid base material
  2. Remove lime or clay paints down to a solid base material
  3. Level any unevenness using lime plaster or gypsum plaster - WARNING lime plaster requires at least 14 days to cure
  4. Apply Baselayer primer - dilute 1:10 with water and apply 1 to 2 coats depending on the absorbency of the base material


  1. Remove non-cohesive concrete in the case of old concrete
  2. Remove boarding in the case of new concrete
  3. Apply Baselayer primer - dilute 1:10 with water and apply 1 to 2 coats depending on the absorbency of the base material

Plasterboard, cetris, OSB board

  1. Treat the contact joins in the prescribed manner
  2. Apply Baselayer primer - dilute 1:10 with water and apply 1 to 2 coats depending on the absorbency of the base material
  3. We recommend you apply a base layer of dispersion paint (if possible white) for better coverage

Metal structures, sheet metal, etc.

  1. Clean the surface, remove any peeling paint and rust
  2. Apply an appropriate rust-remover or degreaser
  3. Apply primer to clean metal
  4. Paint must be roughened before applying 3003.

Glass, tiles, polished stone and other non-absorbent materials

  1. Properly clean and degrease and apply Baselayer primer - dilute 1:10 with water and apply 1 to 2 coats depending on the absorbency of the base layer

Rendering 3003

Rendering is suitable for absolutely level base materials, such as plasterboard and other large-area board materials. Plasters must be checked using lathes and levelled using a suitable putty.

Application using a float

  1. Use a stainless steel float with 5 mm notching.
  2. You will apply the required quantity of 300 by applying using the notched side under an angle of 45 degrees
  3. Spread and smooth the applied 3003 using the straight end. Work quickly and do not go back over finished areas. You can smooth over any minor rough areas the next day. The recommended correct layer of 3003 is 1 mm.

Smoothing the surface, a truly smooth surface

  1. Smoothing is possible after the 3003 is cured, the next day at the earliest (adhere to a temperature of at least 20 degrees and air out air humidity by ventilating extensively). Try everything out to avoid ruining your previous work.
  2. Use a float with Ruben, moisten it in clean water and gradually smooth over any trace of application using circular motions.
  3. Check the quality of the surface and smooth over any potential defects once more. If gouges and similar unevenness has remained after smoothing, you will have to repair the 3003 and smooth over the next day.
    If the 3003 starts to tear when smoothing over with the float, clean the float and dip in water, or possibly spray the applied material with a little water.
    Before smoothing, check that the 3003 is properly cured. Curing takes longer at low temperatures and high air humidity. Fine cracks in the wall can be filled with 3003, undiluted using a spatula.

Application of 3003 with a roller

Use a smaller roller if the base material is more uneven. This roller will copy uneven walls better and you will achieve a more even structure.

Application of various structures with a roller

  1. Use the orange moltoprene FLOCK roller (for painting). Foam rollers are too smooth and slide over the wall.
  2. To achieve the required layer thickness of 0.5 mm, you must apply 3 to 6 layers. The interval between application of individual layers is at least 6 hours. If the temperature is low or the room is not correctly ventilated, the interval between layers may be longer.
  3. Always check that the base material or previous layer is sufficiently cured in a concealed area. If not, the previous layer will be picked up by the roller. Check that you have adhered to the correct procedure for preparing the base material, according to the instructions.
  4. Apply the first and second layer with the roller so that it is as smooth as possible, using rapid motions and not much pressure. Apply the last layer depending on the structure you wish to achieve. Always try out in a concealed area.
  5. If you wish to refine the structure and achieve a smooth surface, you can smooth the surface with a Ruben float after the last layer has cured.

Determine the required number of layers on the basis of consumption, after application of the first layer.
Apply to corners and smaller details using a smaller roller first of all and then use a larger roller for larger areas. Difficult to reach areas are critical with regard to mould formation. 3003 is not harmful to health.

Air spraying

Air spraying is suitable for all base materials.

Advantages of spraying

  1. Even application over the whole area of the wall including difficult to reach areas (behind radiators, room corners).
  2. Decreased material consumption per 1 m2 as a result of spraying.
  3. Faster application, three layers necessary to achieve a sufficient layer of 1 mm can be applied over 1 day.


  • When spraying you must make sure that the mixture is diluted properly and the air is at the correct pressure.
  • High-pressure spray equipment must not be used due to the possibility of ruining the 3003 by high-pressure.
