Measuring the surface – In order to calculate the m2 of your wall you need to multiply the width by the height. For example, 4m (w) x 2.4m (h) = 9.6m2. To allow for doors and windows, simply calculate the m2 of the door or window and subtract this from the wall measuring.
Preparation of surface – Although most walls will not need preparation including those covered with cement, wood or plaster. The following will need addressing prior to application;
- Wallpaper – existing wallpaper must be removed along with the adhesives, this is down to the de-bonding attributes following exposure to water.
- Oil and heavy staining – this should be covered with an oil based paint and allowed to dry before applying Chameledec.
- Damp areas – damp will affect the adhesive qualities of Chameledec and will need to be remedied in advance.
- Flaking paints – to allow for a consistent finish, flaking paint will need to be removed.
- Gloss surfaces – PVA sealers can be used on very porous and gloss surfaces to aid the adhesion of Chameledec.
Preparation of Chameledec – To avoid any cross-contamination, you need to ensure the mixing bowl you are going to use is clean and free from any possible contaminants and then place the measured Chameledec into the bowl. Now is your opportunity to add sparkle to the mix by adding one of the twelve flecks or six glitters. Do remember to jot down the mix ratio, this will allow you to reproduce your chosen colour mix further down the line. If adding fleck or glitter, it is necessary to dry mix prior to the water being added.
Now for the fun bit. Add the appropriate amount of clean water to the Chameledec and mix by hand (yes, by hand!) until a dough consistency has been achieved. Dependent upon the quantity, this should take approximately 15 to 20 minutes. If needed, add additional water or Chameledec to achieve the ideal consistency, remembering to amend your quantity on your notes for further mixtures.
The mixture will need 30 minutes of rest before application to allow the activation of the adhesive binders to occur. After the rest period, remix the product to ensure an even colour and texture consistency has been achieved.
Application of Chameledec – Go for it! Place Chameledec onto a plastic trowel and apply to your chosen surface, smoothing it as you go to achieve a consistent coverage. We advise you to start in the centre of the wall or ceiling, allowing a bit of practice time before tackling the edges. Once you have the hand of it and are confident you are achieving a consistent finish (aim to apply 2mm in depth), move on to the edges of the surface. Do not worry about getting the product anywhere you shouldn’t such as skirting board or door frames, as due to the natural dyes Chameledec is easily wiped of any surface without leaving any marks behind.
Should you get tired, remember, Chameledec will remain in its unset form for up to 24 hours, this means you can stop at any stage and complete the application within the 24 hours. Once complete and dry, there will be no effect on the overall coverage and will not form any visual seams.
If the completion of the application takes place after 24 hours then it will be necessary to moisten the leading edge. Using a spray bottle, moisten the leading edge of the existing work back by 50mm and leave to soak in for 20-25 minutes, applying more water depending upon the thickness. This will hydrate the existing product and allow bonding with the new application.
