The tadelack, originally coated in the popular lime Moroccan, returns fashionably. Appreciated for its ornamental and practical aspect, the tadelack has for property to return waterproof surfaces. The originality of this filler deserves although we dedicate it a column.
In Moroccan, Tadelack has for meaning " sweetness, caress ".

Domains of Application:

Tadelack is a filler in the lime of surface which has for property to make them waterproof. He(it) will thus prove its utility in all the piéces of water, walls of room of bath, sanitary facilities... Highly-rated ornamental sound appele today Tadelack has to reveal its splendors on all the wall supports but also on the objects of decoration, the furniture...

Characteristics:

Tadelack is a part of the family of fine fillers of lime. The polishing of the lime will be made in the pebble of river or in the stainless knife. The brilliant aspect will be obtained by annexation of soft soap and eggs on the finished filler.

Materiel:

Gamate of appropriate(clean) mason, big enough.
Two mason's buckets.
A mixer for electric drill.
A trowel.
A wooden clout.
A supple(flexible) plastic spatula to squeeze(tighten) the filler.
A flat, rather wide pebble cut in two fish bones of which will be sanded to avoid marking the filler.
Some natural soft soap.
Eggs to return the brilliancy to Tadelack.
Some lime CL 90.
Some marble powder of granulométrie 1.2 and 0.8.
Pigments.

The Preparation of supports:

It is necessary to differentiate supports according to their nature:
On a blocked(surrounded) bottom, cross(spend) a glue mixed in some marble powder or more simply in some glue with stone floor applied with a spatula notched in fine set of teeth. Cross(spend) then the filler of preparation. On cellular concrete, moisten then cross(spend) the filler directly. On the opened supports, cross(spend) a distemper of lime then the filler of preparation. On a support in the lime in good condition, moisten the support and apply directly leTadelack. Indeed to prepare its support stays the best security of reussite for any work of filler in the lime. Supports must be healthy, no holes, of cracks... Make the necessities with materials adapted to find a support plan. Eliminate from the support any c residue géner the application. Ban any tracks of former(ancient) revétement such as painting, plaster...

For the application of a filler in the lime work rather in a moderate detail(room). Maintain a constant ventilation(breakdown) of the piéce aprés the stake opens it to assure a maid carbonatation some lime. We can hold environ15 liters of lime + loads(responsibilities) in m ² by cm. But the quantities are rough! It is impossible to give dosages in water, too many factors enter games but we can hold a base of 3.5 liters of water for 5 kg of mixture lime + load(responsibility). The filler must be substantial and plastic. Indeed verify the thickness and the planéité. If you have never made filler, it is maybe necessary to put guides, especially for a hypermarket(large surface). It is imperative to make the filler in the day, without join, that is why it is necessary to begin very early and maybe to work for two.

The application:

The filler will be prepared the day before as possible..
Walls ready to receive the filler of preparation..
If you wish a colored filler, you have to add pigments to the filler of finish.. Ochre will give a sweet and warm tone whereas colours in the lime will give a more intense, more modern tint(coloring). Calculate the weight of your pigments according to the weight of the lime, to avoid the saturation of colours. The saturation of colours occurs when a colour cannot be any more modified. She(it) is different according to the nature of the pigment, the lands or the oxides. We can consider the limit of saturation of colours in 20 % for lands and in 10 % for oxides. On no account, you should exceed 25 % for lands and 15 % for oxides.

The filler of preparation:

For 1 m ² and 10 millimeters in thickness, it is necessary to foresee 5 liters of lime for 10 liters of load. In mason's bucket (approximately 10 liters), mix, please, lime and marble powder. Insist on the kneading. Bit by bit, add the water while mixing in the mixer by letting the mixture become soaked, until obtaining of a substantial dough. Recover of a wet linen and let rest(pose) approximately 12 hours. Before beginning the application, mix for a long time the mortar and begin your work by resting(supporting) strongly, but without smoothing this mortar. So cover all the surface at one time. Verify the thicknesses and equalize in the clout with circular movements by resting(supporting) strongly. The surface can have a rough aspect, it is not necessary to smooth.

The filler of finish:

When the filler of preparation is still fresh(cool) with the beginning of grip, moisten him(it), without saturation, and let him(it) absorb. Begin again the operation consisting in mixing then in mixing lime and marble powder with consistency dough thickens. Take a little mortar, add your pigments, dilute in the water, let drink, mix and add this preparation for the filler. Attention, in the kneading the filler is going to thicken, thus add some water to find your consistency of departure. Insist on the kneading. Put so necessary guides and apply the filler to the lime in the clout by controlling the thickness ( no more than a centimeter), and the planéité. Do not smooth too much, what would have the effect of highlighting the soft roe. At the beginning of grip of the filler, "squeeze"("tighten") in the supple(flexible) spatula by closing the existing cracks. Go back so totally on the work by working in a precise and firm way without resting(supporting) however too hardly, always in the optics to avoid the phenomenon of gone back up(raised) by soft roe. The purpose is to obtain a very smooth filler. The effect of faïençage is completely normal. Let dry. Now the difficulty of the tadelack is going be felt. It is necessary to tighten the filler in the pebble. When that the filler seems "cracked", cross(spend) flat broke a pebble cut and polished in fish bones, in a circular way to close cracks appeared to the drying. Make all the surface of the filler. Let dry. Stay meadows of your work to tighten cracks appearing to certain places. Gauge « in the oil », but do not wait too much because cracks cannot be any more tightened and the filler will be less waterproof

Lustring or "soaping":

This operation is made after several hours, generally one day, but everything depends on climatic conditions. Your filler has to be more clear, the soft roe has do not to go back up(has do not to raise) any more to the pressure, thus watch regularly. At the convenient moment, mix a volume of soft soap for a volume of water by taking care of avoiding the soap in suspension, add if you him(it) wished, an ouf (remove the germ) which will have the effect of hardening the filler and of bringing a brilliant aspect. In the well soaked toweling, work by small surface your filler. Make penetrate into the mixture water / soap by means of the pebble which you cross(spend) in small circular movements, by insisting more particularly on cracks. Do not rest(support) too strongly but do not omit no millimeter of surface to return the waterproof filler. In the case of hypermarkets foresee of the help(assistant) because the tadelack does not support(bear) the occasions.

Your tadelack is now ended.

Use only some soft soap and some water for its interview(maintenance), in them even proportions as for the soaping, cross(spend) then a dry rag(scrap). Quite other product can damage the work.
