Extra Lavelast

Elastomeric Line

The Extra Lavelast is a ready to use, paste special-based resins, fillers and glass fibers to ensure greater elasticity than Lavelast. The product spreads like a traditional painting, when it is dry to form a continuous film very tenacious and resilient and well clinging to support. The Extra Lavelast maintains a unique degree of elasticity to both high and low temperatures and long-lasting.

It is also waterproof, while retaining sufficient vapour permeability and is used as a protective or decorative painting in all those cases where you can get cracking and movement of support: after proper preparation, even on new and old bituminous sheaths, is accessible with caution.


Preparation of support

The Extra Lavelast grips on any support, as long as the same is not dusty, brittle or presence of grease, oil, etc.
On iron support before applying you should treat with antirust.
On wooden support make sure that it is well dry and dusted.
Plastic support: on the surface a bit rough with sandpaper and dusting.
On no dusty, no absorbent support, clean well with alcohol or solvent.
On plastered walls it is recommended to apply with Murisol K (solvent insulation) very diluted and then two coats of Extra Lavelast consistently stretched to form a continuous film.



Waterproofing horizontal (bituminous sheathing)

After you have properly prepared the support spread the Extra Lavelast without dilution with roller or spatula evenly. After 24 hours apply a second coat and after 24 hours a third coat. Consumption expected 1.5 kg/m2.
To obtain a more effective and robust waterproofing, shortly after spreading the first hand (or part thereof) spread the fabric F3 (non-woven polyester fiber) before the Extra Lavelast dryes.
Be careful to overlap the various bands of fabric at least 2-3 cm.
Brush up on with a brush, roller or mops to soak in Lavelast.
Average consumption expected 2 kg/m2.

Vertical waterproofing (plastered surfaces or coated)

After properly prepared with the support Murisol K, apply two coats of Extra Lavelast 24 hours apart from each other. The first coat dilute with 10% water, and the second with the 5% water. The best finish is obtained with a sponge roller or brush bristle. It forms a smooth or slightly wavy with very light skin. Average consumption 0.5 kg/m2. You will get a smooth and shiny-satin. Do not apply the Extra Lavelast on damp or wet products, nor with temperatures below 0C..
Store the product cool, but protected from Frost. If the facade there are crackles or cracks, you should open the crack, caulk with adhesive and apply a coat of Extra Lavelast with F3 fabric 10 cm width.
