|| WHAT CAN BE DONE
|| WHAT CAN NOT BE DONE
||Use a radial saw or do a small cut, to insert the plug. Fill the borders of the plugs with Mastic.
||Fill the whole of the plug with Mastic, as it must have free access to it.
|Mastic falls from behind
||We can fill the joints with polyurethane foam, paper or cardboard (only when structure is necessary).
||Fill the joints with plastic.
|Panels gets too dirty, as joint is too tight
||It can be used a silicone applicator tool, or a plastic bag (as a pastry bag)
||Clean the excess of product with cleaning product or similar, can damage the final result.
|Distance between panels
||Regular Panels (bricks, Cut Stone…) we have to bear in mind the global size of the bricks and the stones to let the enough space for the volume of the Mastic. Irregular panels (Dry Stone, Ginestar…) appro. 10 mm.
||Fix the Panels to close, we don’t let the Mastic get inside the joints.
|Brick and Rasilla joint work
||Best suggestion work is with tongue-and-groove joint.
||Let the Panels on different levels, as for its special texture would be more difficult the Mastic work.
|Slate joint work
||It is important to clad the joints of the panels at the same level and we can make small cuts to make them match and brake a too long joint.
||Apply the Mastic without texturizing with the brush, makes the joint evident.
|Two stones of different texture
||Apply the Mastic to the whole area to create a unique texture.
||Working only in the joint with the Mastic would end qwith three different stones textures.
|Creating marks and lines
||We can work on the wet Mastic to create them, before it gets hard, a small brush or knife can help us.
||The use of any abrashive product.
|Material is transparent
||Paint can be applied, when the back of the panel can have a small lack of compactness, using a darker paint will cover it.
||Adding no translucid materials.
|Installing different tone color panels
||Paint all the joint and balance the tonality of bricks or stones. Use rags or patinas to achieve a realistic tonality.
||Painting only the joint, stones or bricks affected.
|Jointure / Panels is shiny
||We can reduce the shine of a panel by using low parafines disolvents or by sanding out the area, apply a very small layer of matt plastic paint.
||Applying more Paint layers without diming the shiny parts.
|Paint does not get fixed
||Using a degreaser can help us to remove the bad paint and prepare the are to paint it again.
||Using aggressive degreaser.
|Color is too dark
||If color is too dark or not too natural, we can dime the tone color with a rag and a bit of acetone, using the Joint color we can shade and blur.
||Applying layers of clear colors.
|Installing next to heating areas
||Panels are manufactured and dry through a temperature process between 140/180 ºC without getting in flames. Panels can show more soften from temperatures up to 70 ºC. ORIENTATIVE FIGURES.
||Cladding the panels too close of heat places with extreme temperatures, close to flames, inside a chimney nor similars.
|Colour does not paint
||Mix the powder in the bottle cans very good, do not shake. Mix using a mixer, brush, etc.
||Insist to apply more and more coats.
|Mastic is dry
||Remove the first dry layer of the Mastic and use the rest as normal.
||Mix all the Mastic as dry parts will be affect the rest.
|Mastic is too liquid
||Apply the catalyst to the hard Mastic and wait for its reaction, then work as normal by calculating the drying periods of time.
||Apply it directly as it will drop from the handled “spatula”.
|Joints are arched
||We can adjust these arched joints by adding more screws to the jointures.
||Try to solve the difference with the Mastic.
|Joints do not match
||Some panels its jointures can not match or be simetric, we can adjust this while making small cuts and filling it with Mastic.
||Try to cover all the stones with the Mastic, we will obtain a non regular union without form.
|Panels is broken
||After cladding the panels correctly to the surface we can repair the damages by adding Mastic.
||Cut the broken piece as measurements of the panels will be different and harder to have a good joint work.
|Red lines found in some stones
||Paint over with the color, if we can not do it, then use some Mastic and paint on top.
||Use aggressive dissolvent to remove the lines.
|Panels have “bubbles”
||As much as we can, we can place the screws in the “bubbles”. We then cover everything with Mastic.
||Painting the “bubbles”, we need first to cover it with Mastic.
