When applying paint to fresh plaster, it is generally recommended to use at least two mist coats. A mist coat is a thinned-down emulsion (usually water-based paint mixed with water at a ratio of about 80% paint to 20% water). Applying mist coats is crucial because fresh plaster is highly absorbent, and without a properly diluted initial layer, the subsequent paint layers may not adhere well or could peel off. The first mist coat penetrates the plaster, sealing it and creating a better surface for the following layers of paint. After the first mist coat has dried completely, inspect the surface. Sometimes, if the plaster is especially porous or if the base layer absorbed unevenly, a second mist coat may be necessary to ensure an even and stable substrate for the topcoats. Allow sufficient drying time between coats as per the paint manufacturer's instructions, typically 24 hours. Remember, the key to a successful paint job on fresh plaster is the preparation stage, and the application of mist coats is an integral part of that process.
Resin rings are generally considered safe for wear. The primary material, epoxy resin, becomes inert and non-reactive once properly cured. However, during the curing process, the chemicals can emit fumes which are hazardous to inhale and can irritate the skin. It's crucial for the artisans crafting these rings to follow safe handling procedures, including wearing gloves and working in well-ventilated areas. For wearers, allergic reactions are rare but possible, particularly for those with sensitivities to components in the resin or added embellishments. High-quality resin rings, properly cured, offer minimal risk and are durable, water-resistant, and non-toxic. Before purchasing, it is advised to check with the maker about their production processes and materials to ensure that the ring is safe for personal use. As with any jewelry piece, wearing resin rings continuously over time, especially in harsh conditions or exposing them to chemicals, could potentially lead to wear and tear, releasing small amounts of substances. For utmost safety, periodic breaks from wearing any resin jewelry can minimize any potential risk.
