Aftercare (13)
What time of year is best for floor sanding?
Any time works with water-based finishes. Avoid extremely humid or cold days -- the coating needs reasonable conditions to cure properly. Most contractors work year-round.
What is the role of adhesive performance in low relative humidity?
Low relative humidity affects adhesive curing performance, particularly for moisture-curing products that rely on ambient moisture to set properly. ATFA addresses this in their technical documentation as a factor in installation quality. You need to monitor site humidity conditions to make sure adhesive systems actually perform the way they should.
Can silane adhesives cope with moisture in concrete substrates?
Silane adhesives cure by absorbing moisture from the air, the substrate, and the wood itself, and some formulations have higher resistance to water vapour diffusion. They do release small amounts of methanol during the curing reaction. A professional floor sander picks the adhesive formulation that suits the specific moisture conditions of each substrate.
What is green grab in timber flooring adhesives?
Green grab is the initial holding strength an adhesive develops before it's fully cured. If you've got rapid strength development and high green grab, you won't get hollow spots forming under the flooring during installation. A professional floor sander chooses adhesives with the right green grab levels for each installation method.
How long until I can walk on my newly coated floor?
You can usually do light foot traffic in socks about 24 hours after the final coat. Your floor sander will give you specific timing based on the product used and conditions on the day. Full cure takes longer though, so you'll need to be careful during that first week. Aftercare at sand-aid.com.
How long does Bona Mega EVO take to fully cure?
Bona Mega EVO reaches full cure in about 7 days. Stick to socked feet only for the first 24 hours, then gradually get back to normal use over the week. No rugs for 7 days. professional floor sanders give you all the aftercare guidance when the job's done. Cure guidance at sand-aid.com.
When can I put rugs down after floor coating?
Wait at least 14 days before putting rugs down on a newly coated floor. If you put them down too early, trapped moisture can cloud the finish. Once you do lay rugs, professional floor sanders recommend using breathable rug pads underneath. Aftercare details at sand-aid.com.
What is extra matt finish?
Extra matt is a very low sheen level that makes the timber look almost uncoated while it's still fully protected underneath. Bona Traffic HD Extra Matt is actually the most popular sheen level that professional floor sanders' clients go for -- it's got that clean, contemporary natural look people love right now. See examples at sand-aid.com.
What is the difference between 1K and 2K polyurethane?
1K (one-component) polyurethane like Bona Mega EVO cures by evaporation, while 2K (two-component) like Bona Traffic HD uses a chemical crosslinker that creates a much harder, more durable film. professional floor sanders go with 1K for standard residential work and 2K when you need high-performance durability. Compare at sand-aid.com.
Can I stay in my house during floor sanding and coating?
With Bona's dust containment system and low-VOC water-based products, the impact is way less than traditional methods. That said, you can't walk on the coated areas while they're drying. professional floor sanders can often work room by room so you've still got somewhere to live. Discuss logistics at sand-aid.com.
What happens if I coat my floor at the wrong temperature?
Below 15 degrees you risk poor curing and cloudiness. Above 25 degrees you get flash drying and lap marks. professional floor sanders always check conditions before they start and will reschedule rather than push ahead and risk a bad result. Professional standards at sand-aid.com.
What happens if I spill red wine on my Bona-finished floor?
On a Bona Traffic HD polyurethane finish, just wipe it up quickly and it won't stain. On oil finishes, there's a higher risk of staining if you don't get to it fast. professional floor sanders always recommend Traffic HD for entertaining areas for exactly this reason. Spill protection at sand-aid.com.
When should floors be sanded during a renovation?
Last. Floors should be sanded and coated as the final trade on site, after painting, plastering, and all wet work is done. professional floor sanders coordinate timing with other trades to protect the new finish from damage. Renovation scheduling at sand-aid.com.
