The building must be weather-tight prior to the placing of any screed material: the roof; external doors and windows must be in place and closed or covered and taped to prevent draughts. All substrates must be suitable to receive the screed as per current good working practices. Consult our substrate preparation guide for full details before use. The substrate must be structurally stable and free from deflection or excess movement, it may be composed of: sound concrete or screed; suitable timber; ceramic tiling; or existing resilient flooring. It must be thoroughly clean, dry, and free from laitance, grease, oils, paint, or other contaminants which may impair adhesion.
Suitable mechanical preparation of substrate may be required. Air and substrate temperatures must be greater than 5°C. Relative humidity value of the floor must be less than 75% and a functioning DPM in place when moisture sensitive finishes are to be laid onto the Larsen SLC 3015 Fast. Existing movement joints should be carried through the SLC3015 Fast, preferably with proprietary joints. When applying over heated screeds a suitable 5-10mm PE foam expansion strip should be fitted to the full depth of screed around the entire perimeter of the floor. It is recommended to install movement joints where there is a step change in depth or a significant change in substrate.
Normal concrete/screed requires priming with Larsen Acrylic Primer diluted 1:1 with clean water. Particularly porous concrete/screed requires priming with Acrylic primer diluted 1:1 with clean water followed by a coat of Acrylic primer applied neat. If the relative humidity value of the floor is greater than 75%, Larsen DPM should be used. DPM may be primed when cured with Larsen Primer Grip 360. Timber floors must be free from deflection and be suitably stable. Existing floorboards should be overlaid with minimum 15mm exterior grade plywood, screw fixed at 300 mm centres. OSB may be used on floors but must be flooring grade, rigid and screw fixed at 300mm centres, the surface should be sanded to remove any wax or similar treatment and then primed. WBP plywood may be used but due to the variability in quality, extra care should be taken. It is recommended that WBP sheets are sanded and primed. Edges of all timber sheets should be supported by joists or studs and where possible timber sheets should be tongue and groove. In wet areas timber should be suitably tanked. All timber substrates should be primed with one coat of Larsen Primer Grip 360.
In all cases, allow primer to dry before applying Larsen SLC 3015 Fast.
Due to the rapid setting characteristics, take care to ensure product can be mixed and applied continuously so as not to create a cold joint in the floor. Add approx 4-4.5L of clean water per 20kg bag (sufficient to achieve target flow without bleed or settlement). Mix with a heavy duty drill and paddle for 1-2 minutes. Excess water will cause a loss of strength and the risk of bleeding or a weak finish.
Pour the mixed product over the floor. SLC3015 Fast will level out to a smooth finish. Where necessary, release air bubbles with a trowel or spiked roller. This practice must be carried out quickly, within 3-5 minutes of application. Larsen SLC 3015 Fast can be applied up to 15mm.
Should any trowel marks remain, remove with a carborundum stone after ½ – 1hr.
Drying is dependent on the application thickness, absorbency of the substrate, substrate temperature and site temperature and relative humidity. Typically SLC 3015 FAST can be walked on after 30min and adhesives can be applied onto the surface as soon as it is sufficiently hard not to be damaged by the trowel. This is usually after approx 45 minutes but may take longer depending on site conditions and when applied onto DPM or other non-absorbent substrates.
All work should be carried out to current best practice, trade body advice and BS8204. Larsen Professional SLC 3015 FAST is not suitable for industrial use, should not be applied to flexible surfaces and cannot be used as a final wearing surface. Larsen SLC 3015 FAST is suitable for use over underfloor heating systems. Room and substrate temperatures should be above 5•C during application. Drying times are dependent on screed thickness and site conditions. Always test moisture contents before laying impervious floor coverings. Protect surface from draughts, strong direct sunlight and following trades until covered.

Larsen Acrylic Primer is a ready to use primer for use on porous and difficult substrates prior to tiling or screeding, or to seal gypsum plasters or screeds prior to the addition of cement based adhesives.
It can be used neat when sealing substrates or diluted with an equal quantity of water for general priming.
It’s a hybrid primer for the ultimate mechanical key. It is a high performance bonding agent specifically designed for tiling and flooring installations. Formulated with advanced polymers and special fine aggregate, it is a universal multi-purpose primer. Larsen Primer Grip 360 is designed to provide an improved mechanical key to all common absorbent and non-absorbent backgrounds including plaster, plasterboard, timber, concrete, epoxy DPM, flooring grade asphalt and glazed tiles. Larsen Primer Grip 360 is rapid drying and can be tiled over or levelled in as little as 15-20 minutes.
Fantastic customer service and fast delivery, highly recommend
Great prices and a super quick delivery turnaround. Communication was perfect aswell. So much so I’ve ordered again.
They actually answered the phone, were polite, knowledgeable and the order was delivered in full and on time. Would fully recommend both on price and service. Thank you.
BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
Great service, great price and great communications. We will definitely use Buy The Pallet again
