			<content:encoded><![CDATA[<p style="text-align: center;"><strong>Factors Affecting 100% Acrylic or Latex Paint Touch-Ups </strong></p>
<p>How many times has it happened having the same can of paint used a few years before, touching up same color, it does not match? Here, we will discuss the reasons that contribute to these instances, helping elevating the uncomfortable situation.</p>
<p><strong>A. How Paint Appearance Can Differ </strong></p>
<ol>
<li>Color: The hue of the subsequently applied paint could be lighter or darker, if not adequately re-mixed on original painting, or newer one. Both times, latex paint needs to be mixed thoroughly for at least 5 minutes.</li>
<li>Sheen: Sheen or Gloss can be different from areas surrounding newer touched up areas from just being fresh-newer to older and duller painted areas. What&#8217;s found to help is wetting the painting area first, lightly going over with paint.</li>
<li>Mill Thickness: Touch-up can be noticeably different, depending on how much build up of paint is laying on top of older. Good way to elevate this, is to &#8220;Feather&#8221; out the area, brushing to a dry layer on all edges.</li>
</ol>
<p><strong>B. Variables that can Contribute to Touch-up Problems:</strong></p>
<ol>
<li>Applying paint at <a href="http://paintingdenver.net/blog/2009/10/exterior-house-painting-drying-rates/" target="_self">different temperatures</a>: Touching up at an extreme different temperature hotter or colder can see a difference once the paint has dried. Try painting during same temperatures, or close to the same.</li>
<li>Using different methods of application: Several methods of original application can be used to get satisfactory results, however depending on the substrate and texture, a brush can look somewhat different than a previously sprayed application. This happens generally on smooth surfaces such as exterior doors, and schedule 5 drywall surfaces which are slick smooth walls. Way to help, is spray back into container the extra paint, sealing up, to use at a later time. A previously sprayed paint will look closer to the same as before, even brushed if sprayed and saved into container to re-use.</li>
</ol>
<p><strong>C. Tips for Avoiding Touch-up Problems:</strong></p>
<ol>
<li>Apply PVA primer before drywall texture, allowing texture to go on uniform-ally and consistent in nature.</li>
<li>Apply PVA primer after texture, sealing the porosity of drywall, allowing paint coating to lay evenly.</li>
<li>Back-rolling is helpful after spraying, actually dunking roller into paint, and not dry rolling. This lays more paint on surface, giving a very small textured look called stipple. This allows touch-ups to be done much easier, down the road. On flat and smooth drywall, a 1/2&#8243; roller skin should be used acquiring that stipple look.</li>
</ol>
<p style="text-align: center;"><strong>Keeping the Sheen Constant Painting New Drywall</strong></p>
<p style="text-align: left;"><strong>A. Check drywall joints:</strong></p>
<ol>
<li>To be floated or smoothed, and edges sanded, not having dimples, cracks, or ridges.</li>
<li>Check area at low lighting and also at high at all different angles</li>
<li>Last sanding should be wet sanded, giving the most smoothest finish</li>
</ol>
<p><strong>B. Use Appropriate Primer:</strong></p>
<ol>
<li>Interior drywall should have a PVA flat primer.</li>
<li>PVA spread rate is much different than finish coat, in that PVA&#8217;s cover normally twice as far, around 425 sq. ft. of surface per gallon. Apply just enough to seal new drywall from finish paints coat absorption.</li>
</ol>
<p><strong>C. Back-Rolling:</strong></p>
<ol>
<li>A higher quality Lambs Wool Skin Cover will apply paint more evenly and heavier than an economically priced one will do.</li>
<li>Keep roller strokes the same direction, as vertical as possible, keeping same pressure on roller when either rolling out or back rolling.</li>
<li>Keep roller loaded with paint, not allowing to dry-roll out edges, unless your spot painting for touch-ups.</li>
<li>Keep roller frame the same across the entire wall, never &#8220;Flipping&#8221; frame back and forth down the same wall when back rolling.</li>
<li>Rolling out final coat or back rolling will provide surface uniformity, especially on a flat smooth Schedule 5 drywall finish, leaving a paint stipple.</li>
<li>Dry time is important painting multiple coats, when a deep tint base paint is being used. Generally this time is about 2 hours at 70 degrees, so paint does not blister with added coat.</li>
