Wait for grout/mortar to cure (5-7 days for most, 7-14 days for cotto). Then: 1) Remove cement haze with appropriate cleaner (MN Builders' Clean for stone, KF Cement Residue Remover for tiles). 2) Rinse thoroughly and allow to dry completely (24-48 hours). 3) Apply appropriate impregnator (MN Stain-Stop for stone, KF Protective Impregnator for tiles, TC Impregnator for cotto). 4) Remove excess within 10-15 minutes. 5) Allow 24 hours to cure before use.

New concrete must cure for a minimum of 28 days before sealing. During this curing period, the concrete is still chemically reacting and releasing moisture. Sealing too early traps moisture inside, which can cause: efflorescence (white salt deposits), delamination of the sealer, and reduced concrete strength. After 28 days, clean with MN Power-Clean, allow to dry completely, then seal with MN Stain-Stop or MN Concrete Coating.

Apply sealers and impregnators when: Temperature is 5-25°C. The surface is completely dry (no rain for previous 48 hours). No rain expected for next 24 hours. Not in direct sunlight (product evaporates too quickly). Not in frost. Best months in Northern Europe: May-September. Best time of day: morning or late afternoon (avoid midday sun). For cleaning (ALGEX, Outdoor Cleaner): similar conditions but slightly less critical - just ensure the surface is dry and no rain for 24 hours after application.

After grouting is standard practice - seal once the grout has cured. However, pre-sealing before grouting can be beneficial for very porous stone (sandstone, some limestone) to prevent grout from staining the stone surface. If pre-sealing: apply one light coat of MN Stain-Stop, allow to cure 24h, then grout. After grouting and curing, clean cement haze, then apply the full sealing treatment. Note: pre-sealing adds cost and time, so it is mainly recommended for very porous or light-coloured stone.

Clean grout with KF Grout Cleaner after installation (once cured). Then immediately apply KF Grout Protector - this is the key step. The protector prevents dirt and moisture from penetrating the grout, keeping the colour consistent for much longer. Re-apply every 1-2 years. For grout that has already discoloured: clean with KF Grout Cleaner first to restore original colour, then protect. In wet areas: KF Mildew-Away first if mould is present, then clean, then protect.
