Filling Cracks & Gaps In Hardwood Floors

When filling holes and gaps for example down the length of the side of a door, what is the difference between polyfiller and wood filler. For deep areas, fill with wood or sawdust, then put in the epoxy to avoid having a boulder of material (epoxy in this case) that will definitely not move at the same rate as the wood. Epoxy has the advantage of being waterproof and does a good job filling gaps in wood. Jameson, it depends how big the space between is. Likely you’ll need a filler piece of wood for any significant gap. I had tried on another piece with same joints to fill with PVA glue and sawdust (as the back of the glue said) and that looked very bad and rough. Try an epoxy like WoodEpox or Minwax Hohh Performance Wood Filler to fill the gaps.

It was stained with a very dark color, and I’ve used stain remover and sanding to get it down to the wood as far as I can. Be especially careful when using a water based gap filling product, the dust needs to be as fine as possible due to the fact that the filler mixture and the dust will not bind together correctly if the dust is too coarse – just be aware and be careful. The softest wood yields to the pressure so it rarely does that but it can if the above problems are not attended to.filling gaps in wood

For the time being, we are going to talk about filling the gaps between a barrel and the side flat in a barrel channel. I helped refinish some really ancient wood floors in a farmhouse that were extremely wide probably close to 200 years old. Attaching the final trim pieces with brad nails will leave holes to be filled, and even the holes made by fine 23-gauge pin nailers can sometimes benefit from a touch of filler. Using some new water repellents and drainage aids, I believe you can get strips of wood to last at least 30 or 40 years, if not more.

Most other fillers are NOT that forgiving and you will have to sand the stuff out of the wood. The combination of the epoxy and the wood dust should give you enough volume to fill your gap. Also the filler must be sanded off the surface of the floor once it has dried and its easier to sand off the filler with 100 grit on a floor that has been sanded with 100 grit, before filling, than a floor that has been sanded with 80grit.

Now using a soft mallet, hit the strip of wood down into the gap to create a air and dust tight seal. I have been able to close up pretty big gaps by rubbing glue over the gap then burnishing the edge with a screwdriver shaft. I used it on my kitchen cabinets before I painted them, the spot below the sink where water had dripped down over the years and pulled some of the wood away. After it sets it scrapes off easily, as outside of the joint it doesn’t soak into the wood. There are times that you will be faced with the need to repair a special piece of wood that contains a range of colours.

Glue and sawdust: Using a mixture of wood glue and sawdust to fill a hole or crack in a project allows you to match the wood you’re working with exactly because you use sawdust that created while milling the boards for the project. Inserting wood more or less garuntees that the filler won’t fail if still needed and will look better than just using filler. Using our own method for filling larger gaps of approx 4mm and above, we fill the gaps with wood slivers. Hello Scott, I wonder if you have a recommendation for a wood filler that could fill gaps in a pre-finished wood floor. Plain and simple caulk is for joints….between 2 pieces of wood where they meet.filling gaps in wood

Whenever possible, fill wide gaps and cracks with slivers of the same kind of wood used in your project, as shown in photo. But don’t wait until the end of the job either because the filler that sticks in the wood grain around the void you’ve filled needs to be completely removed or it will look like a liitle halo around each filled spot, once the finish is applied. When you’re building a project out of a knotty or rustic wood like alder, pine, mesquite or hickory, you can give thoseĀ boards a fantastic boost in stability and appearance by filling the cracks with wood filler, glue mixed with sawdust or epoxy.

The door came off the track, fell and broke a large chunk of wood on the bottom of the door. With repairs to site finished flooring that has already been finished use wood putty in the same way you would for filling gaps in prefinished wood floors. I am about to paint an exterior of a very large house with lots of rough sawn wood trim, 50 gallons of paint worth.

My deck railing has become the site of hungery wood bees drilling holes and wood chips indicate wood peckers are enlarging the holes. Unfortunately, you don’t know what the final color of the wood will be where the crack is until you wet out the fiberglass. Great Stuff sticks tenaciously to everything and is very difficult to remove, so if you sprayed it on the trim around the window, you would have a major cleanup project in September or October.

Filling or sealing gaps in floorboards is a very popular topic on Diydoctor and although there are several ways to do this it must always be remembered that, unless you are painting the floor, or are staining it with some very dark stain, the filling method you use will always show up. If there is any damaged wood (rotting etc) in the areas that need to be filled it needs to be removed completely or no filler will hold. Don’t use wood glue and dust to make filler – it always dries more yellow that you think – unsightly! I have used wood filler, but the little demons are back and making holes in my wood filler.

Timing wise I couldn’t get the sawdust from the same wood because I only had the sander for a day. Which ever method you use, the filling is always done before the sanding as the sanding smoothes and flattens the whole surface ready for the varnish. You need to apply wood adhesive on both sides of a sliver and then hammer it in the gap, making sure it sits in firmly. It took the builder eleven years of professional boat building to achieve the perfect hull, but he did it. If you have ever seen a Wood Song canoe (see ) you will see what I mean.
