Polycryl is a concentrate that you dilute with water and soak or brush on your wood. It fortifies and strengthens the wood fibers. It can be used on just the soft areas (brushed on) or the entire piece of wood can be submerged (soaked) in the Polycryl solution. It will dry clear and not yellow your wood.

Density: African blackwood is very hard and heavy. The Average reported specific gravity is 1.08 (ovendry weight/green volume), equal to an air-dried weight of 91 pcf.

Wood products On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4500 lbf (compared with Olneya at 3260 lbf, African blackwood at 2940 lbf, hickory at 1820 lbf, red oak at 1290 lbf, yellow pine at 690 lbf, and Balsa at 100 lbf).

Buckling strength of wooden column depends on slenderness ratio and modulus of elasticity. Is is possible to increase compressive strength of wood? Impregnation of wood by suitable resin or chemical may be an option. Lateral pre-stressing may increase compressive strength.

A chemical bath and a hot-press can transform wood into a material that is stronger than steel, researchers report. First, they boiled different wood types, including oak, in a solution of sodium hydroxide and sodium sulfite for seven hours.

A bed frame or shelving unit made from compressed wood may be slightly bulky to move, but it won’t be as heavy as the same piece made from solid, natural wood. Of course, the lightness of the wood product is a decent indicator of its durability, so keep that in mind when choosing compressed wood for a project.

Apply a coat of clear acrylic sealant to all edges of the boards. Add a layer to any area that might be exposed to moisture. Do this by shaking up the can of sealant, opening the lid with a screwdriver and painting the product onto the wood using a paintbrush.

Use an inexpensive white or gray primer as the first coat. Pressed wood is porous and absorbs paint quickly. You will have to apply more than one coat of primer to seal the wood, because the first coat will be absorbed by the wood. Ensure you have a solid color after applying the primer.

Apply a layer of clear acrylic sealant on all the edges of the particle board pieces. You should also apply a layer to any areas that may be exposed to moisture. To do this, you need to shake the clear acrylic sealant can, open the lid, and then paint the sealant onto the particle board using a paintbrush.

Medium density fiberboard (MDF) is made of very fine wood fibers that are glued and compressed under great pressure . Particleboard is a combination of wood chips, shavings, fibers, and adhesives. MDF is not as hard as plywood and can be damaged easily when roughly handled. Low Strength.
