Preparation of substrate

The substrate must be structurally sound, clean and able to bear weight. Remove oil stains, residues which could impair adhesion such as waterproof adhesive residues, cement paste and dirt very thoroughly. Newly applied cement screeds must have a moisture content level not exceeding 4%, rough-ground anhydrite and/or gypsum based screeds not more than 0.5% (measured with CM meter).

Application procedure

Priming and strengthening of gypsum based substrates, anhydrite screeds, mastic asphalt screeds and xylolith screeds as well as screeds with old adhesive residues (not suitable with water soluble adhesive residues, e.g. sulphite liquor adhesives)

  1. Stir PCI Gisogrund well prior to the application (and/or shake 1 litre bag well).
  2. Apply a sufficient quantity of undiluted PCI Gisogrund by brush or float to achieve a uniform coat. Avoid puddles forming!
  3. Check strengthening and curing by scratching the surface. Do not apply tile adhesive, wallpaper, paint, plaster or PCI Periplan, PCI Periplan fein or PCI Periplan Tixo before PCI Gisogrund is dry.

Priming and strengthening of absorbent mineral substrates, e.g. concrete, cement screeds, gauged renders, aerated concrete, limestone or similar.

  1. Stir PCI Gisogrund well (and/or shake 1 litre bag well), dilute 1 : 1 with water and mix thoroughly.
  2. Apply a sufficient quantity of diluted PCI Gisogrund by brush or float to achieve a uniform coat.
  3. In case of very absorbent substrates it is recommended to apply a second coat of PCI Gisogrund, diluted 1 : 1 with water, to achieve a more intensive strength and to avoid blow holes forming. Do not apply the second coat until the first one has completely cured.
  4. Do not apply tile adhesive, wallpaper, paint, plaster or PCI Periplan, PCI Periplan fein or PCI Periplan Tixo as floor leveller before the primer is dry (scratch proof).


Preparation Of Substrate

Please note:

  • Do not apply at temperatures below +5 °C and above +30°C.
  • Clean tools with water immediately after use. Once cured material can only be removed by mechanical scraping.
  • In case of partial tiling the entire wall area should be primed (e.g. behind the bathtub or above the tile covering).
  • Apply only one coat of PCI Gisogrund, diluted 1 : 1 with water (consumption: approx. 100 to 140 ml of diluted mix per m²) before wallpapering on plaster/render, gypsum plasterboards etc.
  • The curing time of the wallpaper paste slows down when wallpapering on substrates primed with PCI Gisogrund. Do not paint over woodchip wallpaper etc. before the paste has completely cured.
  • The first coat of PCI Gisogrund can be diluted 1 : 2 with water in case of very absorbent substrates, e.g. aerated concrete.
  • Follow the recommendations issued by the gypsum industry regarding the maximum permissible moisture content, layer thickness of gypsumbased substrates and their surfaces.
  • Avoid puddles forming when applying PCI Gisogrund to floor areas.
  • Use particle filter mask P2 for spray application.
  • PCI Gisogrund is not suitable to prime water-soluble adhesive residues (e.g. sulphite liquor adhesives). They must either be completely removed or primed with PCI Epoxigrund 390 (sprinkle with silica sand while still wet).
  • Old adhesive residues must be completely removed before laying natural stones.
  • Do not apply PCI Gisogrund in underwater situations.
  • Use PCI Gisopakt bonding agent to prime concrete and limestone before applying plaster and gypsum lime plaster.

Are you able to ship to Australia? What would the cost be? Thanks


How many of them would you like to buy? Would this ba an order for a single product or do you want to order more of them, a pallet for example?

I think shipping is possible, what's the price and time acceptable for you that's the question.

Kind regards

David 020 7193 0953

hi do you do delivery to Perth Western Australia 6110 and if so how much. Thanks


How many of them would you like to buy? When do you need this shower tray? This is a new product in our store and we do not have it in stock yet, so the delivery of this product takes longer because it is produced only after placing the order. Production and delivery can take up to 25 days.

Please, let us know how many of them you require and we will prepare a delivery quote.

Kind regards

Do you sell the tanking liquid separately?


Yes, tanking liquid is available separately, however it's less cost efficient. Waterproofing kit is available at comparable price and contains materials that you will probably need to use anyway.

There's special category in our store: Tanking liquid.

I am happy to assist if you have any further questions.

Kin regards

David 020 7193 0953

If I order the item now. When will it come?

Hi Andrea,

It's too late for us to ship it today, but if you ordered it now we would ship it tomorrow with next day delivery.

Orders placed before 3 o'clock are shipped same day. After 3 o'clock on the next business day.

Kind regards

David 020 7193 0953

how long after manufacture can i use it. I've got 2 bags that i purchased from you last august 1 batch number 21/18. and 1 29/18. thanks

Dear Daniel,

Shelf life of the Nanofug Premium is 12 months, therefore as long as it's not been opened it can still be used within several months.

If the bags have been opened they are probably no longer usable and you will need to supply a new product.

I will be happy to assist if you have any questions.

Kind regards

David 020 7193 0953

We have the wiper tanking kit and have the instructions for the liquid and primer but nothing that says how the sealing tape/membrane is applied to this layer ? Ie: do we need to let it tac or does it go straight onto the tanking liquid ?Any advise ...

Dear Tracey,

Sealing membrane should be applied after applying first layer of tanking liquid. It works as a great adhesive to stick sealing membrane. If the first layer is already dry, you can use tile adhesive which also works well.

Everything should be covered with another tanking liquid layer afterwards.

Kind regards

David M 020 7193 0953

How do I determine the size of waterproofing kit I might need?

Dear Sean,

Joints between the tray and rest of the floor and the walls is the most important part that needs to be sealed off 3 m2˛ of waterproofing kit is enough for that, should also last to cover the tray itself with it as well with 2 coats.

If you wanted to waterproof more space, maybe even entire floor, then you should go for 6 m2˛.

I will be happy to help if you have any questions.

Kind regards

David 020 7193 0953

If I ordered 5L of PCI Gisogrund before 12.00 midday today what is the best delivery time you can provid to NP20 5AH

Dear Ken,

You can place the order before 3 o'clock to have it shipped same day.

The best what we could do is tomorrow before 9 am, but there would be additional £20 delivery fee.

We could also send it for £10 with before noon delivery.

Lastly for free for just tomorrow delivery.

Same applies for packaging of 10l. Please call me to arrange the order.

I will be happy to assist if you have any questions.

Kind regards

David 020 7193 0953

Do we use primer and tanking liquid over the shower liner or just over the joints.


The tray doesn't need to be primed. In addition to that, primer is sometimes completely optional. Primer should be used to strengthen the walls and increase it's absorption.

You should apply the primer on the floor and walls, prior to fitting the tray. It should be left until it's dry.

Then you fix the tray to the floor with adhesive, waterproof it and all the surrounding, then proceed to tiling.

In case of any questions I will be happy to help.

Kind regards

David 020 7193 0953
