The work, step by step
General guidance based on the manufacturer data sheets. Site conditions differ: confirm the system with MCT before you start. Where we do not name a product, ask us and we will confirm the right one.

Step 1: Test and prepare the base
Resin floors need at least 25 N/mm² concrete, 1.5 N/mm² pull-off and ≤4 % moisture with no rising moisture (Sikafloor-330 p.3, p.4). Prepare mechanically to remove laitance (p.4). The Décor system specifies a Sikafloor-161 HC primer (Sikafloor-263 SL Décor p.2); ask us which primer variant applies.

Step 2: Approve a reference area
Colour and pattern vary widely, so apply a reference area and have the client accept it before the main work (Sikafloor-263 SL Décor p.3).

Questions customers ask
Can I choose any colour?
Décor granules give an endless range of combinations (Sikafloor-263 SL Décor p.1). Approve a reference area first (p.3).
Will the floor yellow?
Use the Sikafloor-304 W clear matt sealer over Sikafloor-263 SL Décor for better UV stability and scratch resistance (Sikafloor-263 SL Décor p.2). Sikafloor-305 W has good UV and yellowing resistance (p.1).
Can my existing slab become polished concrete?
Ask us: it depends on site conditions. Sikafloor-958 PG (CZ) needs a densified surface ground to at least 400 grit (p.2, p.3).
Is it suitable for a home?
Sikafloor-330 lists residential use, interior only (p.1). These systems are for experienced professionals (p.1), so we arrange an applicator for homeowners.
