Prime IT MSP stabilises and consolidates the substrate surface, controls absorbency and promotes adhesion — preventing the pinholes, poor bonding and uneven curing that result from applying underlayment to an unprimed or incorrectly primed floor. A single product handles the full substrate range: \u003cstrong\u003econcrete, sand\/cement screed, anhydrite, plywood, existing underlayment, epoxy DPMs, power-floated concrete, tiles, terrazzo, steel, asphalt, painted floors and adhesive residues\u003c\/strong\u003e. The \u003cstrong\u003epink pigmentation\u003c\/strong\u003e dries to a clearly visible pink film — confirming coverage and indicating when the surface is ready to receive the next product. Also functions as a \u003cstrong\u003ecuring agent\u003c\/strong\u003e for cementitious materials when diluted 1:1 and applied by spray. \u003cstrong\u003eCoverage: up to 200m² per 5L at 3:1 dilution on porous substrates.

Without primer, highly porous substrates pull moisture from the fresh underlayment too quickly — causing pinholes, poor surface hardness and weak adhesion. On non-porous surfaces, primer provides the tackified bonding surface that allows the underlayment to grip rather than sliding or debonding on the smooth substrate. Skipping primer is one of the most common causes of underlayment failure.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003cdetails\u003e\n\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eWhat is the correct dilution for my subfloor?\u003c\/span\u003e\u003csvg stroke-width=\"2.5\" stroke=\"#008377\" fill=\"none\" viewbox=\"0 0 24 24\" height=\"18\" width=\"18\"\u003e\u003cpolyline points=\"6 9 12 15 18 9\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eThe datasheet specifies dilution by substrate type: \u003cstrong\u003ePower floated concrete, epoxy DPMs, steel, tiles, asphalt:\u003c\/strong\u003e neat (undiluted), single coat. \u003cstrong\u003eConcrete (tamped\/pan floated), sand\/cement screed, anhydrite, existing underlayment:\u003c\/strong\u003e two coats — first at 3:1 (3 parts water to 1 part primer), second at 1:1. \u003cstrong\u003ePlywood:\u003c\/strong\u003e usually 3:1, but neat for dense low-absorbency veneers. \u003cstrong\u003eCementitious backer boards:\u003c\/strong\u003e 5:1 (5 parts water to 1 part primer), single coat.
