After oiling or before? How do you smooth it for finish?** A: Application before oiling is preferred otherwise Bona Gap Master may not stick to surface. Smoothing can be done after application with a wet trowel, a wet sponge, or even a wet finger.. For application on oiled or pre-lacquered surface, slightly sand the areas where the sealant has to be applied. **Q: Is this ok for laminate flooring** A: Yes , I’ve used on laminate! **Q: can this be used on stick down Vinyl floor tiles? attempting camper van conversion and few joints separated over night.** A: Good Morning, Interesting question, it is designed for use on wood or wall substrates, however it may work for your vinyl floor tiles, I could give no guarantees. I would have to recommend a test area first to check for adhesion to the flooring. **Q: Is this suitable for outdoor use? Also one reviewer said chart is out of sync. I need a light oak any suggestions?** A: Hi The Bona Gapmaster is designed for use around wooden floors and internal trims. The product is UV stable so will not break down due to exposure to sunlight. That said it is designed for internal usage and does not come with the anti-fungal properties that products designed for damp/wet areas would have. We will be uploading a better chart for colours and request Amazon to add to this listing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bona Gap Master Filler *by on Reviewed in the United Kingdom 3 August 2026* Product was as advertised ### ⭐⭐⭐⭐⭐ No shrinkage *by on Reviewed in the United Kingdom 29 November 2025* Holds up well & more importantly no shrinkage ### ⭐⭐⭐⭐ Great for the purpose, chose black for natural effect *by on Reviewed in the United Kingdom 3 May 2025* Great product, we first tried without applying masking tape on the floorboards and it made a mess. We then taped around the gaps in between floorboards,and applied the product and it turned out neat and clean. We chose black colour, so after the floorboards have been sealed with this product, it still looks natural and if the gap is still there, which is perfect for a natural rustic look. The only one thing I noticed is that it seems to shrink a bit over time, and when fully cured we noticed cracks and gaps here and there. Which we will go over . But overall great product and really recommend! ## Frequently Bought Together - Bona Gapmaster 310ml (Black) - BONA AF4411311200 Joint Sealant 310 ml Dark Oak - BONA Joint Sealant 310 ml Light Oak --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/88111540-bona-gap-master-filler-black-310ml](https://www.desertcart.jp/products/88111540-bona-gap-master-filler-black-310ml) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-24*
