Formulated for use on both porous and non-porous substrates, walls or floors, internally or externally, ProPrimer gives professional tilers a single, reliable primer for the vast majority of trade preparation work — including calcium sulphate screeds and underfloor heating systems.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cp\u003eProPrimer improves the bond between substrate and adhesive by sealing porous surfaces and laying down a consistent mechanical key on smooth or low-absorbency backgrounds. This reduces the risk of premature moisture loss from adhesives and levelling compounds, helping installations achieve their full designed strength. Its milky white, dries-clear formulation makes it easy to see coverage during application without leaving a visible residue once cured.\u003c\/p\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eSuitable as a general-purpose priming solution before tiling, screeding or self-levelling on sand\/cement screeds, concrete, calcium sulphate (anhydrite) screeds, plaster, plasterboard and other stable trade substrates. Widely used ahead of underfloor heating installations and on both walls and floors, internally and externally.\u003c\/p\u003e\n\n\u003ch3\u003ePerformance \u0026amp; Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAdvanced polymer formulation for exceptional bond strength\u003c\/li\u003e\n\u003cli\u003eSuitable for porous and non-porous substrates\u003c\/li\u003e\n\u003cli\u003eMilky white liquid, dries clear\u003c\/li\u003e\n\u003cli\u003eUse on walls or floors, internally or externally\u003c\/li\u003e\n\u003cli\u003eCompatible with calcium sulphate screeds and underfloor heating\u003c\/li\u003e\n\u003cli\u003eNBS Source registered for ease of specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cp\u003ePair with UltraTile ProFlex tile adhesives, ProAqua Shield tanking and UltraTile self-levelling compounds for a complete, specification-backed tiling build-up from subfloor to finished tile.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eMillcot supplies genuine UltraTile trade products with full technical and safety datasheets, backed by knowledgeable trade support — helping you specify and install with confidence.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnhances adhesion on porous and non-porous substrates\u003c\/li\u003e\n\u003cli\u003eReduces substrate porosity ahead of tiling or screeding\u003c\/li\u003e\n\u003cli\u003eReady to use — no complex mixing required\u003c\/li\u003e\n\u003cli\u003eSuitable for walls and floors, internal and external use\u003c\/li\u003e\n\u003cli\u003eCompatible with underfloor heating systems and calcium sulphate screeds\u003c\/li\u003e\n\u003cli\u003eAvailable in 1 litre and 5 litre bottles to suit any size of job\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePriming absorbent sand\/cement screeds and concrete before tiling\u003c\/li\u003e\n\u003cli\u003eSealing calcium sulphate (anhydrite) screeds prior to adhesive or SLC\u003c\/li\u003e\n\u003cli\u003ePriming plaster and plasterboard walls before tiling\u003c\/li\u003e\n\u003cli\u003eImproving key on smooth, non-porous or previously tiled surfaces\u003c\/li\u003e\n\u003cli\u003ePreparation ahead of underfloor heating floor build-ups\u003c\/li\u003e\n\u003cli\u003eGeneral bathroom, kitchen and wetroom substrate preparation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit sizes:\u003c\/strong\u003e 1 litre and 5 litre bottles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Milky white liquid, dries clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubstrate types:\u003c\/strong\u003e Porous and non-porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication temperature:\u003c\/strong\u003e 5°C to 25°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication method:\u003c\/strong\u003e Brush, roller or spray, diluted according to substrate porosity per the technical datasheet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse with:\u003c\/strong\u003e UltraTile tile adhesives and self-levelling compounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003csmall\u003eAlways refer to the full UltraTile ProPrimer technical datasheet for exact dilution ratios, coverage rates and drying\/overcoating times, as these vary with substrate porosity and site conditions.\u003c\/small\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cp\u003eOne ready-to-use bottle of ProPrimer Advanced Polymer Primer, supplied in either a 1 litre or 5 litre bottle.
