Elastomeric Line

The Lavelast is a ready to use, paste special-based resins and fillers. 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 Lavelast maintains an exceptional 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 support after proper preparation, even on new and old bituminous, is accessible with caution.


Preparation of support

The Lavelast grips in 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.
On no-dusty,no-absorbent support,clean with alcohol or solvent.
Plastic support on the surface a bit rough with sandpaper and dusting.
On plastered walls it is recommended to apply with Murisol K (solvent insulation) very diluted and then two coats of Lavelast spread substantially, to form a continuous film.



Waterproofing horizontal (bituminous sheathing)

After you have properly prepared the support spread the Lavelast without dilution, with roller or spatula evenly. After 24hrs, a second hand and after 24hrs a third one. Expected consumption 1.5 kg/m2.
To obtain a more effective and robust waterproofing, shortly after spreading the first hand, spread the fabric F3 (non woven polyester fiber) before the 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.
Average consumption expected 2 kg/m2.

Vertical waterproofing (plastered surfaces or coated)

After properly prepared with the support Murisol K apply two coats of Lavelast within 24 hours of each other. The first coat dilute with 10% water, and the second with the 5% water. The best finish is obtained with a hair roller or brush. 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 product Lavelast on moist or wet support, nor with temperatures below +0 °C.
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 Lavelast with F3 fabric width 10 cm.
