H & B SL is a free flowing, self-levelling screed material. When combined with our ThermCon and light steel frame lattice floor joist systems, H & B SL will provide a lightweight, high performing alternative to pre-cast and in-situ concrete suspended floor solutions offering acoustic, thermal and fire protection.
H & B SL ~1750kg/m3 in weight with effective acoustic properties combined with fire protection, no smoke emissions .
H & B SL is a special, pre-blended dry mix, designed for application at thicknesses of between 35 and 60 mm.
H & B SL is suitable for floors in housing, office buildings and places exposed to similar loads. H & B SL may be applied as a levelling screed directly onto ThermCon 500 / 600 or to other substrates and may be used in conjunction with under floor heating or cavity floors. H & B SL can be covered with a floor finish such as tiles, linoleum, parquet, corkor carpet etc..
Can also be used for wet areas as bath & shower rooms!
H & B SL is designed for use as a bonded levelling screed in concrete, particle board and H & B ThermCon. In addition it can also be applied as a floating screed over thermal or acoustic insulation
or as an unbonded screed on top of a plastic membrane.
PERFORMANCE AND KEY BENEFITS
H & B SL MAKES FLOORING SIMPLE AND EASY TO APPLY and requires very little training so building teams can be efficient and get started straight away. H & B SL is a self-levelling flooring screed product, made with our organic, mineral-based binding agent. Application and drying time are quick. The result is a perfect surface ready for final treatment and finishes, i.e. carpet, tiling, wooden flooring, etc. H & B SL delivers with a lower environmental footprint than traditional cement based products.
GENERAL PRODUCT INFORMATION HANDLING & STORAGE
No special protective measures or hazardous goods protection are necessary when transporting H & B products. H & B products are generally stored in 25kg bags or as requirded according to local law and need to be protected like any other cement based material – free from moisture and humidity. Store all H & B products off the ground in a protected, dry location.
H & B products do not require any special handling equipment as they are a mineral based material without any known side effects. For safe keeping H & B material should not be stored below 5 degrees or in temperatures in excess of 35 degrees.
Avoid storing in direct sunlight.
The shelf life of H & B products if properly stored and sealed is 6 to 9 months.
Do not apply when the air temperature is below 2 degrees or over 35 degrees. H & B products must never be applied in freezing conditions where the substrate has likely been frozen.
Avoid spraying in very dry conditions as this can affect the reaction time and cause potential surface cracking. Always take into account the solar gain from direct sunlight and plan to avoid, where possible, spraying H & B products onto surfaces that are heated. If unavoidable, spraying clean water onto the surface immediately before applying H & B products is recommended. When the substrate surfaces are sustaining direct sunlight, follow the recommendations on the surface preparation.
Avoid spraying in direct sunlight.
Surfaces such as brick or concrete may need to be prepared by scrabbling or removing old, loose render. There isn’t a need to apply an expensive bonding product for better results.
You should always check that the surface is not hot due to direct sunlight as this may dehydrate the material too rapidly. If hot and dry, apply water.
When spraying onto existing surfaces, the surface must be free of all bond-inhibiting materials, including dirt, grease, formwork release oils and any other foreign matter. Any loose or damaged material must be totally removed and or repaired.
When spraying onto a light steel frame with mesh attached as per instructions make sure all mesh is thoroughly attached, check that all mesh goes to a width of 10mm of an intersection or door/window jamb. If you are spraying close to objects that need protecting from over spray, this is the time to do so.
Once our ThermCon is completed and screeded to the correct level you can commence pumping the H & B SL.
The mix is best applied using a pump, this will allow for better consistency in the mixing process. For best results an ambient temperature for mixing is between 10-25 degrees C.
Pumping is carried out in sections so that the wet edge is maintained. Use a wide aluminium screed to assist the levelling process.
The minimum required thickness of H & B products should be 35mm.
If using an under floor heating system, a minimum of 25mm over the elements is required.
Transport – No special protective measures or hazardous goods markings are necessary.
Disposal – Dispose of in accordance with local, state or federal regulations.
Clean Up – Clean tools and equipment with water immediately after use. Dried material can only be removed mechanically.
Health Hazard Information:
No adverse health effects expected if the product is handled in accordance with this Safety Data Sheet and the product label.
Symptoms that may arise if the product is mishandled are:
Swallowed: Ingesting large amounts may result in nausea and minor discomfort.
Eye: Any fine dust may be an eye irritant.
Skin: Contact with skin may result in irritation. Repeated or prolonged skin contact may lead to irritant contact dermatitis.
Inhaled: Inhalation of dust may result in respiratory irritation.
Swallowed: Rinse mouth with water. Give plenty of water to drink. Seek medical advice
Eye: Irrigate with copious quantities of water for fifteen minutes. In all cases of eye contamination it is a sensible precaution to seek medical advice.
Skin: Wash contaminated skin with plenty of water. If irritation occurs seek medical advice.
Inhaled: Remove victim from exposure. Seek medical advice if effects persist.
