TILED OR COVERED AREAS
Shower recess & wet areas (floors and upturns)
Decks, balconies, terraces & podiums
Retaining walls
Planters and landscaped areas
Structural slabs
Tanks
Pits
Water retaining structures
Suitable Surfaces:
Multithane VERTICAL is suitable for most building substrates including:
Concrete
Cement
FC Sheeting
Render
Brick and block work.
Plaster Board
Masonry
Bitumen (if primed with Duram Primeseal)
Surfaces should be sound, stable, dry, clean and free of dirt, dust and contaminants and suitably primed.
Specification
The information contained in this data sheet is general in nature and refers only to the usual use of the product and it should not be construed to be a complete specification. Site conditions vary which may require the use of the products and related products to vary. For specific projects a written specification should be sought from the Company.
Limitations
Multithane VERTICAL should only be used on surfaces that are going to be tiled or topped.
Benefits and Advantages
Multithane VERTICAL represents the highest standards in polyurethane waterproofing technology and provides the following benefits and advantages:
Single pack - no mixing.
Fast curing (usually within 24 hour)
Permanently flexible ( tests show initial flexibility of > 500%)
Suitable for immersion in water.
Can be directly tiled.
Will not bleed or stain grout or tiles.
Available in horizontal (self-levelling) and Vertical Grades (anti-slumping).
Good chemical resistance.
High strength and puncture resistant.
Provides seamless membrane (no joints or laps)
Easily repaired and or maintained.
Odourless (subjective) when cured.
Formulated to provide long term protection.
Tar free.
Easy to apply.
Has good hydrostatic resistance.
Usually grey but can be made in other colours (min qty. apply)
Precautions in Use
Risk is considered low when properly used but precautions on can, label and / or data sheets should be observed.
Do not use in confined areas with poor ventilation.
Priming and Preparation
Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of dust, loose, flaking, friable material and substances that may diminish adhesion.
In all cases the recommended primer is Primeseal although in some application where the moisture content of the surface is very low Duram Multiseal may be used.
If there is any risk of entrapped moisture in the surface, which can cause the membrane to bubble, then Duram Primeseal must be used. Duram Primeseal may be applied to slightly damp surfaces but freedom from surface water and continual dampness is essential as the product will not dry if the surface remains damp.
Apply Duram Primeseal at the minimum rate of 4 sq.m. per litre so that the area has a uniform and complete coverage. Allow to fully cure before applying the Multithane VERTICAL membrane.
Apply Multiseal at the rate of 4 sq. m. per litre, allow to cure and to apply Multithane VERTICAL within 48 hours. Ideally, surface should be primed on one day and membrane the following day.
Note: Excessively porous areas may require an additional coat.
Corners, Joins, Cracks, Gaps, Penetrations and Angles
To wall. floor corners, wall/wall corners and around penetrations apply a suitable polyurethane joint sealant / mastic to form a fillet. Joins, cracks, gaps and flange surrounds must be filled and sealed with a suitable polyurethane joint sealant / mastic.
Plastic and metal angles should be firmly embedded in a bed of polyurethane joint sealant / mastic that is gap free.
Waste outlets (pipes, flanges) should be rebated into the surface to allow water to readily drain.
Expansion joins should be filled and sealed with a suitable polyurethane joint sealant / mastic and allowed to cure. A bond breaker tape should be laid over the join and then waterproofed using Multithane UV with reinforcing fabric embedded in the membrane.
Application
Apply Multithane VERTICAL by brush, roller, broom and squeegee in a minimum of two coats, usually a day apart so that the minimum dry film thickness in 1.2mm.
If Multithane VERTICAL is used with a reinforcing fabric (say joins or upturns) the application consists of applying a base coat of Multithane VERTICAL, laying the fabric into the wet coat, working the fabric into the coat ensuring there are no wrinkles or bubbles then apply a saturation coat of Multithane VERTICAL so that the fabric is entirely saturated and covered and allowed to cure. Apply one or two further coats of Multithane VERTICAL over the area.
Coverage
The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.
Coverage / use is dependent upon type, porosity, texture and application technique.
Multithane: Generally, 1.5 to 1.6 litres per sq.m. for two coats combined, i.e. 0.75 to 0.80 litres per sq.m. per coat. Average 15 Lt pail usage approximates 10 sq.m.
Primers: Generally, 4 sq.m. per litre per coat (refer above).
Colours
Generally grey. Can be manufactured in some other colours but minimum quantities apply.
Drying and Curing
Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique and therefore drying and curing can only be given as a guide.
Curing is dependent upon temperature, humidity, type of substrate and application technique.
Generally Multithane VERTICAL dry to touch within 6 to 8 hours with full cure within 24 hours.
Storage
Keep in cool, dry place away from heat, flame or combustible material.
Product contains flammable solvents.
Class 3 dangerous must be declared prior to transportation.
Available in 5 & 15 Lt pails.
Clean Up
Avoid spills. They are difficult to clean particularly off porous surfaces.
Wet spills use a cloth and Duram Solvent. Do not clean off carpets as it is better to allow product to cure and then shave the carpet.
Equipment should be immediately cleaned with Duram Solvent.
Tiling, Topping or Top Coating
Multithane VERTICAL can be covered, tiled or topped with sand: cement mix, covered with geo-textile and pebbles or tiled which will extend its life.
If membrane is to be tiled, dry builder sand should be liberally broadcast into the last wet coat to provide a mechanical key. Allow to cure then remove any loose sand. Ensure surface is dry and clean.
Two pack tile adhesives such as Duram Tile fix - Wallaby are recommended.
Acrylic bonding agents can be used in sand: cement mixes for better strength and adhesion.
When tiling, it is essential that adequate expansion joints are installed in accordance with good tiling practice and AS3958.1-1991.
Safety & Precautions
Multithane VERTICAL is solvent based. The use of solvent resistant gloves and goggles (against splashes) are recommended.
If spraying, which is very rare, the use of self contained breathing apparatus is recommended.
If swallowed do not induce vomiting, give plenty of water to drink. Seek urgent medical advice.
If in eyes, flush thoroughly with clean water, holding lid open to ensure any trapped product may be flushed away.
If on skin, remove contaminated clothing and wash skin with soap and water.
If inhaled, unlikely due to viscosity of the product, remove person to fresh air and apply artificial respiration if required and seek urgent medical attention.
Product is flammable when wet. Keep away from all sources of ignition.
Ensure adequate ventilation. Vapours may collect in low lying areas.
For full safety data refer to the products Material Safety Data Sheet. Observe precautions as per label.
