How do you prepare for using Larsen SLC 2500 External?
Do not use Larsen SLC 2500 if rain is expected within 8 hours, or if freezing temperatures are expected within 24 hours. You must protect working areas from debris, dirt, dust, and loose particles, until SLC 2500 External Screed has ‘gone off’ – hardened. In accordance with ‘good working practices’ tt is important to ensure that the concrete or screed surface must be suitable to receive the screed, i.e the substrate must be clean and sound.
Heavily trafficked areas or old damaged substrates must be prepared with grit shot blasting or water jetting, to provide a suitable mechanical key. All residue must then be removed to provide a dry, dust free open textured surface free from latency, surface treatment and other contamination.
It is important to ensure that the air and substrate temperatures are +5 degrees before beginning, the surface tensile strength of the substrate should also be a minimum of 1.0MPA.
Do I need to prime before using Larsen SLC 2500?
It isn’t necessary to prime non-absorbent surfaces, however, to ensure satisfactory bonding, the prepared surface should be dampened down to minimise pin-holing. You must ensure that the surface is saturated, but there must be no pooling or ponded water prior to starting application.
SLC 2500 External should not be applied to flexible surfaces, brick paving, bitmac or asphalt. Do not place when substate temperatures are below 5 degrees or ambient temperatures are below 10 degrees and falling. Do not apply above 25 degrees. Extra water should not be added to the mix. If material thickens before it is applied it should be discarded. Protect from direct sun, when applying and curing. Do not apply in excessively windy conditions. do not apply during rain, or when rain is forecast. Protect from frost. do not exceed the maximum recommended water content.
