{"product_id":"schluter-primer-ps-peel-stick-primer","title":"Schluter® PRIMER-PS Peel \u0026 Stick Primer","description":"\u003cp\u003ePRIMER-PS is a ready-to-use primer specifically formulated to improve the bond between Schluter's peel-and-stick membranes (DITRA-PS, DITRA-HEAT-PS, DITRA-HEAT-DUO-PS) and substrates that are harder to stick to. Think OSB, gypsum concrete, vinyl, and plywood — surfaces where the PSA alone might not grab hard enough for a permanent bond.\u003c\/p\u003e\n\n\u003cp\u003eIt's a one-component, solvent-free, water-based formula. No mixing, no additives. Pour it out, roll or brush it on, let it dry to a clear film, then apply your peel-and-stick membrane directly over it.\u003c\/p\u003e\n\n\u003ch4\u003eWhen do you actually need it?\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlways use on:\u003c\/strong\u003e OSB (including Advantech), gypsum concrete, existing vinyl or VCT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended on:\u003c\/strong\u003e Plywood in humid environments, older concrete with surface contamination\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot needed on:\u003c\/strong\u003e Clean, smooth concrete — DITRA-PS sticks directly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRule of thumb:\u003c\/strong\u003e If the substrate is porous, textured, or you're unsure — prime it.
