![]() ![]() These gaps reduce adhesion between materials, leading to weak points where water seepage can occur, leading to bubbling or wet spots on walls. If corners, joints and other areas are inadequately sealed or packed with joint compound, then this can leave gaps for moisture to penetrate behind the wall/substrate, causing damage to both it as well as any paper-based material such as drywall mesh tape. Inadequate Sealing or Packing of Joins, Corners, and Other Areas It may also have poor light diffusion properties resulting in shadows on the wall surface, which can further exacerbate any irregularities and cause issues with adhesion when applying drywall paper tape. The sticky consistency of low-quality joint compounds makes them hard to apply evenly and increases the chances of air pockets forming between them and the wall substrate. Poor quality joint compound can also be responsible for drywall tape rippling. ![]() This is because the paper tape and joint compound form an uneven bond that does not provide adequate coverage and support for the drywall tape itself. When too little joint compound is used, it creates air pockets beneath the tape, which leads to an uneven surface, causing ripples to appear.Īlso, if the joint compound is not sanded properly or applied in too large of quantities at once, these problems can also cause ripples on the drywall tape’s surface. When joint compound is not applied properly, it can result in a ripple effect on the drywall surface. Relevant Article To Read: Does plywood work for stacked stones? Improperly Applied Joint Compound What began with a relatively simple task can end up wreaking havoc on surfaces if not done correctly. Over time as the compounds dry out, these weaknesses become exposed. Later downlines, such as temperature variations, could lead to some bubbling or wrinkles along seams when exposed again through further drying out within an environment over time.Īside from that, poor sanding techniques can lead to missed contact points, causing fractures and, ultimately, buckling in the surface of seams. If proper adhesion is not achieved when applying pressure between layers during installation, this weakens their bond and reduces their ability to resist outward forces. Improper installation methods are another common contributing factor toward visible rippling in drywall tapes after installation. This can also lead to visible rippling along seams where tapes have been installed. High humidity levels can cause moisture build-up within walls, leading to weakened adhesion between layers of joint compound and wallpaper, resulting in bubbling or wrinkles.Ĭonversely, extremely low moisture levels within an area can increase tension between different layers leading them to pull away from each other, causing shrinkage gaps. Temperature and humidity variations within a space are another common cause for drywall tape ripples after installation. Possibly a Good Match: How Much Paint Does A Paint Sprayer Use?

Improper cleaning of the surface before taping can reduce adhesion and make it more likely for rippling or bubbling of the drywall tape over time.Īlso, uneven surfaces, such as areas with high ridges and low depressions, can create tension between the drywall paper and the wall surface, causing it to buckle and wrinkle over time. ![]() When a wall surface has not been adequately prepared before taping or mudding, this can also lead to a noticeable ripple effect in the drywall tape. ![]()
