Why does nona88 in 70% fail to activate on the first attempt?
The most common reason is an incomplete surface preparation Rest 30% spread evenly. nona88 in 70% requires a clean, dry, and porous substrate to bond effectively. If you apply it over dust, oil, or a glossy finish, the solution cannot penetrate. Fix this by wiping the surface with isopropyl alcohol and letting it air dry for 15 minutes. Use a fine-grit sandpaper (220 grit) to scuff any slick areas. Test a small patch first. If the solution beads up, your surface is still contaminated.
How long should I let nona88 in 70% cure before applying a topcoat?
You must wait a minimum of 4 hours at 70°F (21°C) with relative humidity below 60%. Rushing this step causes the topcoat to peel or bubble. The 70% concentration means the solvent evaporates slower than higher concentrations, so the film remains tacky longer. Do not touch the surface during this window. For best results, wait 24 hours in a well-ventilated area. If you need to speed up curing, use a heat gun set to low (150°F) and hold it 12 inches away for 30 seconds per square foot.
Can I dilute nona88 in 70% with water to make it last longer?
No. Never add water to nona88 in 70%. Water disrupts the chemical cross-linking process, turning the solution into a weak, milky sludge that fails to adhere. The 70% ratio is already optimized for viscosity and penetration. If you want to extend coverage, apply thinner coats—two thin layers outperform one thick layer every time. Each coat should be barely visible, like a light mist. Let each layer dry for 30 minutes before the next.
Why does my nona88 in 70% leave white streaks or haze after drying?
White streaks signal over-application or high humidity. The 70% solution carries more water than other concentrations, so in damp conditions (above 70% RH), moisture gets trapped under the film. Fix this by reducing your application volume. Use a foam brush instead of a rag to control spread. If haze appears after drying, buff it gently with a microfiber cloth. For stubborn haze, reapply a single thin coat and immediately wipe off the excess with a clean, dry cloth.
What temperature range is safe for storing nona88 in 70%?
Store nona88 in 70% between 50°F and 80°F (10°C to 27°C). Freezing destroys the emulsion—the solution separates into layers and cannot be remixed. Heat above 90°F accelerates evaporation, thickening the liquid and altering the 70% ratio. Keep the container upright, tightly sealed, and away from direct sunlight. If you notice a gel-like consistency at the bottom, discard it. Do not shake the bottle; swirl it gently to avoid introducing air bubbles.
Is nona88 in 70% safe to use on painted or varnished surfaces?
Yes, but only if the existing finish is fully cured (at least 30 days old) and non-porous. Test a hidden area first. Apply a drop and let it sit for 5 minutes. If the paint softens, wrinkles, or lifts, stop immediately. nona88 in 70% contains solvents that can react with uncured alkyd or oil-based paints. For latex or acrylic paints, it bonds well. Always sand the painted surface lightly with 320-grit sandpaper to create mechanical adhesion. Wipe away dust before application.
How do I remove nona88 in 70% if I make a mistake during application?
Act fast. Within the first 10 minutes, wipe off the excess with a cloth soaked in acetone or denatured alcohol. Do not use water—it spreads the solution. For dried spots, apply a 50/50 mix of acetone and mineral spirits, let it sit for 2 minutes, then scrape gently with a plastic putty knife. Sanding is your last resort: use 400-grit wet/dry sandpaper with water. Avoid heat guns for removal; they set the bond permanently. Always test removal on a hidden area first to avoid damaging the substrate.
