Work in one direction to minimize bubbles. On SLA prints with fine surface detail, use a soft brush and light pressure to avoid filling fine recessed details with excess resin.

Partially cured resin will inhibit coating adhesion and can cause the coating layer to remain permanently tacky.\u003c\/li\u003e\n    \u003cli\u003eClean with fresh IPA, not used or contaminated IPA wash solution. Contaminated IPA deposits residue rather than removing it and will cause adhesion failure.\u003c\/li\u003e\n    \u003cli\u003eApply coating in thin layers. SLA prints already have a good surface quality and do not need thick coating applications. A thin coat self-levels better and cures more evenly than a heavy application.\u003c\/li\u003e\n    \u003cli\u003eUse a soft brush on highly detailed models to avoid filling fine recessed details with excess resin. A stiff brush pushes resin into detail areas rather than laying it over the surface.\u003c\/li\u003e\n    \u003cli\u003eAvoid coating in high humidity environments. Humidity above 70% can cause surface cloudiness in UV coating resins. If cloudiness appears, it is likely moisture contamination — sand lightly with 800-grit, clean, and re-apply in a drier environment.\u003c\/li\u003e\n    \u003cli\u003eFor clear or transparent SLA prints, Build Coat cures water-clear and maintains the optical clarity of the base resin. Avoid using Tenacious on clear prints as the slight tint in Tenacious can reduce optical clarity.\u003c\/li\u003e\n    \u003cli\u003eFor miniatures and highly detailed prints, warm the Build Coat bottle in warm water for 1 to 2 minutes to reduce viscosity slightly before application. This improves flow across fine details without requiring dilution.\u003c\/li\u003e\n    \u003cli\u003eRotate the part continuously during UV curing to ensure no shadow areas remain uncured, especially on complex geometry with overhangs, recesses, or undercuts.\u003c\/li\u003e\n    \u003cli\u003eFor functional parts that will see regular handling, two coats significantly improves long-term durability and scratch resistance compared to a single coat.\u003c\/li\u003e\n    \u003cli\u003eIf the cured coating appears soft or tacky after the full cure time, extend UV exposure in 1-minute increments. Persistent tackiness usually indicates under-cure from insufficient UV intensity or shadowed areas that did not receive direct exposure.\u003c\/li\u003e\n    \u003cli\u003eFor outdoor or high-UV-exposure applications, apply two full coats of Build Coat for maximum UV barrier thickness.

UV coating resin adheres well to fully post-cured SLA prints when the surface is clean and free of contamination. The key requirement is that the SLA print must be completely post-cured before applying any coating. Applying coating over a partially cured SLA print can cause adhesion failure, surface wrinkling, and inhibited curing of the coating layer. Clean the surface with fresh isopropyl alcohol, apply a thin even coat of Siraya Tech Build Coat, allow to self-level for 30 to 60 seconds, then cure under UV for 2 to 5 minutes.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eDoes coating resin bond to SLA resin prints?\u003c\/summary\u003e\n      \u003cdiv class=\"st-faq-body\"\u003e\n        \u003cp\u003eYes, with proper surface preparation. UV coating resins bond chemically to the surface of SLA resin prints through secondary polymerization, where the coating resin bonds to residual reactive groups on the surface of the cured print. This bond is strongest when the surface is clean and when the base print is fully but not excessively post-cured. A surface that is over-cured to the point of full surface saturation may need a light sand with 400-grit before coating to restore surface reactivity and improve adhesion.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow do I stop my SLA resin prints from yellowing?\u003c\/summary\u003e\n      \u003cdiv class=\"st-faq-body\"\u003e\n        \u003cp\u003eThe most effective way to slow or prevent yellowing on SLA prints is to apply a UV-stable coating resin such as Siraya Tech Build Coat immediately after final post-cure. The coating acts as a UV barrier, absorbing and blocking UV radiation before it reaches the base resin. Store coated prints away from direct sunlight and UV sources when not on display. For clear or water-white resins where yellowing resistance is the primary concern, two coats of Build Coat gives the best long-term protection.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eCan I paint over SLA coating resin?\u003c\/summary\u003e\n      \u003cdiv class=\"st-faq-body\"\u003e\n        \u003cp\u003eYes. Fully cured Siraya Tech Build Coat provides an excellent surface for paint adhesion. The smooth, sealed resin surface accepts standard acrylic primers and paints easily. Allow the cured coating to harden for at least 30 minutes after UV curing before applying primer. For miniatures and scale models, the sealed coating surface gives more even color with fewer paint layers required compared to painting directly on bare SLA resin.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow do I get a glossy finish on SLA resin prints?\u003c\/summary\u003e\n      \u003cdiv class=\"st-faq-body\"\u003e\n        \u003cp\u003eApply one to two thin coats of Siraya Tech Build Coat after final post-cure.

Two coats gives a deeper, more consistent gloss than one coat, especially on prints with any remaining micro-surface variation.
