Important Notes

 

1.Any colour representations within this website are as near to actual as the technology used to create them will allow. Colours and surface texture should always be selected from an actual sample prior to use.

2. The same colour may appear in several product groups, particularly within grouting compounds. Due to the varying nature of the groups this should not be construed as meaning the colour will provide an exact match. All colours regardless of their product type should be checked for suitability prior to the commencement of work.

3. Please ensure that the instructions within the latest version of a products technical data sheet are followed exactly. Technical data sheets are available within this website.

4.The numbers of tiles shown within a unit of measure are reasonably accurate allowing for average grout joints. The consumer is responsible for ensuring that they have ordered a sufficient quantity of product to complete their requirement. We cannot be held responsible for over/under supply based on the number of tiles we calculate to be in a square metre.

5. Additional quantities of tiles of any type ordered within a separate order may vary in shade or size from those originally purchased.

6. All coverage figures quoted do not include wastage and are dependent upon the condition of the surface and type of tile used.

7.It is the customers responsibility to calculate the quantity of tiles required to cover wastage, cutting and breakage. Expert advice from a trades person should be sought before ordering as these figures can vary dramatically dependent on the size of tiles selected and the fixing layout that is to be applied.

8. All quoted adhesive, grout and screed setting times are given in good faith and established in a controlled laboratory environment at 20 degrees centigrade and 50% relative humidity. This is to ensure consistent results; however adverse weather conditions or site conditions may extend or shorten these times.

9. Nicobond ready mixed paste and cementitious based adhesives and grouts used for tiling are not designed to form, in themselves, a water impermeable membrane.

10. Tiles must be fitted in accordance with the latest British Standards and The Tile Association guidelines.

11. To avoid failure which may follow from the debonding of any original adhesive, it is recommended that any residual quantities be removed to expose approximately 80%, evenly distributed, of the original surface.

12. Whatever the surface involved it must be fully cured, dimensionally stable, clean dry, and free from dust, laitance or any other contamination which will reduce adhesion.

13. Our products should not be used to make good any substrates that are either structurally weak or have a friable surface.

14. The temperature of the substrate must be carefully considered and included in your temperature calculations before using any screed, adhesive or grouting compound.

15. Gypsum and anhydrite based screeds also require careful consideration in respect of moisture content, surface finish and chemical compatibility. The screed should be tested for moisture content according to the latest British Standards and The Tile Association Guidelines. The recommended methods are Hair/Electronic Hygrometer – the test is non destructive and provides reliable results for a relative humidity of 75%. Note – Electric metres are not suitable for accurate determination of the moisture content of Calcium Sulphate screeds. It is the installers responsibility to take all necessary precautions in terms of taking moisture readings to satisfy themselves that the floor is adequately dry prior to applying any flooring products. A professional installer should be employed for the avoidance of any doubt. These screeds contain Calcium Sulphate which can be problematical if they come in to contact with cement (screed or adhesive) in the presence of moisture. Under these circumstances a chemical reaction can take place. It is necessary to create a barrier utilising a priming system or disconnecting mat unless a Gypsum based direct fix tile adhesive (such as Nicobond Gypfix) is used.

16. British Standards stipulate minimum periods for the drying or curing of certain ‘wet trade’ backgrounds. Typical substrates and the relevant information are shown below.

17. Our recommended adhesive application techniques:

Thin Bed Ceramic Wall Tile Adhesives
Spread the prepared adhesive with the straight edge of a Nicobond Notched Trowel to a maximum depth of 3mm. Reverse the trowel and comb the adhesive with the notched edge, ensuring that continuous horizontal ribs of adhesive are formed.

Solid Bed Ceramic Wall Tile Adhesives
Working up to the maximum bed thickness specified for the product spread the prepared adhesive with the straight edge of the Nicobond Notched Trowel. Reverse the trowel and lightly comb the surface of the adhesive with the notched edge ensuring that continuous, horizontal ribs of adhesive are formed. In areas of high moisture or for exterior work, the solid bed fixing method, i.e. no voids behind the tiles, must be used.

Solid Bed Ceramic Floor Tile Adhesives
The mixed adhesive should be applied with the straight edge of the Nicobond Notched Trowel up to the maximum depth specified for the product. Lightly comb over the surface of the adhesive using the notched edge of the trowel. Do not press trowel through the full depth of adhesive. Where tiles have deep keys or studs, spread the adhesive onto the back of the tile to fill the keys or spaces between the studs.

Bonding of the Tiles

Fix dry tiles immediately pressing them firmly into position with a slight sliding or twisting action. Where appropriate, the adhesive can be spread both onto the surface as described above, and buttered on the backs of the tiles. Which ever method is used, the tiles should be firmly tamped or pressed home to ensure solid bedding without voids (particularly on flooring installations). Floors should not be opened to any traffic until the adhesive has hardened. From time to time remove a tile to check that full contact has been made with the adhesive bed. Exterior installations must be protected from rain and frost until the adhesive has fully set. Where fixing is carried out in hot conditions, the finished tiling should be protected from direct sunlight to avoid premature drying. Adjustments to tiling can usually be made for between 10 and 20mins after fixing, refer to the Nicobond Tiling Products Directory for individual product information.

Mosaics
Spread a thin, even layer of adhesive and lightly comb the surface. Apply the mosaic sheet ensuring that all the tesserae are in complete contact with the adhesive. When laying paper faced mosaics, the sheets may be back grouted prior to fixing, alternatively grouting may be completed once the adhesive has set sufficiently for the paper to be removed. The use of our unique Nicobond Mosaic Adhesive & Grout will aid fixing and ensure complete uniformity of colour throughout.

Large Size Floor Ceramics
Nicobond Large Format adhesive provides a fast, convenient solution for achieving solid bed fixing of large size floor cladding and can be used at thicknesses from 4mm - 30mm. Immediately after mixing pour the adhesive on to the floor, working in small areas to avoid premature drying. Comb out with a trowel having rounded notches 10mm deep at 30mm centres and solidly bed the dry tiles into the adhesive ensuring there are no voids.

Marble, Granite or Natural Stones (Slabs and Tiles)
Whilst thinner slabs/tiles of marble or granite can be fixed using Nicobond ready mixed thin bed or cementitious adhesives, our Nicobond Natural Stone Speedflex is our preferred adhesive for larger tiles or slabs. Ensure that any dust is removed from the reverse of the slab. Spread mixed adhesive evenly onto the slab up to a maximum thickness of 12mm and to within 5cm of the edge. Press the slab firmly onto the surface with a twisting or sliding action. Remove any adhesive from slab face before it hardens. Slabs being fixed in a vertical position may require supporting during the initial setting period.

Building Regulations may also require mechanical fixing.

Grouting Notes

Ensure that the adhesive has set, that all joints are dry, clean and free from all loose materials. Check that the grout selected is correct in terms of joint width and depth and relevant to the service conditions. Do not grout more than1-2m2atatime.

Tiles with a soft glaze or Metallic finish such as silver or 18 carat gold are prone to scratching; care must be taken in the selection of the grout to ensure it is not too abrasive for the tile chosen. If in doubt always carry out a small trial prior to grouting

Tiles which have been fixed to impervious surfaces such as concrete, glazed brick, existing glazed tiles or oil based paint should not be grouted for several days after completion of fixing, this will allow the moisture from the adhesive to dry out through the joints.

Grouted swimming pools should remain empty for 3 weeks before being filled with ‘balanced’ water. Pools may be filled with salt water if desired, except where the sulphate content is very high.
Using the Nicobond Grouter or Nicobond Float Grouter the grout must be worked well into the tile or mosaic joints ensuring that they are completely filled. Immediately remove any surplus grout from the tiled surface. Before the grout sets wipe the complete area with a clean, damp cloth or sponge, avoiding products e.g. highly pigmented sponges, which may cause the grout line to discolour. Tile joints should then be finished off to the desired effect. Final polishing of the tiles may be carried out with a clean dry cloth once the film of grout remaining on the surface has dried. Allow grout to fully dry before bringing into use.

When re-grouting an existing installation ensure that the old grout has been thoroughly raked out of the joints, taking care not to damage the glazed edges of the tiles. Excessive use of water when mixing or during application may cause shade variation, efflorescence, pin holing or dusting of the grout and must be avoided.

If using acid or chemical systems to clean grouted installations grouted with cementitious products it is essential to pre-soak the grout lines with clean water. Clean water must also be used to thoroughly wash off all remaining traces of the cleaning system.

With all cementitious grouting compounds it is important to follow the recommended ratio given for mixing powder to water and to employ the same technique when finishing the grout line. Should water ratios vary excessively this can effect the final colour, as will different methods of finishing off.

For large floor areas, rotary floor scrubbing machines fitted with special squeezy blades can be used to rapidly consolidate grout into the joints and assist in the cleaning process.

Coloured Grouting
Before any coloured grout is applied we recommend that a trial be carried out on a sample tile to ensure that staining of the tile surface or tile edges does not occur since N&C Building Products Limited will not accept responsibility for staining. All the ready blended colours of our cementitious grouts are intermixable within the product group to extend the colour range. High strength pigments are used in the manufacture of all Nicobond Coloured Grouts, however care should be taken in the selection and application of cleaning and maintenance chemicals as otherwise, some discolouration may occur. Waterborne chemicals in swimming pools may cause a bleaching effect and we do not recommend the use of coloured grout, other than epoxy based material. Aggressive or unbalanced water will have a detrimental effect on any cementitious grouts and in extreme cases, any epoxy product.

 Discolouration In Tile Grouts

Tile grout is a mixture of Portland cement, fillers, pigments and additives which when mixed with water is used to fill in the gaps between tiles on walls and floors. Portland cement grouts react with water to produce complex calcium silicate and calcium aluminate hydrates which are hard and crystalline and are primarily responsible for giving the grout its strength. However due to the very nature of the Portland cement the reaction products are numerous and varied, but all contribute to the overall performance and appearance of the finished product.

Epoxy Grout

When preparing epoxy adhesives or grouts full instructions on the packaging should be followed. It is important that any liquid components which may contain pigment are thoroughly stirred to ensure good distribution. It is also essential that all components are mixed as a complete kit; do not attempt to make up part mixes as these may not subsequently cure. Do not grout more than 1⁄2 -1m2 at a time with epoxies.

The use of correct tools is essential when applying Nicobond Starlike Grout. Use the Nicobond Epoxy Float Grouter to work the grout into the dry joints, ensuring they are completely filled. Remove all excess mortar from the surface of the tiles with the edge of the float grouter. Any remaining material can be cleaned off within the working time using the correct Emulsifying pad with a little water and applying gentle pressure, working in circularmovements to emulsify the residues on the tile face. Carefully remove the resulting slurry with a squeezed out sponge, wiping the tile surface once before rinsing again in clean water. To remove any remaining film of StarlikeGrout residue from the surface, allow the grout to set for 24 hours and then apply Nicobond Resin Cleaner onto the surface. Use the white emulsifying pad in a circular motion to remove the haze. Wash off the surface with clean water and polish with a dry cloth.

Shelf Life
Unless otherwise stated Nicobond products have a shelf life of 12 months in unopened packaging from the date of packing.

Storage
Nicobond products must be stored clear of the ground and in dry conditions, protect from frost, direct sunlight and extremes of heat and humidity.

Manufacturer’s Warranty
All Nicobond adhesives, grouts and screeds are covered by our lifetime manufacturer’s warranty. If our products are proven to be defective by reason only of manufacturing workmanship we will, at our discretion, provide replacement product free of charge.

Faulty installation or non compliance with the current BS/EN Standard or The Tile Association recommendations/papers relating to substrates, the application of material and inappropriate use are excluded from this warranty and our liability is limited to the cost of replacement only on production of purchase invoice or receipt.

Calculating Grout Requirements

A useful guide to calculating the requirements of cementitious grouts for any tiling installation is as follows:

(tile length + tile width) x tile thickness x joint width

x Factor of 2
tile length x tile width

 

For Nicobond Easiclean Epoxide use a factor of 1.8kg/m2.
For Nicobond Starlike Grout use a factor of 1.8kg/m2.

An example of this would be as follows:

(330mm + 250mm) x 8 x 3

x2
330 x 250mm
Resulting Coverage = 0.34kg/m2

CE Marking of Tile Adhesives

With effect from July 2013 CE marking became mandatory for tile adhesives in the UK. In order to be CE marked, tile adhesives must comply with the essential requirements of the relevant Harmonised EN Standards set out under the Construction Products Regulation (CPR). The relevant performance targets and test requirements for CE marking are contained in the current European Standard: Annex Z of EN 12004.

The CE mark is a fitness for purpose mark linked to the essential requirements listed within the above standard and in essence is a ‘passport’ which allows our tile adhesive products to be placed on the market in any EU member state. To determine the quality of tile adhesives requires reference to all parts of the standard, whereas CE marking requires compliance with only the described annex.
