Make any necessary repairs to stop the moisture, then dry out the ceiling with fans. Take up peeling flooring to allow the surface of the subfloor to dry out.
If the vinyl is glued, you have two options. Although scraping is difficult, you should do it if the subfloor is spongy. You'll probably be able to pull the vinyl off of the wettest areas without scraping. Allow the Softener to remain on the surface for at least minutes longer is better! Do not allow the material to dry. Wipe away excess material using a dry, soft cloth.
In extreme situations, additional applications may be necessary. Rinse the area with clean water and allow to dry. Wipe the soapy film off using a separate cloth. Apply the vinyl conditioner to a clean cloth and rub it over the vinyl.
Wait for the conditioner to absorb and wipe the vinyl dry. Repeat until the vinyl has softened. This article was written by the It Still Works team, copy edited and fact checked through a multi-point auditing system, in efforts to ensure our readers only receive the best information.
A mixed solvent of methanol and water enables the fabrication of this blend monolith, whereas the PVA monolith is formed in an aqueous acetone. To our best knowledge, SA is incorporated in polymer monoliths by selection of appropriate phase separation conditions for the first time.
All other reagents and solvents were used as received. The monolith is then immersed into the calcium chloride solution for ionical cross-linking of SA. The samples are cut with a scalpel and coated with a thin layer of gold using an ion sputter apparatus E Ion Sputter, Hitachi Ltd, Tokyo, Japan. Porosity of the monolith samples is measured using a gravimetric method according to the following equation:.
For the fabrication process, selection of non-solvent and the ratio of solvent and non-solvent are crucial factors for the formation of the blend monolith. The detailed screening of the phase separation solvent shows that a mixture of water and methanol with a ratio of is the most suitable.
Intriguingly, the PVA monolith with good mechanical strength is not formed in this solvent. These behaviors can be rationalized as follows. After adding methanol into the polymer solution, the mixed solvent system transforms into polymer-rich phase and polymer-lean phase. As the amount of non-solvent methanol increases, the polymer segments in the polymer-rich phase become folded and aggregated, leading to the increase of the concentration in the polymer-rich phase.
When the increasing concentration reaches to a certain degree, the phase separation takes place. In the case of a smaller amount of non-solvent, the concentration of polymer-rich phase is not high enough to induce the phase separation; while for a much larger amount of non-solvent, a mass of polymer segments aggregate rapidly, resulting in precipitation of the polymer in the phase separation system.
Without this step, the blend monolith turns out to be drastically shrunk in the drying process and the pore structure is not maintained any more. The mixed ratio strongly affects the formation of the blend monolith. Similar pore structures are observed in all the blend monoliths. With increasing the content of SA, the skeleton size increases and the pore size decreases, which affect the interconnectivity of the pore structure. This behavior is explained as follows [ 16 ].
The viscosity of the solution increases with increasing the content of SA, which leads to the higher degree of entanglement and the slower dynamics of phase separation. Furthermore, the formation of the soluble complex between PVA and SA may also delay the phase separation process.
It belongs to a type II isotherm which is formed by a macroporous absorbent. This hysteresis loop is caused by capillary condensation, suggesting the existence of more or less slit-like nanoscale porous structures in the present blend monolith [ 17 ].Oct 13, · Re: Looking for a product to help soften marine vinyl Another thing you might try id D&L hand cleaner availiable at most automotive stores, it has lanolin in it which make the vinyl very soft and supple and is a great cleaner.
